Etymology: Isistius: Etymology not explained, probably iso-, from isos (Gr.), equal; istius, from histion (Gr.), sail (i.e., dorsal fin), referring to its two similarly shaped and sized (and posterior) dorsal fins, a character Gill used to diagnose genus. José I. Castro, The Sharks of North America (Oxford University Press, 2011), suggests name may allude to the Egyptian goddess Isis, represented in statuary with her head veiled, or to the dark collar encircling throat of I. brasiliensis, “which could also suggest a veil over the head” (p. 145). This interpretation is rejected by the fact that Gill often used “istius” in the names of several genera distinguished (at least in part) by their dorsal fins (Acanthistius, Brachyistius, Caristius, Dichistius, Goniistius, Iniistius, Micromesistius, Nematistius) (See ETYFish)plutodus: ploutos (Gr.), wealth or abundance; odon (Gr.), tooth, referring to larger size of lower jaw teeth compared with congeners (See ETYFish).
