Causes of Climate Change. Climate change is a long-term shift in weather conditions identified by changes in temperature, precipitation, winds, and other indicators.
Answer by Marcin Wojtkowski. Confidence votes 167. Most sea star (starfish) species are generalist predators, some eating bivalves like mussels, clams, and oysters; or any animal slow enough to be unable to evade the attack (e.g. dying fish). Some species are detritivores, eating decomposed animal and plant material, or organic films attached to substrate.
Starfish are marine invertebrates or echinoderms in the class Asteroidea. Scientists, therefore, prefer to call them sea stars. There are 1,800 to 2,000 species of sea stars that vary in size, color and other characteristics. We think of the sea star with five appendages, but some sea stars can have many more arms.
