Etymology: Atlantoraja: Greek, atlantes = having the strength of Atlas, the god that supported the pillars of the universe in the Greek mithology + Latin, raja = ray (Raja sp.) (Ref. 45335).

Max length : 132 cm TL macho/indeterminado; (Ref. 57911); common length : 45.0 cm TL macho/indeterminado; (Ref. 6077)
Oviparous. Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205). Eggs are oblong capsules with stiff pointed horns at the corners deposited in sandy or muddy flats (Ref. 205). Egg capsule measures 92-103 mm long and 72-80 mm wide (Ref. 41249). Utilized as fishmeal (Ref. 6077).

Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205).
