What are the characteristics of echinoderms?
Echinoderms (scientific name Echinodermata) are a major group of only marine animals. The name comes from the Greek word for “spiny skin”. There are about 7,000 species found usually on the sea floor in every marine habitat from the intertidal zone to the ocean depths. They have a wide variety of colours.
Are there male and female echinoderm?
The bulk of echinoderm species are diecious, meaning that there are male and female individuals. The type of reproduction that an echinoderm goes through depends on the species and the environment (Mulcrone, 2005).

Do echinoderms have bilateral or pentaradial symmetry?​

Although adult echinoderms possess pentaradial, or five-sided, symmetry, echinoderm larvae are ciliated, free-swimming organisms that organize in bilateral symmetry which makes them look like embryonic chordates. Later, the left side of the body grows at the expense of the right side, which is eventually absorbed.

Can echinoderms live in freshwater?​

Echinoderms are the largest phylum with no freshwater or terrestrial forms. Echinoderm environments must be marine, as in saltwater, for the echinoderm to survive. Within marine environments, the conditions echinoderms live in can vary greatly.
