The class Ophiuroidea consists of over 2,000 species collectively known as Ophiuroids. With so many species, the class Ophiuroidea is one of the most diverse groups of marine organisms. In the oceans and sea, they are commonly found living in the rock and coral crevices or clinging to ...
Deuterostomia is a major subgroup of animals. It is comprised of two lineages, theChordataandAmbulacraria(Edgecombe et al. 2011, Swalla & Smith 2008). Chordata consists of two exclusively marine groups, the fish-like lancelets (Cephalocordata) and the sea squirts, salps and relatives (Tunic...
A phyla of animals that has evolved specifically to feed on organisms on or near the floor of a water-body, echinoderms come in many shapes and sizes. While most people are likely familiar with star fish (sea stars), other examples include sea cucumbers, brittle stars, and sea urchins....
Class Crinoidea is found in the subphylum Pelmatozoa. Crinoidea refers to a class of marine animals known as crinoids or sea lilies, which are characterized by their flower-like appearance and long, feathery arms. Pelmatozoa is a subphylum of echinoderms, which includes organisms such as sea...

In summary, as indicated by recent studies of molecular phylogeny and comparative genomics, vertebrates are unique among bilaterians and distinct from invertebrates. Taking these findings into consideration, it is evident that the prospective phylum Vertebrata is the first clearly classifiable animal ...
