We published our cannibalism paper two years ago: nationalgeographic.com/anima… This is our follow up study: micropublication.org/journal…

Why these fish moms cannibalize their babies

Some African cichlid fish raise their young in their mouths—and snack on them. Now, scientists may have figured out the reason.

Stress is warping these fish brains

It is not some secret that stress can be bad for animal brains, and social stress itself can lead to a build up of oxidative stress. This imbalance of free radicals and antioxidants damages the cells...

Medal count per country corrected for population size (total number of medals divided by population size). Interesting ranking!

ALT Medal count per country corrected for population size (total number of medals divided by population size). Interesting ranking!

These mother fish eat some of their offspring to maintain strength, study finds | CBC Radio

Researchers hoping to learn why African freshwater cichlids carry newborn babies in their mouths discovered something even more bizarre: they devour some of the young offspring in the process.

Social rank, color morph, and social network metrics predict oxidative stress in a cichlid fish

Living in a social hierarchy can be stressful even for those on top. While past work has established the stress involved in being a low-ranking member of a
