here are billions upon billions of creatures in the 7-mile deep oceans. Amongst them live the supremely graceful, beautifully evolved, super-predator and most feared animal on Earth — Carcharadon carcharias or great white sharks. In fact, there are 368 species of sharks that inhabit our oceans. Since the 1850s overfishing has changed life under the sea. Northern cod, North Sea skate, marbled rock cod of Antarctica and bluefin tuna are fished out, like the great whales before them and they are not recovering.
Sharks, rays and seahorses are on the road to extinction. East coast cod has declined 96 percent over the past 150 years. Sharks in particular have been brutally slaughtered for their fins, which fetch tens of thousands of dollars and then wind up in Asian soup bowls. Magnetic fishhooks are helping to save sharks, and just in the nick of time.

Kudos to scientist Eric Stroud and his company Shark Defense for helping to protect sharks.
