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.

Biologie     Verklarende woordenlijst (bv. epibenthic)

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).
