Tag: Cloudy Grouper (Epinephelus erythrurus)

The Cloudy Grouper (Epinephelus erythrurus) is a relatively common, albeit shy, member of the Grouper family found in local waters.

Growing to a maximum length of around 45cm, the Cloudy Grouper is one of the more easily identified local species with an overall colouration that varies from pale to mid grey or olive green with a network of darker grey/brownish markings on the body and head.

The pectoral fins lack the lines or spots found on many Grouper species and there are also distinctive yellowish markings on and around the eye.

Unlike many of its local relatives, the markings on this species do not form distinct or broken vertical bars. Instead, the pale blotched ("cloud" shaped) markings between the darker lines are the most distinctive feature, and probably give rise to its common name.

Although inhabiting coastal reef areas, it is more common to encounter a Cloudy Grouper resting in a crevice at offshore sites such as Sail Rock.
