(Linnaeus, 1758)
The pencil sea urchin (Heterocentrotus mamillatus) lives in the shallow water (up to about 10 meters) of coral reefs. The body grows up to 8 cm (without spines).
The spines reach a length of up to 12 cm. Stylose sea urchins move with their suction feet, which are located on the underside of the body, and can climb amazingly well.
The primary spines are brownish in color and may have white bands at the ends. There are also specimens with reddish spines.
There is a hint that the shrimp Gnathophyllum americanum lives on the sea urchin.
