Etymology: Lethenteron: Etymology not explained, perhaps lethalis (L.), lethal, or lethe (Gr.), forgetting or forgetfulness; enteron (Gr.) intestine, presumably referring to “degenerate and non-functional” intestine of adult L. appendix. (See ETYFish); mitsukurii: In honor of zoologist Kakichi Mitsukuri (1857-1909), Imperial University of Tokyo, who provided “free access” to specimens. (See ETYFish).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00126 (0.00057 - 0.00280), b=2.99 (2.80 - 3.18), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.1 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): Low, minimum population doubling time 4.5 - 14 years (Semelparous species, assuming tm (= tmax) > 4).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
