The slate pencil urchin, Eucidaris thouarsii, is a species of cidaroid sea urchins that inhabits littoral regions of the East Pacific Ocean.
Distribution and habitat
E. thouarsii is found in the East Pacific at depths of 0–45 m (0–148 ft), ranging from Baja California to Panama, as well as Cocos Island, Clipperton Island and the Galápagos Islands. The Galápagos, Clipperton and Cocos populations are now often recognized as a separate species, E. galapagensis, instead of a subspecies of E. thouarsii.
