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 stripes that connect the tubercles. This creates an appearance of a grid made of interconnecting wires.
The skeleton is composed of many calcareous ossicles and spicules. They are located inside the layer of connective tissue. This skeleton supports the large disk.
Behaviour and diet
P. linckii is active in the daytime. 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.
