Raja sp.

Tooth type: Crushing (female), Clutching (male).

All recent Raja spp. feed on bony fishes and invertebrates (mostly benthic crustaceans), living on the bottom, from shallow waters down to 800 m depth (Last et al., 2016a). The 24 extant species have TL values between 3.3 and 4.0 (Froese and Pauly, 2019). Ebert and Bizzarro (2007) gave a mean TL value of 3.76 for members of the genus Raja .

ORDER MYLIOBATIFORMES Compagno, 1973

Genus Aetobatus Blainville, 1816

Aetobatus arcuatus (Agassiz, 1843)

Tooth type: Grinding.

There are five extant species of Aetobatus with different diet habits, albeit all of them include bivalves (White and Last, 2016a). Aetobatus spp. can be between from 1 to 60 m depth (White and Last, 2016a). Four species have a TL of 3.6, but A. narinari (Euphrasen, 1790) has a TL of 4.2 (Froese and Pauly, 2019).
