29 Sea Creatures with Superpower-Like Abilities
The Pirate Perch Has A Migrating Anus
Pirate perches are born with their anus in the usual spot, but as the fish mature, the anus migrates. By the time the pirate perch is an adult, the anus has moved up to underneath its chin. Presumably, its entire digestive tract is also shifting to keep up.
Pirate perches have another unique ability that scientists are trying to understand – and this ability is useful instead of just weird (and gross). They can disguise their chemical signature so that the insects that they feed off of do not know that the predator is nearby. Insects will happily choose to live in a pond containing pirate perch, blissfully unaware that they are about to become dinner.
