Animals are multicellular heterotrophic organisms, which are divided into 37-38 divisions, including sponges, annelids, mollusks, vertebrates to which insects belong, echinoderms, and finally craniums, which include the animals most famous to humans, namely: amphibians, fish, birds, reptiles, and mammals.
Curiosities of the animal world :
As we can expect, the diverse animal world is not devoid of curiosities and wonders that humans cannot comprehend of them, and every year biologists discover new organisms that open up worlds of wonder for which we can only say: Hallelujah who created the universe, create! Since it is a difficult task to take note of all the curiosities of the fascinating animal world, it will suffice to point out some of those curiosities.
Oddities of the mammal world :
Here is some information that may surprise you when reading about some species of mammals:
- Cats are able to bark just like dogs, all they have to do is push the air inside the vocal cords with more force than they usually do; to make a barking sound instead of meowing, due to the similarity of anatomical features between cats and dogs.
- Dogs and some other mammals such as mice can dream while they sleep, which is confirmed by researcher Stanley Koren in the book (Do Dogs Dream?)).
- Mice are ticklish animals; they make sounds of joy similar to human laughter when they are caressed in certain places on their body.
- The giraffe’s heart pumps blood with great force to be able to feed the brain, the heart of a giraffe whose head is 16 feet above the ground pumps blood with twice the force that a cow needs to reach the brain, and the blood system in the giraffe’s body is complex enough to ensure that blood does not rush to the head when bending, in addition, the skin of her legs is very tight; to prevent blood from collecting in the hooves separated by a distance of six feet from the heart.
- The milk of a female whale contains 50% fat, which is almost ten times more than in the milk of human females; therefore, the weight gain of young whales may reach 200 pounds every day.
Oddities of the ornithologist :
Here is some curious information about birds:
- The sex of a chicken can change to become a rooster in a spontaneous way; this is because the chicken embryo contains two genitals, and under the influence of sexual genes, the left organ develops to become an ovary while the right organ remains dormant, and in some cases, the ovary may be damaged as a result of tumors or cysts, so the dormant right organ begins to develop, and it is possible that it develops into a testicle that begins to produce male sex hormones, so the chicken turns into a rooster.
- Penguins are forced to gather in a colony-like crowd; to be able to survive the harsh Antarctic winter, and to avoid the death of birds that are on their limbs in the cold, Penguins are constantly reorganizing the positions of individuals; so that each penguin moves a small step by 2-4 inches, and thanks to these small steps a large-scale reshaping of the crowd occurs so that the Penguins that were on the limbs reach the center of the crowd, and this method of redeployment resembles the propagation of sound waves through liquids.
- The parrot is able to solve some language processing tasks as children do at the age of 4-6 years, and it can also understand terms, such as similarity, difference, and larger and smaller values, in addition to distinguishing numbers, contrary to popular belief that the parrot imitates only sounds.
- Some species of birds, such as the Arctic tern, set off on a round trip of 25 thousand miles every year without finding difficulty in navigation, and it is believed that birds use the property of magnetism inside them to determine their direction relative to the Earth’s magnetic field, and pigeons take advantage of the presence of some familiar landmarks on earth to be able to find their way home.
- The diameter of a typical bald eagle’s Nest is 1.5 M, and its depth is 1.8 M.however, a nest was discovered in Florida in the sixties of the twentieth century weighing 2 metric tons (2000 kg), with a diameter of 2.9 M, and a depth of up to 6 M. it is known that Eagles may live in the same nest for periods of up to decades, during which they add more twigs, branches, algae, feathers, and other nesting materials, which explains the large sizes that their nests reach.
Various curiosities of the animal world :
Here is some strange information about some types of animals:
- The southern cricket frog is able to jump to a height of up to 60 times its body length, which is similar to a human jumping up to the top of a 38-story building.
- Some fish species such as the Danio striped fish suffer from insomnia, which leads to them not getting enough hours of sleep, and studies show that if fish cannot sleep during the night, they will be restless and unable to learn as usual the next day.
- Scorpions glow with a blue light in the dark, thanks to the proteins found in their exoskeletons, where they convert ultraviolet light into blue light, and this blue light is a kind of defensive weapon that works together with pincers and poisonous glands that are at the end of the tail to scare their enemies and warn them to approach them.
- Crocodiles swallow large pieces of rock that remain permanently in their belly, and these rocks act as a kind of ballast or ballast; to help the crocodile dive.
- The length of the fruit fly’s sperm reaches 2.2 inches, which is the longest sperm in nature, which is larger than its body length of 0.11 inches, and it is also much longer than the length of the human sperm, which is up to 0.002 inches, and the sperm inside the fruit fly wraps around itself tightly so that its small body can accommodate it.
- The mouth of the Leech has three separate jaws; in each jaw, there are 100 teeth of small size, but they are very sharp, thanks to these teeth the Leech can make an incision in the skin and begin to suck blood, and ensure that blood does not clot, there are special channels between the teeth that secrete anticoagulant substances that maintain blood flow quickly, and also secrete narcotic substances that reduce pain in patients receiving treatment by leeches.
- The butterfly’s legs contain special taste receptors similar to those found in the human mouth, and the butterfly uses the receptors to taste the leaves of the trees on which it will lay its eggs, to make sure that they are edible, and do not contain toxins that can harm the larvae that will feed on these leaves after they emerge from the eggs.
