Floating 'Alien' Orb Spotted by Fisherman Off Australian Coast

A huge, floating orb — one that looks more like an alien object than anything typically found in the ocean — left a fisherman perplexed when he came across it in the waters off the coast of Australia. Fisherman Mark Watkins spotted the ballooned carcass about 30 miles (50 kilometers) southwest of Bunbury, Australia. Marine biologist Andrew David Thaler told National Geographic in 2014 that the bloat of a dead, beached whale comes from pent up gas released as the animal's internal organs and stomach contents decompose.
