How does a starfish feed?
Sea stars use suction in the tube feet for movement and feeding. When the prey is opened, the sea star pushes its stomach out of its body and into the bivalve, secreting enzymes that digest the prey’s soft body tissues. The liquefied bivalve is then absorbed into the stomach.
What is the habitat for starfish?
Habitat: Sea star habitats are highly variable; these animals can be found in all ocean basins of the world and at a large assortment of depths and bottom composition. They are benthic animals, which means that they live on the ocean floor whether they are in deep or shallow water.
Do starfish eat plant?
Starfish also eat plant matter. Some species are detritivores, eating decomposed animal and plant material. Others consume sponges and plankton. With more than 2,000 species, starfish and sea stars fill almost every ecological niche in the oceans.
How do starfish survive in their habitat?
The spiny skin’s colors act as camouflage to help the starfish blend into its environment. Some species have bright colors to scare off or confuse attackers. Instead of blood, starfish have a seawater vascular system that circulates nutrients and powers their tube feet, allowing them to move about their environment.
