    Oxynotus bru-niensis is one of five extant species in the family Oxynotidae, all of which are readily identified by their triangular body shape, sail-like dorsal fins, and enlarged dermal denticles (Ebert et al., 2013; Finucci et al., 2016).
    Oxynotus bruniensis exhibits a simplified enameloid microstruc-ture, which we compare with previously documented enameloid microstructures of other elasmobranchs. Though subtle interspecific differences in dental characters are documented, neither overall tooth morphology nor histotype and microstructure are unique to O. bruniensis.
    Therefore, estimations of the relative bite force of O. bruniensis in the absence of functional data should not be disproportionally influenced by tooth histotype. Oxynotus bruniensis has a very narrow dietary breadth, exclusively reliant upon the eggs of other chondrichthyans for food (Finucci et al., 2016).
    Another trend in phylogenetic analy-sis of Squaliformes is that Oxynotus is consistently recovered in close phylogenetic proximity to the genera Somniosus, Centroscymnus, and Scymnodon in multiple studies but with exact relationships differing slightly (Shirai, 1996; Klug and Kriwet, 2010; Da Silva et al., 2018).
    Oxynotus centrina leaves a distinct semicircular bite mark, and although there are interspecific variations in tooth morphology (e.g. the size of distal heels on symphyseal teeth), the overall denti-tion and oral anatomy appears very similar to that of O. bruniensis (Guallart et al., 2015).
