Ophiocordyceps unilateralis is an entomopathogenic (it acts as a parasite and can kill or disable the host) fungus. It is known as the mind controlling fungi and in the 1st picture it can be seen growing out the head of a “zombie” ant in the Brazilian forest. It can control the behavioral patterns of the host it has attached onto. It takes control of an ant so it can move to an ideal location for the fungi to grow and spread its spores, after that it kills the ant.
