The colour of a starfish depends on its species and even on whether or not there are threats in its environment. Most species can change colour to blend in with their surroundings. Some starfish are naturally tan or dark brown, while others may be light pink or crimson red.
Cushion stars are a type of echinoderm that lives on coral reefs in the Atlantic Ocean. The colours of this species range from rusty brown to burnt sienna, red, and yellow. Sunflower starfish can also be different colours.
They can be purple, red, pink, or brown. The orange starfish is one species that always stays the same orange and red colour, with only small differences between individuals.
