Etymology: Iago: Name of villain in Shakespeare’s Othello, because members of this genus have been a “troublemaker for systematists and hence a kind of villain” (See ETYFish); garricki: Patronym not identified but clearly in honor of J.A.F. (Jack) Garrick (1928-2018), New Zealand shark taxonomist and biologist (See ETYFish).
Eponymy: The name of this genus derives from Iago, the villain in Shakespeare’s play Othello. The authors say that this genus is “a troublemaker for systematists and hence a kind of villain”. Dr John Andrew Frank (Jack) Garrick (1928–2018) was a New Zealand ichthyologist with a specialization in elasmobranchs. [...] (Ref. 128868), visit book page.

背棘 (總數) : 0; 臀棘: 0. This species is distinguished by the following characters: snout long and narrow; preoral length 35.1% (34.9-38.7%) head length; eye large, its length 18.5% (17.0-24.1%) HL; gill slit rather short, first gill slit height 47.8% (31.4-51.6%) eye length; anterolateral teeth straight to slightly oblique, blade-like, with 1-3 broad, smooth distal cusplets; first dorsal-fin origin does not reach to the vertical line through the pectoral-fin base; caudal-fin ventral lobe is moderately developed in adults. Colouration: body generally grey, with faint dark edges on dorsal-fin apexes, more prominent in juveniles (Ref. 127459).
Body shape (shape guide): elongated; Cross section: angular.
A little-known tropical shark found on the uppermost insular slopes (Ref. 13563) at depths of 250-475 m (Ref.58048). Stomach contents of a specimen included small Macrouridae (Hymenocephalus sp., Nezumia sp., Ventrifossa spp.), crustaceans (Penaeoidea, Munidae) (Ref. 127459) and cephalopods (Ref. 244). Viviparous, placental (Ref. 50449). Caught irregularly by the small-scale demersal longline fisheries operating in deepwater. Utilized for its meat and fins, but of limited value due to its small size (Ref.58048).
