Violence is not the way to solve things. The bonobos uses sex for everything.
Bonobos use sex as greetings, a mean of solving disputes, making up for fights, and as a favors in exchange for food. They tongue kiss, engage in oral sex, mutual masturbations, have face-to-face genital sex and even have a strange “penis fencing” ritual! What a species!!! Amazing!!
Taste Urine before courtship
The male giraffe is an interesting animal that will use their head to nudge the rump of the female to induce unrination. Then, the male will taste it. If its good then he will start the courtship. ewww… dirty….
Tasting the pee
Dolphin: Not the third Hand
The dolphin has retractablepenis. And if that’s not cool enough, his penis is prehensile. And it swivels. In fact, a male dolphin can use his penis to explore objects just like a hand.
Male dolphins also have a very strong sex drive. It can mate many, many times in a day. Now here’s the bad news: male dolphins aren’t that much of a stud. The average time to ejaculation? 12 seconds.
They often try to hump inanimate objects and even other animals like sea turtles. Wow… thinking of sex all the time.
There are other strange mating behaviour of animals. Look up the articles below. Its real inteeresting for some.
Truly the stuff of Hollywood ‘animal horror’ flicks, the red-bellied piranha (Pygocentrus Nattereri), with its bulging eyes and razor-sharp teeth, have gained enough notoriety to rival the shark as the most-feared fish in the sea (aside from the fact that they don’t actually live in the sea, but rather in the rivers of the Amazon). Seen in a trailer of Discovery’s Animal Planet Series, River Monsters, a shoal of piranhas swarm and finish off half a duck carcass in a scarcely a minute. Definitely not something that you would like to find in your bathtub!
The scent of blood and the thrashing of an injured animal (or human!) in the water typically triggers off a feeding frenzy in the shoal, which results in several dozens or even hundreds of piranhas descending upon its hapless victim, completely devouring it in a matter of minutes. The piranhas can accomplish this scary but amazing feat mostly because their jaws of interlocking teeth tear easily into flesh, which they literally rip off and swallow without chewing.Once tearing off a chunk of meat, they move out of the way to make way for the next fish in line to get its bite. As a result the shoal efficiently demolishes off the unfortunate creature, leaving behind little more than skeletal remains.

Thankfully, such frenzies only occur when there is easy prey (old, sickly or injured animals) to be had, or when the piranhas have been starved and are really, really hungry. Under normal circumstances they rarely attack large, healthy animals (such as people), and mostly feed on other small fish and carrion. In fact, their role as scavengers(and not predators) is paramount to the Amazon’s ecosystem, as they very efficiently clean up any dead creature long before decay sets in, keeping the waters habitable for other marine life.
Contrary to what Hollywood would have us believe, piranhas are actually pretty wimpy creatures, considering that they live in the big bad (and very wild) Amazon. Originally thought to form shoals in order to effectively overwhelm and take down large animals, it turns out that the piranhas huddle together for predator defence instead; to take advantage of safety in large numbers, just like normal fish. And who would predate on the jaw-chomping, frenzy-feeding piranha? Just about anyone bigger than itself, it seems. Piranhas make tasty snacks for river dolphins, caimans, aquatic birds, and larger fish.
Looks like there’s always a bigger fish in the sea, isn’t there?
In past researches on dogs, it is almost believed that yawning in dogs is not a sign of tiredness but rather an indication that the dog is suffering stressing conditions from the surroundings. This is because yawning is able to increase heart rate and blood flow to the brain and helps to fill the lungs with oxygen. Thus, yawning helps a dog to energize its body and stays alert to respond to potential threats.
However, due to close socialization between human and our domestic canine buddies over thousands of years, man could affect how dogs behave and react overtime. A team led by Dr Senju, conducted an experiment and concluded that although at times, yawning in dogs is a response to extreme stress, the true reason for why contagious yawning is catching is not fully understood for now. However, a reason for dogs’ yawnings could be due to the fact that they have the capacity for a fundamental form of empathy towards human beings.
Am I tired? or am I not?
To further the research, the team created two conditions. For the first experiment, a stranger sat in front of the dog and calls its name. “We gave dogs everything: visual and auditory stimulus to induce them to yawn.” said Dr Senju. Under this condition, the stranger yawned once the dogs had made eye contact with them. As for the second condition, the auditory stimulus was taken off as a precaution to ensure that dogs were not responding to an open mouth. Out of 29 dogs from a wide range of dog breeds, 21 of them responded to the yawning, while no dogs yawned during the non-yawning scenarios.
“There are theories that seem to think that we used to transfer this information of ‘I am tired’ by yawning when we didn’t have language,” Joly-Mascheroni told LiveScience. In a way, humans could be indicating sleepiness to dogs. “It would be interesting to find out what other information we transfer to dogs or to any other animals that we are not aware of,” he added.
With great curiosity, I have conducted my own “yawning induction experiment” on my dog Happy. Like what was stated as the conditions, I called her name, waited for her to make eye contact with me and yawned with action and sound. Happy could not be bothered with me for the first time but responded upon the second trial!
Go ahead! Try yawning to your dog next time and see what happens!
For centuries, humans are believed to be the smartest amongst all the apes. Despite our 96% similarities in our genes, the chimpanzees are still inferior to us in many other mental functions.
But today, research has shown that young chimpanzees have better short term memory that an average man and have extraordinary ability to recall numerals. In this research, man and a young chimpanzee have to go through similar test procedures to examine and compare their ability to recollect numbers that they are only shown for a short while.

The picture above is a snapshot of Ayumu, the young chimpanzee doing the test.
Based on the results of tests, the younger chimpanzees do better than their mothers and also adult humans. The researcher, Matsuzawa said the young chimps’ ability resembled photographic memory, the ability in humans to retain a detailed and accurate picture of a complex scene or pattern. This talent — also known as eidetic imagery — declinez with age in humans, as it seems to do in chimps.

While out in the field at night, one occasionally can notice a gecko without its tail. This rather strange looking individual has autotomised its tail (which is part of its body part) and this process is scientifically known as autotomy.
Autotomy is defined as the ability to voluntarily shed a body part, typically along a predetermined breakage plane (Wasson et.al., 2002). This unusual behaviour is relatively widespread in certain animal groups and has been observed in rodents, salamanders, lizards, crabs, spiders and sea stars (Juanes and Smith, 1995). As different groups of animals have developed and maintained this behaviour, this implies that there must be strong selective benefits to it.

Why do animals choose to autotomise their limbs or body part? Several reasons have been proposed. Firstly, autotomy enables the animal to reduce injury to body parts. For example, certain species of crabs are known to break off their injured limbs. Secondly, this allows the animal to distract a predator and enable it to get away without being eaten. For example, certain lizards will often drop their tail when grasped in order to escape from predators.

However, losing a limb or a body part does not come without any cost and the animal may be at a disadvantage when its limb is temporarily absent. Firstly, the animal may suffer from a reduced ability to forage or defend. For example, when a crab loses a cheliped, it will be less capable in feeding and defending against potential predators. Secondly, the animal will also have to expend precious resources to regenerate the lost body part. This will come at the expense of growth and reproduction.
In conclusion, autotomy can be beneficial to the animal and may be important for survival in certain animals. However, it is not without any negative impacts to the animal.
