insects do have a brain. they use it differently then us.
They have their antennaes and their brain
no there isn't lool
most insects have a rudimentary brain that can respond to stimuli, but with very little reasoning
A spider and an Insect have legs,heads,brain,lungs...
Short answer: jellyfish or various small insects. If you want a deeper answer, it depends on what you call a brain because a jellyfish has a nerve cluster which is technically a giant brain and the insects without brains have what we call: ganglia it is basically a brain just with no ability to think abstractly; it just controls basic functions and instincts.
Yes, every animal has some sort of brain. Even jellyfish have nerve clusters that act as a brain. Some small insects have ganglia that control essential autonomic functions and movement.
The ant Ants and Honeybees are considered the most intelligent of insects.
No. First, the brain and ears do not connect. Second, insects do not eat human brains. NOTE: Parasites in the intestines can have eggs travel through the bloodstream and by that route get into the brain.
An ant's brain is small and simple, with around 250,000 neurons. It functions differently from other insects because ants have specialized regions for processing information related to smell and navigation. This allows them to communicate and work together effectively in large colonies.
Mosquitoes like other insects have a tiny central nervous system which consists of a nerve ganglion rather than an actual brain. A ganglion can be considered to be equivalent to a very tiny brain.
