This Fish Eats

 

In an extreme feat of parenting, some female cichlid fish carry their eggs and babies in their mouths for about two weeks. In this way, the young fish and fish-to-be are protected from predators in the outside world. The problem? Some get eaten by their own mothers.

A new study published Wednesday in Biology Letters not only reveals this cannibalism, but it suggests mother fish that eat their own young reduce cell damage caused by mouthbrooding, writes James Ashworth for London’s Natural History Museum.
