Top 10 Animals with the Weirdest Behaviors

1. Cuckoo

   

   The cuckoo bird's approach to parenting is weird - they do not build a nest to lay their eggs in but do so in other birds' nests for them to look after their young. The cuckoo birds lay or drop their eggs into the nest of another bird, and once her eggs hatch, the female will attempt to drop the other species' eggs out of the nest.

2. Brown Trout

   

   Female Brown Trout fake an orgasm to encourage males to ejaculate prematurely. A fake orgasm makes the male think he's mated successfully when, in fact, he has failed. It's bizarre that fish have orgasms and can fake them.

3. Elephant

   

   Elephants are the largest land animals alive today. There are three recognized species: the African bush elephant (Loxodonta africana), the African forest elephant (Loxodonta cyclotis), and the Asian elephant (Elephas maximus). These are the only surviving members of the family Elephantidae. Extinct... read more

   They grieve, bury their dead, and may visit gravesites regularly.

4. Histiostoma Murchiei

   Histiostoma Murchiei is a parasitic mite found in the cocoons of earthworms. The females can create husbands from scratch all by themselves because they can lay eggs without fertilization. When the sons of a female grow up, she copulates with them, and the sons die shortly thereafter. Afterward, the female can lay many more eggs, producing around 500 long-lived females - these new baby girls are actually fathered by their dead brothers.

   I'm just going to say right now that I'm glad I'm human and not a newborn parasite destined to die by sexual intercourse at the hands of my own mother.

5. Flatworm

   

   They are hermaphrodites, meaning they can inseminate and be inseminated. To decide who will be the male, they perform penis fencing, which is an act of battle because both want to be the male. The winner is the one who pierces the skin of the other and becomes the male.

   Oh, and some of them have two penises. In the image I added, you can see this penis fencing ritual before mating (each has two penises - the white spikes on the undersides of their heads).

6. Pistol Shrimp

   

   Also known as the snapping shrimp, they spit bubbles at supersonic speed. The resulting sound is a sonic boom, and the shockwave from the bubbles is so powerful that it can break glass and stun larger fish.

   The temperature of the shockwave instantly reaches that of the surface of the sun! They shoot the bubbles and produce a loud snapping sound using one of their front claws, which is larger than half the shrimp's body. In the image, it's the long structure on the right end.

   They have a pistol-like feature made of two parts, with a joint that allows the "hammer" part to move backward into a right-angled position. When released, it snaps into the other part of the claw, emitting an enormously powerful wave.

7. Cattle

   

   Cattle (Bos taurus) are large, domesticated, cloven-hooved herbivores. They are a prominent member of the subfamily Bovinae and the most widespread species of the genus Bos. Adult females are referred to as cows, while adult males are called bulls.... read more

   Cows face the same two directions when they eat - either north or south. And scientists still can't say why. Why do cows hate facing east and west?

8. Human

   

   Humans (Homo sapiens) are the most abundant and widespread species of primate, characterized by habitual bipedalism and comparatively large, complex brains. These traits have enabled the development of advanced tools, culture, and language. Humans are highly social and live in complex structures, ranging... read more

   It's obvious we are the weirdest, but not in a bad way. For instance, we put things on ourselves, make and carry clothes and other devices to live on, walk on two feet, and actively manipulate the environment around us.

   While other animals do manipulate their environment or have degrees of self-awareness, we are the only ones who love fire. Chimps appear curious about it, and other animals usually detest it, but humans have a weird fixation with fire, which has helped us survive and thrive.

   Humans are so malicious and sadistic.

9. Adelie Penguin

   

   Their mating ritual is like a Rock 'n' Roll romance, literally.

   1. The male penguin rolls a stone to the feet of the female to make it clear that an engagement has been offered.

   2. The female gives her approval by responding with a belly-to-belly mating song.

10. Naked Mole Rat

    

    The naked mole-rat, also known as the sand puppy, is a burrowing rodent native to the Horn of Africa and parts of Kenya. It is closely related to the blesmols and is the only species in the genus Heterocephalus and the family Heterocephalidae. This species is known for its resistance to cancer, longevity... read more

    1. They can run as fast backward as they can forward, even when completely blind.

    2. They don't feel chemically-induced pain, so they wouldn't notice if you spilled acid on their skin.

    3. The queen mole rat pushes around other female mole rats to cause them stress, which releases hormones that make the other females unable to procreate.

    Mongoose

    

    A mongoose is a small carnivorous mammal found mainly in Africa and parts of Asia and southern Europe. It is known for its agility and speed, and it feeds primarily on insects, reptiles, birds, and other small animals. The mongoose is especially famous for its ability to fight and kill venomous snakes... read more

    Wolverine

    

    The wolverine, Gulo gulo, also referred to as the glutton, carcajou, skunk bear, or quickhatch, is the largest land-dwelling species in the family Mustelidae. It inhabits remote boreal forests and tundra across the Northern Hemisphere. Wolverines are known for their strength, endurance, and ability to... read more

The Contenders

13. Scorpion Fly

    

    The males have to spit a lot to survive because the female tries to eat the male during or after mating. To save his life, the male spits sticky saliva onto leaves that the female eats - this distracts the female so she doesn't eat the male.

14. Camel

    

    A camel is an even-toed ungulate belonging to the genus Camelus, known for the distinctive fatty humps on its back. These humps store energy in the form of fat, which camels can metabolize when food is scarce. Camels are native to arid regions of Asia and Africa and have been domesticated for thousands... read more

    The whole Camel Family spits when upset - camels, llamas, some alpacas, and guanacos. They spit stomach contents and saliva in the face of the annoyer.

15. Frigate Bird

    

    During the breeding season, males inflate their red throat pouch into a huge red balloon that can last for up to 30 minutes.

16. Sage Grouse

    

    The male (in the image) has two gular sacs that it inflates to attract mates. They look like silicone boobs.

17. Horned Lizard

    

    They squirt blood out of their eyes as a defense mechanism.

    I think there are other lizards that can do that too.

18. Llama

    

    The llama is a domesticated South American camelid. It has been widely used as a meat and pack animal by Andean cultures since the Pre-Columbian era. Llamas are closely related to alpacas, guanacos, and vicuñas, and they play an important role in the economies and traditions of Andean communities.

19. Alpaca

    

    They are from the camel family, so they spit too.

20. Zebra Finch

    

    Female Zebra Finches lay larger eggs when the mate is unattractive (most female birds lay smaller eggs when their mate is unattractive). The female Zebra Finch lays a larger egg to give her little ugly finch-ling a better start in life, with more nutrients and more room to grow, despite the father's imperfections.

21. Deer

    

    Deer are ruminant mammals that belong to the family Cervidae. This family is divided into two main groups: Cervinae, which includes species such as muntjacs, fallow deer, and chital, and Capreolinae, which includes elk, reindeer, roe deer, and moose. Most male deer grow and shed antlers annually, while... read more

22. Cat

    

    The cat (Felis catus) is a domesticated small carnivorous mammal. It is the only domesticated species in the Felidae family and is commonly called the domestic cat to distinguish it from wild felines.

    Cats can be house pets, farm cats, or feral. They are often valued for companionship and for... read more

    My cat is certainly a strange one.

23. Raccoon

    

    The raccoon, sometimes spelled racoon and also known as the common raccoon, North American raccoon, or northern raccoon, is a medium-sized mammal native to North America. It is recognized for its distinctive facial mask and ringed tail.... read more

24. Seagull

    

25. Africanized Bee

    

26. Hornet

    

    Hornets are the largest eusocial wasps and are similar in appearance to their close relatives, yellowjackets. Some species can reach up to 5.5 centimeters in length. They typically build large nests and are known for their potent stings and aggressive nest-defense behavior.

27. Falcon

    

    Falcons are birds of prey in the genus Falco, which includes about 40 species. These birds are widely distributed on all continents except Antarctica, although closely related raptors did occur there during the Eocene period... read more
