Strongylocentrotus fragilis is a species of sea urchin of the family Strongylocentrotidae.
Description and characteristics[edit]
This is a regular sea urchin, with a spherical test bearing the anus and top and mouth on the bottom. They are somewhat flattened, and of pale pinkish color with white spines. It is a deep-sea species, and they can occur in great number where food is abundant.
Habitat and range[edit]
This is an abyssal species, occurring at many hundred meters deep on the western coasts of the North America.[1] They are distributed throughout the continental shelf and slope, being most abundant in the 200-300m depth range.[2][3]
Taxonomy[edit]
It was first scientifically described in 1912 by Jackson.[4]
This species is often referred as Allocentrotus fragilis, and its taxonomy is still under debate.[1]
