#13: Brainless Bees
In the world of insects, there’s a surprising diversity in neurological setups. While some insects do indeed have brains, others employ a distributed nervous system to process information and make decisions. In these species, instead of a central brain, clusters of ganglia located throughout their body work in unison to control various functions.

This decentralized approach allows them to exhibit remarkable behaviors even when certain body parts are removed. For instance, as this person describes, a decapitated wasp trying to consume its own head. In the absence of its brain, the wasp’s remaining nervous system can still execute basic instinctual actions, sometimes resulting in peculiar and seemingly nonsensical behaviors that continue to astonish scientists and enthusiasts alike.
