Etymology: Careproctus: Greek, kara = face + Greek, proktos = anus (Ref. 45335); laperousei: Named for the French Naval officer and seafarer J.F. Laperouse (Chevalier Jean-François de Galaup, comte de La Pérouse) (1741 - ca. 1788), who made a geographical expedition to the Pacific Ocean and discovered the Bussol Strait in 1787.

The bottom sediments in the box-corer sample at the place of capture included an upper layer of thin gray silt, dense greenish silt and coarse-grained black sand, with the ground from the Agassiz trawl greenish clayey silt interspersed with dense clay. The by catch of the trawl was mainly composed of the holothurian Peniagone sp., Sea feather Umbelulla sp., Scleractinia, sea anemones, sipunculids, polychaetes Travisia sp. and three types of Echiura (Ref. 123108).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00427 (0.00194 - 0.00940), b=3.19 (3.01 - 3.37), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.2 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
