I love these critters. One of my favorite beings ever. I've gotten to tag them for a few years. I do classes on them from time to time. They are so critical to our ecosystem on the east coast. Their eggs are a primary food source for many shore birds. Amazing creatures. Please try to love them and never pick them up by their tail. If you must hold them, try to hold them like you'd hold a bowl with both hands. They are docile and they don't have teeth to bite you and the tail does not have a poisoned stinger or barb. The tails are mostly used to right themselves if they end up on their backs. Their numbers are in decline and it takes approximately 12 years for a horseshoe crab to get to maturity. We need to protect them whenever we can.

Wow, I can't believe that I found a new science channel that I had not seen before. And I really could not believe when I saw that you are the writer, narrator, and editor at the same time! I assumed there was a huge team of people behind this. Absolutely incredible work and amazing quality. Keep it up!

[@bazoo513]

I am an avid watcher of well presented science and technology themed content, on YT and elsewhere. As 60-something old physicist by training, IT consultant by occupation and former IAEA expert, it is only occasionally that I stumble upon some nugget of information genuinely new to me. (For actual news I mostly rely on journals.) However, this your video, young lady, opened a whole new area to me. Thank you so much! BTW, your presentation and delivery style evolved so rapidly from that first GMO video that in just few months, if not weeks, it was impossible to tell you were not an experienced, but still enthusiastic, veteran of the field. Your and Brian's sibling channels are pure gold!

[@liriosogno6762]

They also have all their references in the description if you didn't knew! You can read even more about it

As a fellow nerd, are there any channels you would recommend? I find that KZbin is really bad at digging up new stuff for me. My own favorites are: Most of the PBS shows, but especially PBS Space Time. "Sean Carrolls" physics playlist called "The Biggest Ideas in the Universe". "Curious Droid" (general technology information) "Practical Engineering" (mostly infrastructure) "3Blue1Brown" (math) "Applied Science" ("DIY" science, extremely well done, not stuff anyone can do at home) "Tech Ingredients" (DIY technology, like homemade high quality speakers) I also really enjoy "Lex Fridman" (podcast)

[@bazoo513]

@ Pretty much the same. Add "Real Engineering", a kind of this channel's big brother, then "Veritasium", climate and energy focused "Undecided with Matt Ferrell", "Just have a think", "Climate Adam" and "Hot Mess", light pop-sci "Minute Earth" and "Minute Science", more thorough "Kurzgesagt" ("In a nutshell"), a bit iconoclastic physicist Sabine Hossenfelder, then "Mathologer", "Robert Miles" (cryptography), everything by Brady Haran (e.g. "Periodic Videos" and "Objectivity"), "Computerphile", "Up and Atom", "Steve Mould", "exurb1a", "CGP Grey", "Knowing Better". I also follow a number od spaceflight related channels, as well as some on linguistics and generally fun like various by Tom Scott and "Answers with Joe", astronomy ("Cool Worlds" and "DR. Becky") etc.

@@bazoo513 Yeah, I watch a lot of those as well, but they aren't quite at the top. "Steve Mould" was nearly included, but it is a little bit too superficial to make the list for me, despite me watching almost everything he does. "Dr. Becky" I simply forgot. All of the "minute _" are not in-depth enough for me. Periodic videos is more entertainment than information, and as a 3'rd year computer science student the programming channels don't make the cut for me either. Tom Scott and Answers with Joe I also watch, but again that's more entertainment than actual science. All of the spaceflight and CGP Grey are mostly a waste of my time in my opinion. I know the rocket equation, and all the videos are about just that, and minuscule variations of the same things. I would rather watch a video on the actual new materials used in the rockets than how those materials are used in rockets - that's self-explanatory in my opinion. I very nearly included "Isaac Arthur", but that's mostly future stuff and a lot of it won't matter in my lifetime - that's kind of a different topic, but a channel I would recommend to curious people nonetheless.

[@bazoo513]

@ Mostly agree, but I watch mostly for entertainment - not much new info here. That's why I was so pleasantly surprised by this video. I was surprised you don't like CGP Grey (OK, his topics are far broader, like those of "Knowing Better" and "Veritasium", but IMO worth watching.) Computerphile is mostly known stuff for professionals, but there is an occasional gem. Robert Miles (cryptography and AI) is more informative. "Mathologer" is not far from "3brown1blue" - different styles, similar topics. I like to follow spaceflight news - my first stop for that is Scott Manley, with occasionally "Everyday Astronaut" and Fraser Cain Have you tried Curiosity Stream and Nebula streaming service bundle (there authors often plug them) - worth the money (which is barely more than a dollar a month) Enjoy!

Horseshoe crabs: Survived 5 global mass extinctions Humanity: Allow me to introduce myself

[@brianhale3678]

Food vs Evolution. You have the same problems that every organism has whether it's an single cellular organism or a large animal. The darwinists wants you to believe that an organism popped into existence with the ability to find and digest food. But consider the components that have to be in place in your own body in order for that to happen. Eyes to find and identify the food. Nose and taste buds to identify the quality of the food. If you didn't have taste buds you would die from food poisoning. When was the last time you spit something out that tasted rotten. Bones and muscular structure to move yourself towards the food. A month that is designed to intake food and only food and not other matter. A brain to identify the food. The digestive system to transform the food into energy. Which is made up of many complex parts just on its own. An anus to excrete the food waste or you'll explode from food waste buildup. Liver and kidneys. To filter the natural toxic build up inherent to all food. And last but not least, Food itself. Which only comes from the food chain and organisms that would have to already exist. Or you could be born into existence with the ability to manufacture your own food which is called photosynthesis. An extremely complex multi-step process. Which is just as complicated as digestion. And requires the intake of oxygen and water. So it's really just the ability to eat CO2, water, and sunlight. Darwinism wants you to believe that an organism popped into existence with all of these features. Single cellular organisms do not have eyes, mouths, or muscular structure. Actually they do, they just go by different names like... Membrane, Chemical receptor, Mitochondria, Endoplasmic reticulum. Single cellular organisms have all the same basic parts that we do we just call them by different names. And if a single cellular organism existed without every single one of them it would immediately die.

[@eliassis576]

[@brianhale3678]

@@eliassis576 You can play word games. You don't like the word "popped" At the end of the day the first organism needed every single component necessary to collect and process food... or it would have died immediately. No food, no self-replication. No self-replication, no natural selection. No natural selection, no evolution. Therefore all the components necessary to collect and process food must have been in place before Evolution could have happened... Anyone can understand this argument it's not complex. People cling to Evolution because they hate God and His moral authority over us. An empty Universe cannot tell us what to do. An empty universe doesn't care how many sins you commit. God cares a great deal and he will punish every single sin that was not atoned for on the cross of Jesus Christ.

@@eliassis576 I'll leave this here. How do you get to hell? Very simple: claim that you're innocent. How do you get to heaven? Very simple: Admit that you're not Innocent, you're guilty and ask for mercy. How to know if you're guilty or not? Simply: Compare your life to the Ten Commandments God gave you in the Bible. Everyone agrees that if people followed the ten commandments there would be no need for governments or police. Do not lie. Do not steal. Do not commit adultery. Do not insult God by using his name as a cuss word. There are six more but let's just leave it at that. How many lies have you told in your life? Have you ever taken anything that didn't belong to you? Jesus said, if you look at a women lustfully you've already committed adultery in your heart with that woman. How many times a day do you do that? Do you use God's name as a cuss word? Would you do that with your own mother's name? If you answer these questions honestly you know that you're guilty. God can justly punish you and send you to hell. Ask him for mercy. His name is Jesus. It's as simple as this, The Ten Commandments are called the moral law. You and I broke God's laws. Jesus paid the fine. The fine is death. Ezekiel 18:20 - "The soul who sins shall die. That's why Jesus had to die on the cross for our sins. This is why God is able to give us Mercy. Option A. You die for your own sins. Option B. Ask for mercy and accept that Jesus died for you.

I lived on the bay and always loved horseshoe crabs. As a little girl, there were so many horseshoe crabs in mating season that you could dig randomly on the shoreline and find tons of eggs and see adorable baby ones inside. Over the years, the population reduced so dramatically that these days I’d be lucky to spot one or two coming to the shore to mate. I don’t know if that’s due to harvesting, or the polluted waters, but I think it’s the latter, as turtles disappeared as well.

GMO is when human achieve by smartly figure out and manipulate gene than to what the 'nature' takes millenia to achieve. Just like recombinant insulin produce from a GMO rather than haevesting it from animals (igs and cow). Hence, why it is cheaper now and less people die from diabetes (well affordable compared to the US anyway). Anti-GMO is very good at lobbying and advertising to make sure the 'natural' is safer to it a high price tag for it. Scientist do research rigorously especially if it is related to health/drug testing! And this thing is not even injected into or ingested by human. It is just a protein to check if the drug or solution is totally sterile, free from the pyrogen-causing bacteria.

Appreciate the video and the info. Some ways I COULD see them not killing the crabs is reduce the amount of blood taken from each subject.

Heck maybe a recovery facility to ensure they stay healthy until they recover lost blood.
