Do bugs have brains?

The insects' tiny brains, on average, have about 200,000 neurons and other cells, they say. By comparison, a human brain has 86 billion neurons, and a rodent brain contains about 12 billion. The figure probably represents a “floor” for the number needed to perform the bugs' complex behaviors.

What animal has 32 brains?

What animals have 9 brains?

Thanks to their nine brains, it seems that octopuses have the benefit of both localised and centralised control over their actions.


What animals has the best memory?

The new research shows that dolphins have the longest memory yet known in any species other than people. Elephants and chimpanzees are thought to have similar abilities, but they haven't yet been tested, said study author Jason Bruck, an animal behaviorist at the University of Chicago.

Does a fly have a heart?

The fly's heart is a 1 mm long muscular tube that runs along the dorsal side of the abdomen, and contains a number of intake valves. At the anterior end of the abdomen, nearest the fly's waist, the heart narrows and becomes the aorta, which travels through the fly's thorax and opens up in the head.
