Etymology: Thymichthys: Greek thymos (warty excrescence) and Greek ichthys (fish) in allusion to the warty protuberances on the skin of these handfishes;  verrucosus: Name presumably based on the Latin 'verrucosus' meaning full of warts, referring to the obvious warty nature of its skin (Ref. 82446)  More on authors: McCulloch & Waite.
