होलोसैफली (किमाइरस) (chimaeras) > Chimaeriformes (Chimaeras) > Chimaeridae (Shortnose chimaeras or ratfishes)
Etymology: Hydrolagus: hydro-, combining form of hydor (Gr.), water; lagos (Gr.), hare, i.e., “water rabbit,” probably referring to three pairs of tooth plates, which tend to protrude from the mouth like a rabbit’s incisors (See ETYFish); bemisi: In honor of ichthyologist William E. Bemis, now at Cornell University, “longtime mentor and friend, and a leader in ichthyological research” (See ETYFish).
Eponymy: Dr William E Bemis is a vertebrate anatomist, currently Professor of Ecology and Evolutionary Biology at Cornell University, the university that awarded his first degree (1976). [...] (Ref. 128868), visit book page.

Estimates based on models

Preferred temperature (Ref. 123201): 5.4 - 9.5, mean 7.1 °C (based on 125 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00437 (0.00215 - 0.00887), b=3.05 (2.87 - 3.23), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.9 ±0.6 se; based on size and trophs of closest relatives

लौटाव (Ref. 120179): निम्न, न्यूनतम जनसंख्या दुगनी होने का समय 4.5 - 14 वर्ष। (Assuming Fec <100).

Fishing Vulnerability (Ref. 59153): High to very high vulnerability (67 of 100).
