Dusky Grouper Epinephelus marginatus

The Dusky Grouper (shown above with a scorpionfish) has two separate population groups: one in the eastern Atlantic from the Iberian Peninsula and Mediterranean south along the African coast and round into the southern Indian Ocean to Mozambique; the second population is in the southwestern Atlantic off southern Brazil and northern Argentina. It usually grows to around a metre long but can reach 1.5m. The fish are born female and breed as females; as they grow older, they become males.
