Classification: Starfish are also referred to as sea stars because of their star-shaped appearance. They are a part of the phylum Echinodermata and are related to sand dollars, sea urchins, and sea cucumbers. Echinoderms are found in nearly all marine habitats and constitute a major proportion of the biomass.
Are Starfish alive?
How to tell if a starfish is alive or dead. Starfish get around using thousands of tiny tentacles, called tube feet, on the bottom of each arm. If you look closely at the underside of a starfish and see these tiny tentacles moving, then the starfish is definitely alive!
What kind of animal is a sea star?
Sea stars are invertebrates related to sea urchins, sea cucumbers and sand dollars, which are all echinoderms. Echinoderm means spiny skin—a reference to their hard, calcified skin, which helps to protect them from predators. Sea stars have rows of tiny tube feet extending from the grooved surface on their underside.

Starfish (or sea stars ) are beautiful marine animals found in a variety of colors, shapes, and sizes. The amazing sea creatures—part of a group of animals known as echinoderms—travel using their tube feet. They can regenerate lost limbs and swallow large prey using their unusual stomachs.
How do starfish have babies?
Reproduction. Both male and female sea stars hold their sperm and eggs in pouches at the base of their arms. They reproduce by free spawning, that means ideally the male and female release their eggs and sperm at the same time. The egg and sperm float until they meet up and the sperm is able to fertilize the egg.
