Hybrid animals are the result of crossing organisms belonging to two different breeds or species. Hybrids are born between species that are quite similar, from a biological point of view, so as to be able to overcome all reproductive barriers.
These matings occur very rarely in the wild, although the two species share the same habitat.
The story, however, changes when man is involved, who for utilitarian reasons or for having randomly approached two different species, has given way to some very special hybrid animals: some are very famous, others a rarity.
The strength of an animal is not only measured by how mighty it is or by its muscles: another fundamental factor is the power and pressure of its bite.
It is not only the teeth or jaws that determine the power of a bite, but also the closing jerk. To make the bite estimate, scholars used the occluder, and then carried out simulations, certainly safer, on the computer, based on studies and knowledge of the physical structures of the animals taken into consideration.
Here is an estimate of the most powerful bites in nature: the force is calculated in psi, i.e. the pressure that occurs when an area of 1 square inch is subjected to 1 pound of force.
If you are one of those people who always seem to be the favourite target of these pesky insects, then this photo gallery might offer you some interesting answers.
Mosquitoes are blood-hungry creatures that are able to locate their prey through a combination of biological and behavioural factors. In this photogallery, we explore six surprising reasons why you might be the mosquitoes' preferred choice, reported by the Houston Methodist.
Through informative insights, we will uncover genetic characteristics, scents, daily habits, and more to understand what makes mosquitoes attracted to you over someone else. Prepare to be amazed and gain greater awareness of this annoying phenomenon.
Many of us have experienced the pleasure of receiving affectionate licks from our four-legged friends, but it is important to know that this gesture is not always a sign of love and gentleness.
Today we will explore different scenarios in which dog licking behaviour could have different meanings. Whether it is to show affection, or to express a situation of discomfort, there are many different motivations behind this gesture. Dogs communicate with us through their body language, and their licking can be a valuable indicator of their mood and intentions.
We will learn how to correctly interpret the language of dog licking and understand when it might be appropriate to intervene or respond accordingly.
One of the most fascinating curiosities about animals concerns the following question: are there species that can survive in space?
Apparently, the question is answered in the affirmative. This species does exist and it would be the tardigrades. Very special animals of their kind, with such unique characteristics that they are, at least as far as we know so far, the only species that can survive the extreme conditions in space.
Tardigrades are in fact very hardy and are able to withstand very harsh environments with extreme temperatures.
As with dogs, there are many differences in size (and more) between the various cat breeds. The FiFe Federation Internationale Feline recognises 41 breeds.
Some felines reach considerable size, sometimes weighing more than 10 kilograms, particularly male specimens.
Large cats are often chosen for their impressiveness and majesty, and sometimes their thick coat adds to their size: here are some of the largest cat breeds.
