Short description
Morfologia | Morfometria
This large shovelnose ray is distinguished by the following characters: suboval disc, short and broadly rounded snout with nostrils partly covered with a large nasal curtain; ridges of small thorns present on mid-line of disc and shoulders; behind interorbital space is an ornate pattern of dark-edged bands without the distinct triangular or diamond-shaped marking (Ref. 114953).
A benthic species that occurs on continental shelf, mainly found on soft bottoms and seagrasses. Feeds on bottom crustaceans, worms, molluscs and small fishes. Produces litters of 2-5 pups. Maturity size of males at ca. 70 cm TL, females at 89 cm TL; birth size at 21-25 cm TL (Ref. 114953).
