Most of them are marine while a few are fresh water forms. Body is cylindrical, asymmetrical or has radial symmetry.

Numerous molluscs also live in freshwater and terrestrial habitats They are highly diverse, not just in size and in anatomical structure, but also in behaviour and in habitat. a mantle with a significant cavity used for breathing and excretion, the presence of a radula (except for bivalves), and the structure of the nervous system

The phylum contains about 7000 living species. Most echinoderms are able to reproduce asexual and regenerate tissue, organs, and limbs; in some cases, they can undergo complete regeneration from a single limb. Geologically, the value of echinoderms is in their ossified  skeletons, which are major contributors to many limestone formations, and can provide valuable clues as to the geological environment

Unlike other bilaterals, they are aceolomates , and have no specialised circulatory and respiratory organs , which restricts them to having flattened shapes that allow oxygen and nutrients to pass through their bodies by diffusion . The digestive cavity has only one opening for both ingestion and excretion as a result, the food cannot be processed continuously.]]> 2018-04-17 16:09:46 UTC https://padlet.com/amleone20/vkkuh1tyf5kj/wish/252648080 amleone20 https://padlet.com/amleone20/vkkuh1tyf5kj/wish/253472739 2018-04-19 15:13:11 UTC https://padlet.com/amleone20/vkkuh1tyf5kj/wish/253472739
