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 on the 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.

Strongylocentrotus fragilis (pink) with some Strongylocentrotus pallidus (white).

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]
