Etymology: Ctenacis: From ktenos (Gr.), comb; akis (Gr.), point, referring to its comb-like posterior teeth (See ETYFish); fehlmanni: In honor of ichthyologist-herpetologist Herman Adair Fehlmann (1917-2005), Smithsonian Oceanographic Sorting Center, for “setting high standards for field treatment of shark specimens collected for study” (See ETYFish).
Eponymy: Dr Herman Adair Fehlmann (1917–2005) of George Vanderbilt Foundation, Bangkok, and the Smithsonian was primarily an ichthyologist but also an herpetologist. [...] (Ref. 128868), visit book page.

Inhabits the outer continental shelf (Ref. 30573). Known only from the holotype. The presence of a very thin-walled, large egg-case in each uterus of the holotype suggests that the species may be ovoviviparous, and presumably have had two young in a litter (Ref. 244). Experts classify this species as oviparous (Ref. 50449). Its large mouth, small teeth, and large pharynx with gillraker papillae might allow it to feed on very small invertebrates, according to S. Springer.

Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0078 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00288 (0.00112 - 0.00741), b=3.15 (2.92 - 3.38), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.37 se; based on food items.

लौटाव (Ref. 120179): बहुत नीचे, न्यूनतम जनसंख्या दुगनी समय अवलागत 14 महीने। (Fec=2).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (41 of 100).
