Five big sharks that help keep our oceans healthy

You’re probably familiar with the great white shark, but how much do you know about these other big sharks: blacktip, tiger, sand tiger, galapagos, and whale? Those are just five of roughly 500 shark species found in our oceans. And they’re doing their part to keep the oceans healthy by keeping fish populations in check.

This Nat Geo WILD video about 5 Big Sharks That Rule the Sea is super informative with lots of excellent footage.
