Meanings (ES + gloss)
equinodermo
An animal of the phylum Echinodermata, comprising radially symmetric, spiny-skinned marine animals including seastars, sea urchins, sea cucumbers, crinoids, and sand dollars.
Comparatively few additions were therefore made to the previously known Echinoderm-fauna of Brazil, only a single species, a Leptasterias, being with certainty new to science.
Many echinoderms are still bilateral as larvae, and swim freely in the ocean like baby fish.
