Sea Otters Are Ruthless Killers

This changes everything. Sea otters have been attacking and drowning baby seals for years, and we never knew until this shocking exposé published in Slate. Nineteen cases of sea otters fatally harming baby seals after attempting to mate with them were reported in 2010. Scientists confirm that this roughness typically occurs because male sea otters compete for mates, and when they finally get to one, they bite their faces. And sea otters aren’t the only ones with this disturbing track record—dolphins and penguins have also been known to engage in cringeworthy behavior. (Not so cute anymore, huh?)
