Common thresher shark (Alopias vulpinus)<br />
Distribution: Worldwide in temperate regions.<br />
Habitat: Typic<strong>al</strong>ly offshore but does come inshore. Mostly taken in pelagic fisheries.<br />
Pector<strong>al</strong> fin description<br />
Dors<strong>al</strong> surface is slate grey or dark<br />
greyish-brown in color. The ventr<strong>al</strong><br />
surface is just as dark, with mottled<br />
white markings at the base of the<br />
fin. Long, slender from leading edge<br />
to trailing edge, curving sharply at<br />
the apex. Very sm<strong>al</strong>l white spot often<br />
(but not <strong>al</strong>ways) present at the tip of<br />
the apex, visible on dors<strong>al</strong> and ventr<strong>al</strong><br />
sides. Radi<strong>al</strong> cartilage is large and<br />
easily seen extending from the base<br />
towards the apex.<br />
Similar species: The bigeye thresher pector<strong>al</strong> fins (not included in this guide due to lack of sufficient<br />
samples for comparison) are suspected to be very similar in shape and coloration.<br />
