A strange being resembling a severed human brain was found washed up on a beach in South Carolina, US. The photos, taken by Alexander Ilg, show an odd pink blob that puzzled the man and numerous Facebook users. While some commentators couldn't hide their disgust, others tried to guess what it is, with versions including "whale snot" and "sea alien".
According to many, there was nothing extraterrestrial about the thing's origin, calling it "sea pork", a member of the Tunicata family. They are marine filter feeders, who are often attached to the ocean's surface or even boats.
