An astonishing school of hammerhead sharks surprises divers at Darwin's Arch in the Galápagos Islands in this majestic video from the BBC's Mission Galápagos series. In an article at Wanderlust, Mission Galápagos host and animal biologist Liz Bonnin lists this adventure as one of her "most amazing wildlife experiences":
The hammerheads come from all different directions and gather, swim around each other in big circles in a wonderful sort of balletic association. At the very centre of this big mass of hammerheads are the oldest, most mature females. The younger sharks swim around them. When the males come in to mate, they’ve got to weave and wind their way through this mass of hammerheads, so only the strongest, fittest males will get to mate with the females in the centre.
We are only just beginning to understand the purpose of this mass congregation, so the more scientists dive down there, the more they’re understanding its importance. It’s a very special place, and a very important behaviour, that needs to be protected. The Galapagos is one of the last jewels of this blue planet of ours. It really needs extra protection of ours oceans to make sure that that doesn’t disappear for ever. It was extraordinary.

You can do all the pre-workout stretching in the world, but that doesn’t mean you’ll escape stiff muscles and nagging pain after a particularly grueling gym session. When those knots and their accompanying aches and soreness start barking, your options usually boil down to either a deep tissue massage or just grinning and bearing it. […]
