Sea otters eat them too. The sea star die-off may indirectly help otters by increasing the availability of high-fat, high-protein sea urchins.

Additionally, kelp forests protect coastlines from storm surge and absorb vast amounts of harmful carbon dioxide from the atmosphere.
In respect to this, are starfish becoming extinct?
Starfish are dying by the millions up and down the West Coast, leading scientists to warn of the possibility of localized extinction of some species. As the disease spreads, researchers may be zeroing in on a link between warming waters and the rising starfish body count. ORCAS ISLAND, Wash.

The egg and sperm float until they meet up and the sperm is able to fertilize the egg.Do starfish have hearts?

Starfish do not have blood in their bodies. Instead, they have a water vascular system that pumps seawater through the tube feet and throughout the body.

Like terrestrial forests, kelp forests absorb huge quantities of carbon dioxide that would otherwise be released into the atmosphere.How are sea otters important to humans?
Sea otters are a keystone species, meaning their role in their environment has a greater effect than other species. As such, sea otters also indirectly help to reduce levels of atmospheric carbon dioxide, a prevalent greenhouse gas, as kelp forests play an important role in capturing carbon in coastal ecosystems.
