It is found in the East Pacific where it ranges from California (USA) to northwest Peru, including offshore islands such as the Galápagos.

Linckia columbiae can grow to 10 cm (4 in) across and varies greatly in colour and shape and even the number of rays.

The long cylindrical rays have blunt, triangular points that turn up slightly at the tip.

The colour is generally mottled grey and red and there are a number of rows of tiny yellow stars running longitudinally down each ray.

The animal remains stationary while the ray, using its tube feet for purchase, pulls and twists itself away from the disc until the tissue connecting the two breaks.
