It
is a yellowish brown to grey on the back with an almost metallic
sheen, blending into the silver grey sides. The membranes of the
anal and pelvic fins tend to be noticeable by their blackened appearance.
The
John Dory breeds in late spring and summer, with a rapid rate of
growth , so that by the second winter, individuals normally reach
25cm.
You
can find the John Dory sedately swimming among rocks and weeds and
shallow to moderate waters tend to be favored, although fish are
reported to depths of 200m. John Dory tend to be solitary fish.
The Dory's diet includes a wide variety of small fish, including
young of the Gadidae family, small herrings, sandeels,
etc. This fish is noted for its stalking abilities towards its prey
(which compensates for its lack of speed), which it then engulfs,
by use of its extendable (protrusible) mouth.
Whilst
having a range spanning from Scotland down to the Canary Isles and
Mediterranean, in the UK it is most likely to be encountered on
the southern and western shores.
