Wahoo
Acanthocybium solandri

Illustration: Bloom by Day
A long blue-green torpedo with a pointed beak of a snout and 24 to 30 narrow cobalt bars down its side — bars that vanish within minutes of the fish dying. One of the fastest fish in the sea; usually it is already past before you register it.
how to recognise it
- 24 to 30 cobalt-blue vertical bars running down past the lateral line
- iridescent bluish-green above, silvery sides, white below
- the bars fade fast once the fish is dead, so a fish on the deck looks plainer than one in the water
- a long slender body and a long narrow snout
don’t confuse with
- Spanish mackerel — the Spanish mackerel has wavy grey bars rather than many narrow blue ones, and a shorter snout
