Puffer Fish Video
Watch in amazement as this puffer fish avoids certain death by self inflating as it’s attacked by a river otter. The otter becomes confused and frustrated by the amazing self defense mechanism, giving up his snack and moving on as the puffer fish refuses to deflate.
It turns out this is a good thing for both of them as the puffer fish has a poisonous gall bladder, something that would kill the otter if it was to eat it.
