Echinoderms live only in the sea.
Yes Eventually echinoderms do live in water.
echinoderms
Echinoderms are mostly marine while arthropods dwell in almost all habitats.
Echinoderms are marine animals, which means they reside in the ocean. Echinoderms are found from the intertidal zone to the abyssal zone.
Echinoderms only live in oceans.
No not all Echinoderms have backbones like the starfish
Echinoderms are sea animals that live in salt water. There are five kind of Echinoderms, sea stars, brittle stars, sea cucumbers, sea urchins, and sand dollars. Echinoderms all are invertebrates and have internal skeletons.
Yes, all echinoderms have radial symmetry.
no, a lobster is a crustacean, not an echinoderm
Some do but not all.
all echinoderms live in salt water like in oceans and seas. They are in every ocean. Most adult echinoderms live on the ocean floor in salt water feeding on different sea animals. Many echinoderms can be found in tide pools along beaches or in oceans. the tide pools can support a variety of echinoderms and is changed every time the tide goes out.There are sea stars under the ice in the Antarctic and up in the north, Bering sea and around parts of northern Europe. Many are meat eating predators while some are grazers of algae.
The major difference between echinoderms and other invertebrates is that there are few examples echinoderms that do not live in ocean water and none live on land. There are examples of other invertebrates that live in both fresh and salt water and on land. Echinoderms also display radial symmetry as do the jellyfish and sea anemones. If you want to tag the one thing that echinoderms have that no other living invertebrate has, you would probably have to point to their water vascular system (see link). If you have the McGraw Hill science textbook for 6th grade then you are all set. Look on pages A40-A48.
