Fin's Fish Guide
The Rockfish (Myliobatis goodei) is a saltwater fish of the family Myliobatidae that grows up to 125 cm.
Description
The southern eagle ray is an eagle ray of the family Myliobatidae from the western Atlantic. The species grows to about 1.25 metres wide and has a rhomboidal, wing-like pectoral disc with pointed tips and a long, whip-like tail. It 'flies' with powerful pectoral beats through coastal waters to about 130 metres. With its flat jaw plates it crushes hard-shelled prey such as shellfish, crabs and crustaceans dug from the sand bottom. Reproduction is ovoviviparous. On the tail are one or more serrated, venomous spines; a sting causes severe pain, so never step on a ray and keep your distance.
