Striped Marlin. Late each year, striped marlin migrate to the waters off the Baja Peninsula in Mexico.
You can snorkel/dive with them if you charter out good guides and boats.
These marlin hunt "bait balls" which are small schools of fish that get picked off by predators.
While the marlin attack from below, frigate birds and other birds attack from above.
From your boat, you scan the horizon for bird feeding frenzies. Then you race to them and dive in with your camera!
