Shark Week GIF of the Day: Blue Shark


The sleek blue shark sports a dark-blue dorsal fin and brighter hue of blue on its sides. It's known as a superior mariner across long distances, and one of its kind was even documented journeying from New York to the waters off Brazil -- about 3,740 miles.


Blue sharks are all over Earth's waters, inhabiting temperate, tropical and sub-tropical areas of every ocean.

If you're an anchovy, you need to keep a lookout for blue sharks, as they love to prey on schooling fish, though they will go after pretty much anything they think will sustain them. Mackerel, squid, sardines, and squid need to watch out, too, as do birds, seals and turtles. In general, they're voracious eaters that sometimes push away from the table just long enough to regurgitate some of their intake so they can eat a bit more.

Blue sharks aren't exactly the biggest sharks in the ocean, topping out at anywhere from 5 to 7 feet long and weighing around 70 to 120 pounds. The deepest they will dive is a bit more than 1,100 feet, which is still pretty deep indeed.
