![]() The animal is known for its magic-like features and capabilities. The peripheral brains are effective at controlling the respective segments of the mosquito.Ĭuttlefish is a Cephalopod, meaning it belongs to the large mollusk sea animals such as squids and octopuses. The mosquito’s main ganglia brain resides at its head while the other brains are located at the abdomen and wings. The two insects rely on sensitivity to survive. Mosquitoes are pretty much the same as cockroaches. By the time you lift the slipper, the cockroach is already gone. I guess that’s why it’s super difficult squashing a cockroach using a slipper. For example, the insect’s response is 1/20th of a second. When it comes to cockroaches, one of the brains resides inside the skull, while the second brain is located at its back, near the abdomen.īecause of the duo of brains, cockroaches have amplified sensitivity. While the two optical lobes receive and process sensory information via the esophagus, the main brain controls the mantle, mouth, and movement. The brain is doughnut-shaped and very small in size relative to the body ratio. 80 percent is devoted to visual information. The fact that the brain’s dominance in functionality is optical shows how vision is vital to a squid. ![]() You may also like: 28 Keystone Species Examples in North America And lastly, the pleural coordinates the mantle cavity, which is used for respiratory.Ī squid’s brain comes in three ganglia parts: the central brain and two optic lobes. The cerebral is responsible for controlling limb movements, vision, and other sensory organs. The buccal controls the buccal cavity and the radula, both of which are used for feeding. The three brains include the buccal, cerebral, and pleural. Or you’ve seen some of them lugging around a wet yard.īut, did you know these soft-bodied mollusks have three brains?ĭespite being slow and prone to dehydration (hence the need to seek wet regions), snails have three ganglia pairs located at the esophagus. You must have encountered slugs in your backyard, crawling around your old wooden furniture. Octopus are among the smartest animals after humans. The octopus’ limbs are not only sensitive to light and color, but they’re also very responsive to touch and temperature. This allows for the processing of sensory inputs while amplifying senses. With more than 500 million neurons, only 30 percent of them are located at its main brain.Įven though each ganglion doesn’t require permission from the central brain, the neurons on the separate brains are effectively functional. The main brain resides at the head while the other brains are interconnected as fused ganglia, with each brain having its own set of neurons. The octopus has 9 brains, one for each tentacle and one at the head. Each brain has an independent neuronal ganglion that’s responsible for controlling the respective segment. The leech’s body consists of 32 segments.Įach of the 32 segments has its own brain. Leech is an annelid, meaning that it belongs to a category of animals with segmented bodies. In the following list we’re looking at animals with more than one brain. ![]() Most animals have one brains, some have more than one, and some animals have no brains at all. 10 Examples of Animals with Multiple Brains So let’s dive right in and have a look at 10 animals with multiple brains, then a few rare cases and couple of honorable mentions. There are several animals with more than one brain. This is because each ganglion functions autonomously. If you look at it in this manner, animals with such sections and hemispheres can be categorized as having multiple brains. These ganglia can be split up into many different parts that operate independent of each other. If you look at it anatomically, all animals have only one brain, but some species have sections (or hemispheres) known as ganglia, which function independently from the main brain. ![]() There are, however, several types of animals with multiple brains… so to speak. To clear up the confusion, it depends on how you look at it. A creature’s brain is a mass of nerve tissue that controls the rest of the body, the majority of animals have one brain.
