Môi trường sống[sửa | sửa mã nguồn]

The dusky grouper is a solitary fish. It likes to live alone in rocks, at depths from the coast to 300 meters, but it's rare to find it below 60 meters. It has a barometric distribution, where the younger specimens are found near the coast and the older ones at the depths.

It normally has one cave considered as home and several other caves as temporary refuges. Its home has a minimum of two exits, and a size slightly bigger than the grouper, so no bigger animal can enter in. In case of biting attack or other force to extract it, the grouper opens its mouth, and the operculum spines wedge it inside the cave.

Nó có thể được tìm thấy ở the Mediterranean, the African phía tây coast and bờ biển của Brasil. It is rare in the waters of miền tây Indian ocean, Uruguay, Argentina, phía bắc of Pháp and the British Isles.

Reproduction[sửa | sửa mã nguồn]

It is a protogynous hermaphrodite, i.e. the young are predominantly female but transform into males as they grow larger. Reproduction normally takes place between the summer months.

Nutrition[sửa | sửa mã nguồn]

It feeds mainly on other fish, crabs and octopus. It is very greedy and one of the major predators in the Mediterranean sea.
