Eucidaris galapagensis is a species of cidaroid sea urchin that inhabits littoral regions of the Galápagos, Clipperton, and Cocos.[1][2][3] It used to belong to the subspecies E. thouarsii to the slate pencil urchin, but is now recognized as its own species separated by the aforementioned regions.[3]
Diet
Like all urchins these are primarily herbivores, but feed on a wide range of invertebrates.[4] This species has a high nutrient absorption efficiency when it comes to the coral Pocillopora damicornis, but would require a large intake to make nutrient requirements.[5] Due to its high intake of coral, it reduces reef growth within the Galapagos.[6]
