Astropecten jonstoni

Astropecten jonstoni is a species of starfish that is classified within the Astropectinidae family that can only be found in the Mediterranean Sea. It prefers a habitat within sandy areas at depths between 3.2 and 39.3 feet. This species is unique in its shape, which highly resembles a star. Its upper side is typically clear with shades of greyish brown, turquoise-green, or light brown. It reaches a diameter between 2.7 and 3.1 inches, making it the smallest species in its family within the Mediterranean Sea. The arms of this species hold many short spines. Like other members of its family, this species buries itself in the sand, but it does not remain there during day, instead preferring to move about in the sun. It consumes its prey, mainly bivalve mollusks, by using its arms to move the prey to its mouth, which holds a number of spines that make the prey immobile.
