The red-knobbed starfish (Protoreaster linckii), also known as the red spine star, African sea star,[1] and the African red knob sea star,[2] is a species of starfish from the Indo-Pacific.[3][4]
Description
P. linckii grows to a maximum diameter of 12 in (30 cm). It has numerous tubercles located along its five arms. These tubercles are bright red and extend upward from the arms. It has a gray body with red stripes that connect the tubercles. This creates an appearance of a grid made of interconnecting wires.[5]
The skeleton is composed of many calcareous ossicles and spicules. They are located inside the layer of connective tissue. This skeleton supports the large central disk.[6]
It is distributed in the western Indo-Pacific[7][8] in locations ranging from shallow tidal pools to reefs up to 100 m (330 ft) deep.[9]

Behaviour and diet
P. linckii is active in the daytime.[10] It is a popular aquarium specimen, but is considered incompatible with many other invertebrates, as it will eat soft corals, sponges, tube worms, clams, other starfish, and alike.[11]
It is also a heavily fished species for curios trade.
