Echinus tylodes
is a species of sea urchin in the family Echinidae. It is white with rather sparse pink spines and is endemic to the eastern coast of North America including the Gulf of Mexico. E. tylodes has a sub-globular test that is about two thirds as high as it is wide and grows to a diameter of 10 cm (4 in).
It is often found around deep-water corals, sitting on the coral branches or around coral mounds among the remains of dead corals. Examination of the gut contents of this species showed small shells and the skeletons of hydroids…

Dazzling New Sea Urchin Species Described
Simon Coppard, a post-doctoral research fellow at the Smithsonian Tropical Research Institute in Panama and an Encyclopedia of Life Rubenstein Fellow specializing in echinoids often uncovers new species during his research. In 2006, he and a fellow scientist discovered and described Coelopleurus exquisitus, a previously unknown sea urchin species from New Caledonia in the South Pacific.

The oldest sea urchin…
Evolutionarily, Diadema setosum is considered one of the oldest of the known extant species in the genus Diadema.
Genetic analysis of the Diadema have placed D. setosum at a basal branch on a cladogram, having it as the sister group to all the other remaining members of the genus. Morphological analysis confirms this conclusion, adding weight to the concept of D. setosum being the most basal of the Diadema and possibly the oldest extant species in the genus.
