What are some similarities between sea stars and sea urchins?
both of them live in the ocean every where and they are echinoderms
Some sea stars are able to force open the shells of mollusks and bring their cardiac stomach (the sea stars) outside of its body into the shell of the mollusk and digest the mollusk. The sea star then brings its cardiac stomach back inside itself where further digestion takes place. Waste is excreted through the anus on the aboral side of the body. Yes, they "defecate"
Echinoderms move, feed and breathe with a unique water-vascular system ending in what are called tube feet. Sea stars use their tube feet to slowly pry open clams, mussels or other prey. Some sea stars can even evert their stomach between the two shells of a bivalve and digest the soft parts inside.
There are many different classes of starfish with many legs. Some of these classes include: Luidia maculata, Luidia ciliaris, Labidiaster annulatus.
What are the starfish's closest relatives?
The starfish's closest relatives are Brittle stars.
Sea urchins and sea cucumbers are also close relatives.
Where does food move in the sea star?
In sea stars, food moves through a unique digestive system that includes a stomach and a complex network of digestive glands. After capturing prey, the sea star extrudes its stomach out of its body and into the prey to digest it externally. The digested nutrients are then absorbed into the sea star's body through the stomach and transported to other parts via the coelomic fluid. This efficient system allows sea stars to feed on a variety of marine organisms, primarily bivalves.
