Blue Shark Highlights:
These sharks are as beautiful as they are dangerous. Blues have been known to attack
and harass divers. They generally live offshore, but can come near shore. The
blue shark is one of the most abundant species of sharks, but is also the most fished. It
is estimated that 10 to 20 million are killed a year.
Blue sharks are
viviparous.
Pups are born
after a 9- to 12-month
gestation period (or 9 to 12 months after fertilization). A litter of pups
consists of 4 to 82 pups.
