Tanner crab gets a lift from a methane seep off the B.C. coast

The curious scene was captured on video at a deep-sea station operated by Ocean Networks Canada, a federally-funded organization that supports marine science. A team of Canadian and U.S. scientists investigated what attracts the crabs – a migratory species – to this fizzy stretch of the ocean floor. After years of study, the scientists say the crabs are not there by chance, but to dine on bacteria that derive energy from digesting methane.
