Etymology: Galeus: galeos, a small shark or dogfish according to Aristotle and others (See ETYFish); corriganae: In honor of Australian molecular geneticist Shannon Corrigan (b. 1982), “whose extensive molecular population and phylogenetic work on sharks has contributed toward an improved understanding of their alpha taxonomy and phylogenetic relationships” (she also captured some of the molecular data used in this description) (See ETYFish).
Eponymy: Dr Shannon Leah Corrigan (d: 1982) is an Australian molecular geneticist. [...] (Ref. 128868), visit book page.
