Eucidaris tribuloides, the slate pencil urchin (named after slate pencil), is a species of cidaroid sea urchins that inhabits littoral regions of the Atlantic Ocean. As a member of the basal echinoid order Cidaroida , its morphological, developmental and molecular genetic characteristics make it a phylogenetically interesting species.
Radiols (spikes) of a "slate pencil sea urchin". They are a classical souvenir. This species is a large sea urchin, crapping in some specimens reaching over 8 cm in diameter, with spikes up to 10 cm.

Researchers from Reef Rescue transplant elkhorn coral to a new coral reef site in 2019. In the picture, the purple-spined diadema sea urchins appear at healthy levels, a good sign for reef growth.
Eucidaris galapagensis, commonly referred to as the slate pencil sea urchin, is a species of echinoderms in the family of Cidaroid. [1] This sea urchin lives in coastal areas in the Galapagos, Clipperton, and Cocos. The preferred substrate of these organisms is rocky, benthic environments that provide refuge. [2]

Slate pencil urchin (named after slate pencil) is a common name for several sea urchin species with blunt spines: Eucidaris, a genus with several tropical species, especially: Eucidaris thouarsii, an East Pacific species; Eucidaris tribuloides, an Atlantic species; Heterocentrotus, a genus with two Indo-Pacific species
Heterocentrotus are brightly colored tropical sea urchins with very thick spines that have given them the nickname "slate pencil urchins", named after slate pencil.. The genus consists of sea urchins with rounded (but slightly elliptical) test , with the peristome (mouth) located in the center of the oral surface (lower) and the periproct at ...
