Animals: Tour of 9 Phyla

[@AmoebaSisters]

A correction we fixed (thank you so much for the comment!) at 10:42 - we needed to place our *lancelet* and *NOT the lamprey* . While the vertebrate in the lamprey are reduced or absent (cartilaginous) - it's still classified as a primitive vertebrate animal so it's not an example of an invertebrate animal in Chordata. Lancelet would be an invertebrate example in Chordata. We also have a clarification at 2:41: we don't mean to imply that the directional word anterior is defined as animal's head. Tissue is focused in the anterior part of animal, forming a head area. *Expand comment for table of contents* This video introduces some pretty advanced vocab including cephalization, coelom, protostome, deuterostome, & more! If you want to skip ahead to the animal phyla, you'll find the vid has chapters or view timestamps below! :) 00:00 Intro 1:11 What Is An Animal? 1:57 Symmetry 2:33 Cephalization 2:57 Protostomes vs Deuterostomes 3:52 Triploblastic Animals 4:20 Coelom 4:50 Start of Phylum Tour 4:55 Porifera 5:28 Cnidaria 6:03 Platyhelminthes 6:34 Nematoda 7:32 Mollusca 8:04 Annelida 8:32 Arthropoda 9:09 Echinodermata 10:30 Chordata 11:45 More to Explore

You could have used sea squirts as an example of an invertebrate chordate. Simply because they are weird.

The Amoeba Sisters are one of the only teachers that have made me laugh during a lesson. Pinky, your narration is so simple and enthusiastic, you perfectly simplify the topic while keeping me engaged and your occasional jokes make me chuckle. Petunia, your drawings are so adorably and iconically cartoony. They're pleasing to look at and do a great job of representing what is being told. Your visual gags also bring a smile to my face and a laugh out of my mouth. You two work so well together to make science fun, engaging, and helpful. Please never stop making videos, you've been a huge lifesaver to so many of us! Keep up the great work!

I thought you were gona stop at the high school level of biology. Apparently you are going to cover ALL OF THE BIOLOGY at some point and I am really glad for that. I am a pharmacy student in Greece and this was the 1st video that I had 0 clues going in, I learnt a lot. Thank you! Also great Video, really liked it.

I am a university student and I find this very helpful especially the alphabetical mnemonics for the protostome, thank you!

[@dweebteambuilderjones7627]

10:46 Lampreys are vertebrates as they are classified as agnathans, which are vertebrates. A better example of a non-vertebrate chordate would've been a tunicate.

[@AmoebaSisters]

You are absolutely right, we should have put our Lancelet there! We will make a correction, thanks so much.

[@Foxtrot12345]

I love that Petunia's favorite animal is the Maned Wolf. Not quite a canine and not quite a wolf; it always fascinates me how animals are labeled and what classification they're given. My second favorite animal is the Spotted Hyena, which also has it's own classification. I'm hoping eventually I get my master's degree in Zoology and focus on specific fields, but for now, this video was a great way of introducing the basic concepts of Zoology.

amazing

[@osliec]

Ahh yes, finally some real biology...! Just kidding, but holding a PhD in Zoology on the subject of evolution in some specific Crustacean groups does tend to make one a bit biased! Just a little curious to hear about your courses in evolution that didn't include zoology? Sounds a bit strange... But I'd advice against going to the path of trying to understand coeloms. It seemed a nice and relatively clear way of dividing animals back in the day, but when examined in detail, it is really complex and also not very clear precisely what is happening. But as always, a great video and GOOOOO WORMS!! ;-)) PS: Crustaceans are the coolest arthropods!

[@muhammadarmaghan9360]

I just love the way you teach. I also have a request can you please make a video on spermatogenesis and oogenesis I really need to get a grip on these topics.

[@TailsOfficial1992]

Nice Video Amoeba Sisters :)

[@sciencenerd7639]

I relate to this so much. I switched my major from biology to biochem. Really regret that I never have had the opportunity to take a bunch of zoology classes. But I guess that's what happens when you like every bit of the natural sciences, there is never enough time for everything.

[@romeoxx9721]

Thank You.

0:30 relatable How much she talks about cells 1:30 me Nitpick: they talk about radial symmetry yet draw the sea star as having two eyes instead of five Boo I hate these animal designs %\ Come on there supposed too be showing us how different every phylum is stop givong them the exact same face smh Things i learned: A chordates anus forms before there mouth Tape worms dont have a anus The rest is pretty basic stuff %\ Getting bored Mentions sea stars can regenerate but not sponges? Why? 11:30 most have bilateral symmetry but theres also tunicates 11:45 OMG THEY MENTIONED THE RARE ONES Pretty good video for starting out anyways

Love your content as always. You mentioned starfish under radial symmetry, but they actually fall under bilateral symmetry by evolution.

[@AmoebaSisters]

Hi there! In this video, we're just focusing on body plan symmetry and echinoderms are especially interesting! We mention the larvae of echinoderms, like sea stars, generally are bilateral (9:19 ) but the adults of most echinoderms have radial symmetry [or more specifically pentaradial]. We're using the definition of radial from our sources in the description, but we also like this one from Berkeley's glossary: evolution.berkeley.edu/glossary/radial-symmetry/ However, it would be really neat to have a video that focuses on the phylogeny and discussed bilateral ancestral echinoderms.
