A huge skeletal hand has been found by a couple on a beach in Brazil's São Paulo, with social media users saying that it belongs to an alien. Marine biologist Eric Comin said that it belongs to a cetacean - an aquatic mammal including whales, dolphins and porpoises. Based on the decomposition, the ocean animal died around 18 months ago.
