Description
Got a few more things coming for my 200 animal drawing challenge! 
Fun fact: echinoderms like sea stars, sea urchins, and sea cucumbers are our closest invertebrate relatives! How do we know this? Embryo development! When embryos first start building their digestive tract, most of them start mouth first, anus second. In vertebrates and echinoderms though, it's the opposite... Yes, that's right. We develop butt first lmao.
If anyone else wants to join in the link is below! Bear in mind that the challenge overall is pretty bird/mammal/prehistoric animal heavy (I am biased lol,) but since I'm working in order it'll be a lot of invertebrate uploads to start with.
