Etymology: Chimaera: Named for the mythological creature composed of parts of multiple animals, referring to their odd mix of characteristics (See ETYFish); willwatchi: In honor of the “hard-working” fishers onboard the Sealord Corporation fishing vessel Will Watch, from which holotype was collected (See ETYFish).
Eponymy: Not a true eponym as this is named after a ship’s company – the ‘hard-working’ fishers on board the Sealord Corporation fishing vessel ‘Will Watch’, from which the type was collected. (Ref. 128868), visit book page.
