| Video Discription | Echinodermata is a phylum of invertebrate animals that includes 5-sided or radially sysmetrical animals such as starfish, sea cucumbers, sea urchins, heart urchins, sand dollars, and crinoids. This video on echinoderm paleontology covers echinoderm diversity, ecology, anatomy, morphology, evolution, and similarities to humans, as well as echinoderm classification, including classes of starfish / sea stars, brittle stars, sea cucumbers, with a focus on blastoids, crinoids (feather stars), and echinoids (sea urchins, heart urchins, and sand dollars). Echinoderms can either live attached to the seafloor as benthic animals or move or swim freely even as predators, such as starfish. Crinoids are not very common on modern Earth, but dominated benthic ecosystems at certain times in Earth's history. Crinoids take many forms and in the video I break down the major types of crinoids (monocyclic vs dicyclic crinoids and inadunate vs flexible vs camerate vs articulate crinoids). Echinoids have not exhibited as much diversity as crinoids throughout Earth's history, but they do have many body parts, which I label and discuss in this video. Crinoids and echinoids are related but live in very different environments. Crinoids live in a wide ranges of depths, but echinoids, prefer shallow water and even beach environments. Some echinoids can even burrow to live or eat in the sediment. As is the case for most invertebrate animals, echinoids underwent major evolutionary advances in the Paleozoic and Mesozoic Eras, which I discuss at the end of the video. Echinoderms are surprisingly the most closely related to vertebrate animals of all the invertebrates. Hope you enjoyed! ;D Reference: Prothero, D.R. (2013).
