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).
Eponymy: Dr Kakichi Mitsukuri (1857–1909) was a Japanese zoologist who first went to the USA (1873) and achieved doctorates from Yale (1879) and from Johns Hopkins University (1883). [...] (Ref. 128868), visit book page.

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=0.00138 (0.00062 - 0.00310), b=2.97 (2.78 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
營養階層 (Ref.
69278): 3.1 ±0.4 se; based on size and trophs of closest relatives
回復力 (Ref.
120179): 低的, 最小族群倍增時間4.5 - 14 年 (Semelparous species, assuming tm (= tmax) > 4).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
