In Panama this species was collected southwest of the point of the Azuero Penninsula (USNM 21078; Centroid Latitude: 7.2056, Centroid Longitude: -80.9167), eastern Pacific, by the R. V. Albatross, from a depth of 333 m.

Toxobrissus pacificus A. Agassiz, 1898 (transferred to Brissopsis)
Brissopsis pacifica isa deep sea burrowing sea urchin found in the Eastern Pacific on the coasts of Panama, Costa Rica, and Southern California, even near depths of 900m at the lower boundaries of the Oxygen Minimum Zone on California coasts (Alvarado et al., 2010, Gibson and Atkinson, 2003). They live in naturally low dissolved oxygen and low pH waters, and using otter trawl data from 2003 - 2013 in Southern California Bight, an analysis by Sato et al. (2016) showed that their depth distribution and population density have not changed significantly within that time period. However, their distribution and density do seem to be negatively correlated with the Multivariate ENSO Index (MEI), meaning on stronger El Niño years their density decreases and they move to shallower depths(Sato et al., 2016).
Brissopsis pacifica is a species of sea urchins of the family Brissidae. Their armour is covered with spines. Brissopsis pacifica was first scientifically described in 1898 by Alexander Emanuel Agassiz.[1]
