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).

Maturity: Lm ? range ? - ? cm
Max length : 52.0 cm TL (female)
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.
栖息于大陆架外缘。 (参考文献 30573) 所知仅来自正模标本。 那有 holotype 的每个子宫的外壁薄卵子大的情形显示出此鱼种可能是卵胎生的, 而且可能已经有二幼鱼在一胎.(参考文献 244) 专家分类如卵生的这一个种。 (参考文献 50449) 它的大嘴，小的齿与大的口裂内部及鳃耙边缘具乳突可能允许它觅食最小型无脊椎动物, 根据 S. Springer。
