Animal Species:Tripletail, Lobotes surinamensis (Bloch, 1790)
As its common name suggests, the Tripletail could appear to have a three-lobed tail. This results from the rounded dorsal and anal fins that are posteriorly-positioned.
Standard Common Name
Triple-tail, Black Perch, Dusky Perch, Flasher, Jumping Cod
The Tripletail has distinctively rounded soft dorsal and anal fins. This characteristic gave rise to the standard name. The species has small scales extending onto the dorsal, caudal and anal fins and a head profile which becomes more concave with age.
The leaf-like juveniles are mottled with yellow, brown and black, whereas large adults are jet black.
The Tripletail is the only member of the family Lobotidae.
The Triple-tail grows to 1 m in length and up to 15 kg.
The species occurs in all tropical and subtropical seas.
In Australia it is known from tropical and subtropical marine waters.
The fish in the image is probably the most southern record of this species on the New South Wales coast .
