There are around 2,000 different species of sea stars, and they come in a range of colors, including pink, which help them camouflage or scare off predators. One can find sea stars living in oceans all over the planet, from tropical habitats to the cold seafloor. Marine scientists have adopted the challenging task of renaming these charming echinoderms "sea stars" instead of the once-common starfish.
