OK I am going to go with a Hamish type question..see how you get on with this one.
I am a long, thin, perch-like commercial food fish & I belong to the Gempylidae family.
I am found in the seas of the Southern Hemisphere.
In Australasia as I am known as a barracouta although I am not related to the barracuda.
I can grow up to 79" long and weigh as much as 13 lb.
In South Africa what is my name & which language does it come from?
