[@Cranialdrilling]

Wow, that's really interesting. Reminds me of that 2008 horror movie "Teeth". For those unfamiliar, it's a story about a high-school girl named Dawn with Vagina Dentata. If you don't know what that is (the name's a big clue😂), it's an ancient myth that has existed in a varying degree across many cultures worldwide. It translates to "toothed vagina". Pretty crazy overall and the variation between cultures is quite interesting. Some believe that the legend played a role in the adoption of female genital mutilation in some African cultures (so effed up) as well as the higher prevalence of rape in some cultures. Also, the Rape-X anti-rape device was produced with this "toothed vagina" idea in mind. As far as any truth to the legend, some believe the idea may have evolved from the discovery of Dermoid Cysts (Cystic Teratomas) in the ovaries, uterus (and much more rarely the vagina itself) although they can occur in other locations throughout the body. Dermoid Teratomas are highly irregular tumors (usually benign) that can contain a diversity of mature tissues including ectodermal (skin, brain), mesodermal (muscle, fat), endodermal (mucosal tissue, ciliated epithelium), thyroid, hair, and of course TEETH!! Pretty friggin crazy 😬😬 There was also a case of a woman from the UK who had a bladder mesh surgery in which improper placement resulted in the mesh migrating and eroding through the vaginal wall (OUCH). Two years post op while becoming intimate, the jagged-edged mesh badly injured her partner's genitals by cutting as teeth would. Eventually it ended up being removed, after causing and then resulting in further complications. Medicine/science=🤯

[@lindawithsharks]

As someone who works with sharks and rays every day I can tell you: yes the cannibalism is specifically in Sandtiger sharks. And actually you were correct, the stingray is a type of eagle ray called myliobatis. All eagle rays are stingrays though. So both eagle ray and stingray are correct 😁 and on another note: both rays and sharks have species that give birth to live young and species that lay eggs called mermaid pouches.

[@Cailloumax]

So not all ovoviviparous shark have intra utero cannibalism ? I thought so

[@CodaBlair]

There's actually a really cool moment in an epsiode of the show River Monsters, where while working together with scientists while trying to investigate whether giant freshwater stingrays could be a cause of certain incidents, one of them he catches ended up being a pregnant female about to give birth. So what they do is drag her to land and make it so they could not onky help her, but also be able to tag her along with her newborn babies (since they are, or at least were, an endangered species). Once they ensures all of them were okay, they were all released together.

[@Rae_24_]

I actually read yesterday that scientists suspect that the Megalodon also was like this, where the unborn but very much alive babies would eat other embryos in the womb. The article said something along the lines of "there may not have been a lot of babies in each litter, but they sure had the nutrients they needed to become super sharks" and that stuck with me. They've also reported that they have found small, juvenile and baby sized teeth that they suspect to be young Megalodons in some shallower waters, suggesting that the mothers gave birth close to shores where the young could spend their adolescence. In the article, they called these "nurseries"

I'm not a vet, much less an exotic vet that works with marine life. But I've seen a number of dolphin births, and each one I've seen comes out tail first. I looked it up and according to what I read on line (whether it's accurate or not, I don't know, but it makes sure), the reason they come out tail first is to minimize the risk of the baby drowning, as the birth can take several hours. Really cool video (said as an animal lover).

[@zlcoad1]

I have seen a dolphin be born head first, although I think this is their version of breech

[@VeraBean]

Okay I need to ask, how have you seen a number of dolphin births? Just videos or irl?

[@Whateverhasbeenmynameforyears]

Yup any mammal who gives birth in the water goes but so they have longer to give birth before the baby needs to breath. Notice the hippo did too?

[@ajplays7241]

Go to any aquarium and u prob can see specially a couple years ago when they got in trouble that starts w S and ends w D

[@princessofwhales4160]

Marine biologist here! Dolphins typically give birth tail-first because it gives the tail flukes time to become rigid outside the body which helps baby swim better! In utero, the flukes (and dorsal fin) are very soft and pliable so birth is easier for mom. Observations on wild killer whales, who are large dolphins, showed that the dorsal becomes rigid within the first day or two after birth

[@heleninglis9961]

With the hammerhead, it could have been deceased. Ive seen videos before where the mother had passed away & washed up to shore, then when people discover the body, they see the babies moving about inside, through the body, so to give the babies a chance they pull them out & release them. Sharks are basically on their own from the moment they're born.

[@AcerJones21]

This was my thought as well. I think I vaguely recall seeing a video like this too, if not this one. I don't think many people would mess with a shark and its privates if it wasn't dead already.

[@diabeticsrule1763]

Also, they do occasionally get beached (sharks some much closer to shore than most people realize), so it is very well possible that those people were trying to get it back into the water and then it started giving birth, so they focused on getting the babies into the water

[@Dekubud]

I was thinking it's probably the case as well since sharks needs to swim to keep breathing and the mother shark didn't seem to be moving at all on her own. I'm glad the guys decided to rescue the baby sharks however!

[@gnarthdarkanen7464]

Yeah, while sharks DO often get a LOT closer to shore than people expect or realize, it's pretty rare for even a brooding mother to let herself get THAT close... Something was "wrong" from the start, because she wasn't even trying to get away... I couldn't say for sure that she was dead, because it might only be the water pushing her body around... but there WAS some movement.. ...AND it's entirely possible that "in the throws of birthing" she was just washed perilously close to sand and got beached... I'd rate it "disturbing", because there was definite danger to everyone involved, all things considered... BUT I wouldn't get angry about it. Once a shark that size is in (what we consider) knee-deep water, it's really tough for them to get back out to swimming again... AND humans don't do so well trying to help in deep, foamy, swirling water all thrashing around in the dark after a pregnant mother and babies coming out... SO... sometimes you just gotta do what you gotta do. ;o)

[@Miipmiip]

Hammersharks are really interesting, they can even fertilise themselves if they have to

[@idaamundsen9556]

Vet here, you're not technically wrong in believing the rays hatch from eggs. They do, only the hatching happens inside mom (I think the sand sharks are the same), its something called being ovoviviparous and several species of sharks, rays, snakes and fish reproduce like that :)

[@beyedoc]

[@NIkki-ox1ej]

[@thesadtoast]

Dolpins always come out tail first, this way if the birth is long or stressful, they don't drown. Most sharks normally abandon their newborns after birth, except some rays who protect their offspring. Some sharks leave their eggs after laying them, some give live birth, some do like the tigershark, letting the babies eat each other. Nature is just weird

[@venlakirahvi]

EDIT. I had misunderstood the matter, look for a correct and much more informed comment in the replies! My original comment: Vet student here. My favorite fact about animal repro I've learned so far is probably the way chicken can store sperm cells from several males within their repro system (for a few weeks) and pick and choose which ones to actually use for insemination. This both maximizes the rate of reproduction AND allows the chicken to eject the sperm from less desirable roosters.

[@highwaysstar]

Any idea how they choose the sperm cells they want? Would that we could expel undesirable sperm as well.

[@CatVetNele]

Oh wauw, You're learning about those things? So cool! We never had much education on poultry, unless that's what you choose for your last speciality year. Where are you from!

[@venlakirahvi]

@@CatVetNele I'm studying in Sweden. When it comes to the Vet programme, we have a policy called "Day 1 Competence". It means that we all should manage all different kinds of jobs that veterinarians can be employed in, on the first day after we graduate. That's why everyone has the same courses and gets a well rounded education - including poultry, for example. There are only a couple of weeks during the whole programme where we can choose what to study.

[@venlakirahvi]

@@highwaysstar Unfortunately no, I agree it would be cool to know how they manage this. Also I see now I was a little unclear, my understanding is that they only can pick and choose between sperm cells that come from different males - not between each individual sperm cell. Maybe they store the sperm in different places, or mark it somehow?

[@laurenwallace8204]

One of the things that makes sharks so interesting is the variety in how they reproduce! Some species do lay eggs while others give live birth. While the sand tiger shark feeds its embryo with other embryos/eggs, other species such as the hammerhead seen in the other clip have “pseudoplacentas” which are formed from the yolk sac and analogous to those in mammals. The bonnet head shark has also been observed to use asexual reproduction through the fertilization of an egg by a polar body when a mate cannot be found.

And another comment: animal repro is so interesting, especially when you get into the anatomy and physiology. it varies so much between species. Like horses have a diffuse placenta, cows have a cotyledonary placenta. Camelids like llamas and alpacas usually give birth during the day (morning time) and horses usually give birth at night. Or how a cow with a retained placenta will usually be fine with abx and (possibly) a uterine flush, but in horses it's a medical emergency.

I think Lemon Sharks have embryonic cannibalism as well. They do have nurseries that are located amongst tree root (mangroves maybe) because the adult Lemons will actively hunt infant and adolescent Lemons. Dolphins are usually born tail first. Since their tails are curled and soft for the birthing process, the birth stalls for a bit after the tail is pushed out, allowing the newborn’s tail to stiffen while the mother is swimming. It helps the infant swim better as soon as it’s born. For another interesting water birth, look up sea horses giving birth. It’s pretty cool to watch. Love your videos!

As far as I know dolphin babies do usually come out tail first. Other commenters have talked about it reducing the risk of the baby drowning. It also means that when the baby finishes coming out and starts swimming, it will be swimming in the same direction as the mother, so it's easier for them to find each other and stay together.

[@ShadowLightMewEndlessOceanMew]

The calf doesn't really swim exactly, they are carried by their mother's slipstream. Of course right after birth they have to immediately start swimming and get that first breath. Their tail fluke hardens over time so they depend on their mother's slipstream until it has hardened and they can start putting in their own effort

[@SomeoneBeginingWithI]

@@ShadowLightMewEndlessOceanMew That makes sense.

About the mouth-brooding fish: this is worth doing for the parents because fish eggs and newly hatched baby fish have a very high chance of being eaten if they're out on their own in the ocean. Depending on the species, maybe less than 1% will make it to adulthood. I'm not familiar with these mouth-brooding fish, but I would guess that they probably don't eat while the babies are in their mouth. I know that mouth-brooding toads don't eat when they have a mouthfull of tadpoles. They probably make sure they eat enough before the mouthbrooding starts that they have enough stored energy to make it through the mouthbrooding period without eating

@@katie85705 HIPAA doesn't even apply in NZ and I don't know the equivalent, but my concern is that because it's the doctor's channel/video that the info was disclosed on, even if it's someone else doing the disclosure who isn't subject to whatever NZ's version of HIPAA, just having the disclosure posted on her content could open her to being held legally liable, in the same way that a provider responding to a negative review of them on a website is a HIPAA violation because it confirms that the complainant is a patient publicly. I think you both are probably right, and it is highly unlikely to be pursued in either case, but with medicolegal issues it's best to err to over-cautious than under in general.

Another form of extreme animal reproduction I'd love to see you tackle: obligate brood parasites. These are birds who don't have the ability to build nests, so they lay their eggs in other species' nests and trick the owners into raising the chick as if it were their own. I've always considered that to be a dirty move, but nature plays for keeps.

[@KaliqueClawthorne]

Damn - And the english name is just that? In _German it is their sound :D The name of the bird in German is literally : Kuckuk Also as I know the nestling than kicks out his nest-siblings because it becomes often way bigger then the other babies so it needs place.

Sharks and relatives have the weirdest gestational adaptations. It varies a lot, from a simple egg laid without guarding to full placenta analogies and intrauterine milk, full spectrum. In bony fishes, there is plenty of weirdness too, from seahorses where the male is pregnant to guppies who don't have a uterus so they carry their eggs full term to hatching inside their ovaries

[@ahmedm6228]

Just a quick suggestion to the editor: When editing these reaction videos, please make sure that the sound volume of the videos being reacted to matches the reaction video. Sometimes I watch videos at night and I have to lower the volume. When I do so, I can hardly hear the sound of the video being reacted to. And if I increase the volume, the reaction becomes too loud. So, I find myself having to increase/decrease the sound volume repeatedly.

The dolphin birth was amazing. Momma got you boo. She stays right under baby so it goes up for a breath n just omgosh the cuteness

[@jheeshin621]

13:31 Actually yes, labor can last for many hours (according to 1 article, the average for Common Bottlenose Dolphins is about 8 hours), so calves are typically born tailfirst to mitigate the need for the calf to hold his/her breath for those several hours. Headfirst births also occur but they are rarer. The dorsal fin and tail fins are, indeed, very floppy at first to make the birth easier for both mother and calf, but they stiffen with time. Whales and dolphins are precocial mammals (they are born with the ability to move on their own, as opposed to altricial mammals like humans which are the opposite), so although calves may be somewhat clumsy and uncoordinated, they can still swim relatively well right after delivery. Once the calf is born, he/she must get to the surface to breathe within a minute to avoid suffocating; the mother remains nearby to assist if needed. Calves must also adjust to feel comfortable with the position of their blowhole, so during their first days of life they chin-slap (lift their entire head out of the water, as opposed to just exposing the blowhole like older calves, juveniles and adults do), and they must learn how to hold their breath, which is important especially when it comes to nursing. (I've split up the comment so that it wouldn't be too long; you can find the second section...somewhere)

[@cynhanrahan4012]

Dorsal fins in marine mammals are controlled by a muscular structure. So babies are a bit floppy. Also captive marine mammals don't get enough exercise to maintain a straight up dorsal, which is why "marine parks" marine mammals dorsals often flop over.

[@ShadowLightMewEndlessOceanMew]

This is not correct, dorsal fins are pure skin and meat. They flop over due to gravity pulling and swim pressures. It actually happens in the wild too since some Dolphin and even Orca populations expose their dorsal fins to situations they just aren't equipped for. Some swim circles around prey a lot as a hunting technique which affects the dorsal, making it bend into a direction. Orcas that beach themselves to grab prey expose their heavy dorsal fins to gravity and eventually the dorsal fin does lose that battle. Also they are in human care and many Dolphin generations have been born and raised successfully in human care

[@justabookworm1382]

I just looked it up, and the dorsal fin is not a muscle, like Shadow said it isn't. The baby's fin usually stiffen up after a few hours, too.

[@kassy9049]

ShadowLightMew is close though. They're made up of connective tissue, no bone muscle or cartilage in there to keep them upright. For the babies, they will stiffen up after a bit, but it is plenty common for them to flop over as they age both in zoological facilities and in the wild. Scientists don't actually know for sure what makes them flop over, but the leading theory last I checked was sun warming the fin, most of the dolphins who have curved fins in the ocean (including orcas) are not in far migrating pods or, like shadow mentioned, circle prey often (sometimes bringing them to the surface, though I'm sure water pressure wouldn't help if they were already flopping over). So in the ocean if they don't migrate far they can hang out at the surface more often. Similarly, in zoos their food comes to them so they can relax much more often and sunbathe, which could be why it's so much more common in zoos than in the ocean. It's nothing to do with exercise though, they don't have any muscles there, they can't "work out" their dorsal fins. They can't control it either, once it flops over it stays flopped. It's like dog ears, they all started perked up, but as they were domesticated they flopped over in some species because they didn't need them. Different original cause, but in both cases the change is permanent, not controlled by the animal, and doesn't say anything about their health, it's purely cosmetic.

[@ShadowLightMewEndlessOceanMew]

@@kassy9049 Concentrated sunlight can indeed affect things too and make them go soft and more kneadable. Didn't hear of it being related to dorsal fins before though, is an interesting thought. The most i have seen is rescued sunburned Dolphins that were heavily sun exposed due to stranding or having been stuck. Next time such a case happens, i will see if the photos show an affected dorsal fin as well. And yeah normally dorsal fins are held up and supported by underwater pressure but not all pods and ecotypes stayed bound to the depths. Some started and continue to be shallow water hunters or choose prey that are on land like Sea Lions and Penguins. Not all wild pods can be watched 24/7 but dorsal collpase is known in Transients and maybe someday others will be documented with them as well. It is indeed more common in human care since all the activities and wanted stimulants are above the water. They do try and have toys and other enrichment underwater but whenever a trainer shows up, they will surface and even slide out to try get attention. Some still haven't gotten their dorsal fin collapsed but as they grow taller and heavier, gravity is waiting around the corner

They also said she died in the most blase way possible and we never see the family's reaction.
