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 ) .

Biology     Glossary (e.g. epibenthic)

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.

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

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

Estimates based on models

Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 1.0078   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245 ). Trophic level (Ref. 69278 ):  3.5   ±0.37 se; based on food items. Resilience (Ref. 120179 ):  Very Low, minimum population doubling time more than 14 years (Fec=2). Fishing Vulnerability (Ref. 59153 ):  Moderate vulnerability (41 of 100).
