to Newfoundland, and from North Africa to Norway and Iceland. It also inhabits
the Mediterranean Sea and the cool temperate waters of the southern Pacific.
A pelagic, oceanic shark, it has nevertheless been found near shore on
It is in same family as the white and the mako sharks and they resemble
each other. The snout is perfectly conical and ends in a point, and there
is a large, very prominent flattened keel on either side of the caudal
peduncle. It is easily distinguished from other sharks by its teeth, which
are smooth and have little cusps on each side of the base. It has a small
secondary keel than the white. The smaller keel is located beneath the
main keel but farther back on the tail. The first dorsal fin is farther
forward than on the mako or white sharks. Its anal fin is directly beneath
the second dorsal fin, whereas the mako's anal fin originates near the
midpoint of the second dorsal fin. It has a distinguishing white patch
on the free trailing base portion of the first dorsal fin.
It follows migrations of mackerels, herring, cod, bonitos, etc., which
is why it is often called mackerel shark, bonito shark, herring shark,
The porbeagle is reported to be an excellent sport fish and may leap when
hooked. The flesh is of good quality and texture and is said to taste somewhat
like swordfish. Fishing methods include trolling or bait fishing while
chumming. Baits include mackerel, herring, bonito, squid and other fishes.
They inhabit colder waters, which may account for
the fact that there are no recorded instances of it ever attacking humans.
The porbeagle is
warm blooded and ovoviviparous, having up to four pups measuring 19 ½ in
(50 cm) long at birth
