Anatomically, the human and animal bodies have several similarities and differences. For example, most animals have two eyes like humans. However, there are also animals that have more limbs than humans, for example the number of legs. There are animals whose legs are four, six, eight, even hundreds of feet. It turns out, not only feet, some animals have excess numbers in unusual body parts, for example the nose, penis, heart, and so on. Want to know what animals are like that? Here comes the review.
Snails have two noses
Most animals have one nose, but snails have a pair, aka two noses. Well, technically a snail doesn’t actually have a nose like most animals do. However, they also have their smell organs, the tentacles on their heads.ca snail has two pairs of tentacles. The pair of tentacles on the top of its head function like eyes, namely to detect light. Meanwhile, a pair of tentacles located on the side of its head functions to smell, like a nose. In addition, the tentacles also function as a sense of touch.
Lemurs have two tongues
While lemurs have an advantage in the number of tongues. They have two tongues. Reported by the Mom page, this primate animal that lives in Madagascar has two different tongues of function. First is the main tongue, which functions the same as the tongue of animals in general, namely to help them eat.
Well, under its main tongue, lemurs have one more, smaller tongue. The tongue is called the grooming tongue. This tongue is stiffer and they use it for grooming, aka to clean the bodies of other lemurs. Lemurs lick each other’s bodies with these tongues to remove dirt or lice from their bodies.
Octopuses have three hearts
Octopuses have an astonishing number of hearts. Reported by Science Focus, octopus has three hearts and that’s not without reason. Unlike humans and most animals, octopus blood does not contain hemoglobin which functions to bind oxygen. On the contrary, their blood contains hemocyanin.
The hemocyanin content makes octopus blood have a unique color, which is blue. But unfortunately, hemocyanin is not as effective as hemoglobin in circulating oxygen throughout the body. For this reason, octopuses need three hearts at once so that the entire body and their eight active tentacles can get enough oxygen for activities.
Sharks have two penises
Male sharks are unique in that they have two penises. Well, technically they don’t have two penises, but two claspers. The clasper itself is an organ used to insert sperm into the sex of female sharks. Despite having two claspers, sharks actually only use one clasper when mating.
Leeches have 32 brains
Well, of all, you could say the strangest is the leech. That’s because this animal has a brain that number 32! Well, technically, they actually have one brain. However, the leech’s body consists of 32 segments, each of which has ganglia.
Ganglia are collections of neurons that function to regulate body coordination. Each ganglia can organize its own segment. Hence, you could say that leeches have 32 brains. In addition, The Guardian said that leeches also have 10 stomachs and 18 testicles. Extraordinary! These are five examples of animals that have an unusual number of body parts. Very unique, huh! Can you imagine if our body parts are also in number like them?
