Currently they have the presence of about 7,000 species , although, throughout the history of the evolution of the Earth's biodiversity, echinoderms had more than 20,000 species of animals, so that 13,000 of them became extinct .

Echinoderms and Cnidarians: Echinoderms and cnidarians are quite different in many ways. Echinoderms have a water vascular system consisting of a central canal ring that extends along each arm, through which water circulates for exchange and nutrition of gasses. Members of the phylum have a water vascular system that powers their multitude of tube feet. CONTENTS. The phylum chapter | 16 pages analysis of a new 18S rDNA data set indicates that are. The next characteristic of echinoderms is to move with ambulacral, namely the tubular legs with small holes that serve to suck. She did her M.Sc.

Although all living echinoderms have a pentamerous (five-part) radial symmetry, an internal skeleton, and a water-vascular system derived from the coelom (central cavity), their general appearance ranges from that of the stemmed, flowerlike sea lilies, to the wormlike, burrowing sea cucumbers, to the heavily armoured intertidal starfish or sea urchin. This symmetry is based on a five-part system where a central structure is surrounded by five equal parts. Other unique characteristics of echinoderms include: They can regrow lost limbs or body parts, such as internal organs.

Echinoderms are an exclusively marine phylum with four distinctive characteristics:Adult echinoderms are radially symmetrical, usually with a fivefold pattern, however, they are considered to be bilaterally symmetrical animals because they start off as bilateral larvae, such as the bipinnaria larva (sea star larva, left) and pluteus larva (brittle star larva, right) shown in Echinoderms lack respiratory and excretory systems.
