Shortfin Mako

Isurus oxyrinchus

Also known as Blue Pointer, Bonito Shark, Mako Shark, Mackerel Shark

Shortfin mako sharks are the undisputed speed champions of the ocean, utilizing a specialized heat-exchange system to keep their muscles warmer than the surrounding water for explosive bursts of speed. These streamlined predators cruise temperate and tropical open oceans worldwide, frequently leaping high out of the water when hunting or hooked. Their striking metallic blue coloration, crescent-shaped tail, and large, black eyes make them instantly recognizable pelagic hunters.

Capable of high-speed charges and powerful bites; maintain a safe distance if encountered in open water.
Why it is dangerous
Possesses immense speed, power, and razor-sharp teeth capable of inflicting fatal wounds if provoked or cornered.
How to recognize a risky encounter
Look for a highly streamlined, metallic blue body, a white underside, and a sharply pointed snout.
What to do
Never attempt to spear, hook, or closely approach; back away slowly if encountered while diving.
What to notice
Recognizable by its crescent-shaped tail fin, long slender gill slits, and dark blue back.
Support conservation
Support sustainable seafood choices and advocate for international bans on mako retention.
Responsible observation
  • Keep Distance: Never attempt to feed, touch, or closely approach these highly active pelagic predators.
  • Watch for Leaps: Be alert when boating in mako territory, as hooked individuals can leap high into vessels.
