The body of the shortfin mako (bonito) shark
is elongate but rather stout. The snout is long and pointed. The first dorsal

very small. This species is a deep blue or dark gray above and white below.

in warm and temperate seas; in the eastern Pacific from Chile to the Columbia
River, Washington, including the Gulf of California, but not in the tropics. |
Natural History: |
The diet of this onito shark includes fishes
and squid, often large ones. Whenever possible, the bonito shark takes its
food in one gulp. With its tremendous speed, it is unquestionably a dangerous
shark. Shortfin mako (bonito) sharks bear live young. |
Fishing Information: |
The shortfin mako (bonito) shark is one
of the larger sharks to inhabit California waters. By all accounts, it is
as dangerous as any shark, and it probably swims faster than most. The best
way to hook a shortfin mako shark is by trolling with a whole tuna, squid
or mackerel. You can also use lures, and chumming does help. Watch out, when
you catch one, because this is a dangerous fish that will not hesitate to
attack you or your boat. |
