I think that its that it eats clams, barnacles, snails, and sea urchins, sticks to rocks, lives in rocky areas of the seashore, and its stomach extends outside of the body to feed on prey larger than its mouth. That was its nutrition, activity (?), habitat, and adaptation anyways.
Some star fish are grazers- herbivores. Others are carnivores. Such as the Giant Crown of Thorns starfish of SE Asia. They creep over the reefs, destroying the living corals as they eat their way across. The Triton's Trumpet "snail" - a huge mollusc- is pretty much the only natural predator. As such, it is protected in many countries.
They are Omnivores

A Sea otters niche in the ocean is to keep kelp forests healthy. they do this by feeding on the animals that graze on kelp.
A sea turtle's niche refers to its "job" in the ecosystem. Different types of adult sea turtles have different niches. For example, some occupy the niche of being grazers on seagrass, and others eat jellyfish. Young sea turtles have a different niche than adults. An example of this is the green sea turtle. Young green sea turtles eat small sea animals, but adults occupy the niche of seagrass grazers. Generally, a niche is mostly determined by an animal's diet.
