Etymology: Typhlonarke: Greek, typhlops = blind + Greek, narke = numbness (Ref. 45335).
Eponymy: Lake Falconer Ayson (1855–1927) gave the holotype to its describer after the vessel ‘Doto’ trawled it up on a research cruise, of which Ayson was the leader. [...] (Ref. 128868), visit book page.

50 = 0.7502 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref.

回復力 (Ref.
120179): 低的, 最小族群倍增時間4.5 - 14 年 (Assuming fecundity<100).
Fishing Vulnerability (Ref.
