Leech: The interior structure of a leech is divided into 32 different segments, each of which has its own brain.
The leeches that I have driven several hundred miles to encounter are freshwater, bloodsucking, multi-segmented annelid worms with 10 stomachs, 32 brains, nine pairs of testicles, and several hundred teeth that leave a distinctive bite mark.
Silkworms have animal have 11 brains.
The brain, which serves as the silkworm's primary control centre, is situated in the centre of the head.
Leeches are small tiny animals that have founded to have 32 brains and these animals not only have 32 brains but many more interesting facts such as having more than one pair of eyes to be specific it has 5 eye pairs and a total of 300 teeth, as well as other features of leach, include it to have 10 stomach in total ...
Leech: Leech is an annelid. Leech's external and internal segmentation do not correspond to each other. If the internal body is examined, it can be seen that the body is divided into 32 parts or segments which have their own corresponding brain.
An octopus's brain-to-body ratio is the largest of any invertebrate. It's also larger than many vertebrates, although not mammals. Octopuses have about as many neurons as a dog - the common octopus (Octopus vulgaris) has around 500 million. About two thirds are located in its arms.
The sensory system of leeches is somewhat of a mystery, but includes five pair of eyes on the head, as can be seen in the cover illustration.
The mantis shrimp's visual system is unique in the animal kingdom. Mantis shrimps, scientifically known as stomatopods, have compound eyes, a bit like a bee or a fly, made up of 10,000 small photoreceptive units.
Snails have more teeth than any animal.
This is TRUE. A snail's mouth is no larger than the head of a pin, but can have over 25,000 teeth (but these aren't like regular teeth, they are on its tongue).
Icefishes of the family Channichthyidae has white blood.
Sea cucumbers have yellow blood due to a high concentration of a yellow vanadium-based pigment called vanabin. Some members of the phylum Annelida (segmented worms and leeches) have a greenish respiratory pigment called chlorocruorin.

Prasinohaema prehensicauda, found in New Guinea, is a green-blooded lizard with high concentrations of biliverdin, a toxic green bile pigment. Green blood is one of the most unusual characteristics in the animal kingdom—and the hallmark of a group of lizards in New Guinea.
Soon, we learned of the many myths surrounding the number of stomachs in the average Etruscan Shrew. Some believe the species evolved 800 stomachs, though it's difficult to imagine.
Babirusas are hogs that have two large canine teeth. These teeth can grow up to 8 inches long, sometimes growing right through the skin. Hippopotamus – Hippopotamuses have the largest teeth of any land animal.
Shark teeth are shed often, only to be replaced by a new set, several times during a shark's lifetime. Some species can shed upto 35,000 teeth in a single lifetime. The shape of the teeth depends on what a shark eats.
Several groups of mammals have decided to do without teeth altogether. The 10 species of Whales in the order Mysticeti, the 8 species of Pangolins family Manidae, and the 3 species of Anteaters in the family Myrmecophagidae and order Edentata have all given up on teeth completely and have none.
Answer and Explanation: Yes, there is in fact a small genus of copepod called the Cyclops that has only one eye. This tiny (smaller than a grain of rice) animals are found in water and all the species of this genus have only one eye.

You know how we (humans) have eyeballs? Well, owls don't. They have eye tubes or cylinders, rod-shaped eyes that do not move in their sockets as eyeballs do. Instead, owls have to move their bodies or heads in order to look around.
Two tubular, segmented hearts propel blood through the closed circulatory system of the medicinal leech and switch every 20-40 beats between two constriction patterns.
The Etruscan shrew has the smallest brain of all mammals. Its cerebral cortex is very thin, only 400 to 500 µm on average [16,70]. As in other mammals, the cortex of the Etruscan shrew is a cytoarchitectonically heterogeneous sheet of tissue.
Seeing: Earthworms have no eyes, but they do have light receptors and can tell when they are in the dark, or in the light.
