Question

Some members of this phylum keep their bodies clean through the use of pedicellaria

(pe-deh-sell-AIR-ee-uh). Its species have a system of interlocking calcium carbonate plates calledstereom. Many members of this phylum exhibit (*) pentaradial symmetry, and have tube feet calledpodia. Podia are found at the end of this phylum's main method of movement and respiration, the water-vascular system. Name this phylum of sea cucumbers and starfish, which has a Greek name that describe its members' spiny skin.

Answer 1

Phylum Echinodermata

Step-by-step explanation:

Members of this phylum can be seen at the sea beds and inter tidal -zones. They all live in marine habitat, thus they are not found in any other aquatic or terrestrial habitat. Their circulatory system is made up of vascular system of water. This provides mechanism for supply of nutrients, removal of wastes, for movements,and exchange of gases.

Their symmetry is radial, thus an imaginary longitudinal plane passing through the central body points divides them to many parts.

They can not swim, their vascular system of water aided their locomotion.

Answer 2

Definitely is ECHINODERMATA

Step-by-step explanation:

Echinoderms are marine invertebrates characterized by radial symmetry, they are animals that have 5 or more arms. This phylum includes, among others species, sea urchins, sea cucumbers, brittle stars, starfish, crinoids and sand dollars
