Teleostei (teleosts) > Ophidiiformes (Cusk eels) > Bythitidae (Livebearing brotulas)
Etymology: Parabrotula: Greek, para = the side of + Latin, brotula, -ae = little, bud, shoot (Ref. 45335); tanseimaru: Named after R/V Tansei Maru.
Eponymy: ‘Tansei Maru’ is the name of a research vessel, owned by the Ocean Research Institute, University of Tokyo (now Japan Marine Science and Technology Center), which was responsible for collecting the holotypes of the goby and false brotula. (Ref. 128868), visit book page.

Estimates based on models

Preferred temperature (Ref. 123201): 0.7 - 16.4, mean 8.5 °C (based on 34 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.8750 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00813 (0.00246 - 0.02688), b=2.92 (2.67 - 3.17), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.0 ±0.00 se; based on food items.

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
