USA’s NOAA (National Oceanic and Atmospheric Administration) is currently advising folks not to snap selfies with seal pups – not because you are going to get mauled by a very angry mother seal, but rather, seals do happen to have powerful jaws even when they are pups, and snapping selfies could stress them up, and they might just actually make a (literal) meal out of your limb in the process.
Not only that, should you be snapping a selfie with a seal pup and its mother returns, chances are the mother seal will abandon its pup for good by fleeing because it fears humans, and that would in turn leave the pup as helpless, and it would not stand a very good chance at reaching adulthood.
