A Sea Lion Chase

In a remote cove on the Galápagos islands sea lions have recently started to hunt yellowfin tuna in response to dwindling fish stocks. The tuna are faster than the sea lion so they rely on teamwork. They corral the tuna into the cove with different sea lions, having different roles in the hunt. Working together they block the tunas escape until it tires and becomes stranded in shallow water.
