Popular facebook group Nature isn’t always kind and cuddly. A study showed that sea otters will restrain baby seals and then begin copulation; sometimes drowning it during the 105-minute-long process. Even after the seal is dead, the otter will hang on to the carcass and continue to mate with it for up to a week. I read this post on "I fucking love science"-group on facebook. Is it really true sea otter rape baby seals to the death?
