Giant trevally |
|
||
| Giant
trevally are robust and solid in appearance and can be recognised
by a steep and blunt head profile. They have immense power which
can be attributed to thick shoulders and midsections of muscle and
large almost paddle-like pectoral and tail fins.
Colouration can range from an almost white-silver to jet black. They may also exhibit a dusky golden hue all over the body, particularly on the fins. The giant trevally lacks a dark spot/colouration on the operculum (found behind the eye). In addition to the body colour of the giant trevally, striking striations and markings on the top section of the fish may also be present, particularly on the back. This is generally seen when the fish has a much darker back than the rest of the body, the contrasting markings showing up as light silvery lines. Black dots a few millimetres in diameter can also be found scattered all over the body, coverage can vary between none, sparse and widespread. Scutes (small sharp plates) exist along the
posterior portion of the lateral line and proceed along to the tail.
Caution is recommend when holding a giant trevally due to the sharp
scutes which can inflict significant pain. |
