Info

Rhynchobatus laevis is a very large ray found off estuaries and in coastal bays.
It is often confused with Rhynchobatus djiddensis throughout its range and with Rhynchobatus australiae in Australian waters.

Dead rays are offered at fish markets, and for sport fishermen Rhynchobatus laevis is a strong fighting and desirable fishing prey.

Not an animal for a home aquarium due to its size and diet.

Synonyms:
Rhinobatus laevis Bloch & Schneider, 1801
Rhynchobatus yentinensis Wang, 1933
