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.
Some leeches also possess 10 stomachs and nine pairs of testicles (all leeches are hermaphrodites, with both male and female sex organs). Yet leeches are far from the only living things with more organs than you might expect.
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.
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.
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).
Spiders usually have eight eyes (some have six or fewer), but few have good eyesight. They rely instead on touch, vibration and taste stimuli to navigate and find their prey.
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 ...
Thanks to their three mandibles with some 300 teeth on their anterior muscular sucker, they easily grab to tissues and by secreting their saliva containing numerous powerful enzymes, such as hyaluronidase, collagenase and inhibitors of platelet aggregation and coagulation, like hirudin, allow blood sucking.
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 rest are in the doughnut-shaped brain, which is wrapped around the oesophagus and located in the octopus's head.
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.
Cows have seven stomachs for a reason. The rumen, reticulum, omasum, and abomasum are the four compartments of a cow's stomach, and they are divided into four groups. Because the grasses and other roughage that cows consume are difficult to break down and digest, cows have specific chambers in their stomachs. ...
Given all the brainpower they ostensibly have, shouldn't octopuses rule the world? Not quite. Although they have a central brain and eight separate ganglia, or mini-brains, their nervous systems are wired entirely differently from most vertebrates, including mammals like humans.
The three brains of the adult male giraffes weighted respectively 722.7, 766.1 and 770.4 g, with a mean of 753.1 ± 15.23 g (Table 1). The body weights were similar with an average weight of 703.3 ± 50.4 kg.

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.
Icefishes of the family Channichthyidae has white blood.
The blackfin icefish, an Antarctic species also known as the Scotia Sea icefish, has been discovered to have white blood, making it the only known vertebrate on Earth without red blood, according to Quanta magazine(Opens in a new window).
The opabinia's most unusual characteristic was its head - it had 5 eyes, and a long, striped proboscis that resembled a vacuum cleaner hose or an elephant's trunk, with a claw-like structure at the end. Scientists aren't sure if the opabinia had any limbs, aside from its strange proboscis.
The tuatara has a third eye, as do some other reptiles. But this adaptation has been lost in the radiation into later orders such as crocodiles, birds, and mammals, although remnants of this organ can be found in most of these. The third eye, then, represents evolution's earlier approach to photoreception.
Did anyone know that some animals have blue blood, especially when it is exposed to oxygen? Can you guess what animals might have blue blood? Lobsters, crabs, pillbugs, shrimp, octopus, crayfish, scallops, barnacles, snails, small worms (except earthworms), clams, squid, slugs, mussels, horseshoe crabs, most spiders.
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.
For example, the monarch butterfly has. an impressive 12,000 eyes.
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.
