Pterasteridae is a family of sea stars in the order Velatida, consisting of eight genera.
== Description and characteristics == Pterasterids are primarily deep-water, and have an inflated aboral surface. Like many other members of the ordo Velatida, they have a hole in the middle of the central disc called "osculum", from which they can expel mucus for defending against predators.
