    Strongylocentrotus is a genus of sea urchins in the family Strongylocentrotidae containing several species. Pacific Ocean extending from Ensenada, Mexico to British Columbia, Canada. ^ a b Kroh, Andreas (2010). "Strongylocentrotus Brandt, 1835". WoRMS. World Register of Marine Species. Retrieved 2012-02-13.
    The Strongylocentrotidae are abundant marine echinoids with members living in the northern Pacific, northern Atlantic and the holarctic regions [ 26 ]. The group is comprised of four genera: Strongylocentrotus, Hemicentrotus, Pseudocentrotus and Mesocentrotus [ 28 ].

    Lee (2003) estimated that this species diverged from a common ancestor with Strongylocentrotus purpuratus, Strongylocentrotus droebachiensis, and Strongylocentrotus pallidus approximately 4.6–12 million years ago.
    H. pulcherrimus was placed sister to Strongylocentrotus species in all gene trees except ATPase6, ND4L and ND6. No single mitochondrial gene returned a topology corroborating with the N4Ds tree. The locations of S. purpuratus and S. fragilis were discordant between the MP method and BI and ML methods in the MA and M4 datasets.
    The Strongylocentrotidae has two deep-water species, S. fragilis and S. pallidus. Our inferred phylogeny provides evidence for a single radiation into the deep-water habitat. S. pallidus is typically found in lower depths [ 70 ].
