Meet the blue shark (Prionace glauca), a deepwater denizen of tropical and temperate oceans the world over. You can find it as far north as Norway and as far south as Chile.

Fully grown males can reach a bit more than 9 feet (2.7 meters) long, a bit stunted alongside the females, which can top 10 feet (3 meters). They'll cruise anywhere from the surface, especially in cooler seas, to about 1,150 feet (350 meters) down.

This shark with the wide-eyed, slightly panicked look and slender frame is aces-up for long-haul journeys. Its migratory ways can take it from New England all the way down to Brazil.

Squid, octopus, lobster, shrimp, crabs -- blue sharks aren't terribly picky about their dining fare.

Furthermore, they know a thing or two about giving their species a chance. They give birth to live young and are known for their large litters: more than 100 pups, in some cases!

The slender fish have more to fear from us then we do from them. They're not much of a threat to humans -- implicated in just a handful of attacks over hundreds of years -- but by contrast are frequent victims of the fishing industry.
