Animal Species:Black Rockcod, Epinephelus daemelii (Günther, 1876)
The Black Rockcod is a common New South Wales species but is rarely seen due to it's secretive nature usually found hiding in caves and under ledges. Found on coastal reefs, estuaries and deep offshore.
Standard Common Name
The Black Rockcod has also been called the Saddled Rock-cod, Black Cod and Saddletail Grouper.
The Black Rockcod can be recognised by a combination of features. These include the presence of canine teeth at the front of both jaws, posterior nostrils larger than the anterior nostrils and a grey to black background colour.
The species has small black spots and bars that are dark dorsally but fade ventrally. In larger fish these bars are often faint.
The Black Rockcod grows to at least 1.55 m in length
It occurs in Australia, New Zealand and the Kermadec Islands.
In Australia it is known from coastal and offshore reefs and islands from southern Queensland to eastern Victoria. It is also known from Elizabeth Reef, Middleton Reef, Lord Howe Island and Norfolk Island.

Distribution by collection data
The territorial nature of the Black Rockcod makes it vulnerable to spearfishing and angling. Declining numbers resulted in the Black Rockcod being declared a vulnerable species in New South Wales waters in 1984. It is illegal to sell Black Rockcod in the state of New South Wales.
