starfish – Panamic Cushion Star
Appropriately, it is also called a knobby star. They can reach up to 18 inches in diameter, and feast on mussels and barnacles. They are considered a keystone species in tidepools thanks to the work they do to keep mussel populations under control. But it’s not without effort — it can take a starfish upwards of six hours to eat a single mussel. This beautiful species is found around the Gulf of Panama and the Pearl Islands, all the way up to the northern parts of the Pacific Ocean.

The 70 or so species within this order live in the deep sea, at depths between 330 feet to over 19,000 feet below.

starfish – Chocolate Chip Sea Star
Unfortunately this species is collected as a tourist trinket and for the aquarium trade and are being overharvested in some areas. Though it has few oceanic predators, it does have one serious predator, that is humans. The dark patterns are a way for it to look more dangerous, and it works as it has little predators. These sea stars actually provide a home on its surface for other species such as tiny brittle stars, shrimp, and juvenile filefish.
