The fastest animals in the world

Among the most long-lived animals on planet Earth today are primarily a primitive species of jellyfish capable of regenerating themselves to the point of being considered, even, immortal.

Following closely behind are sea sponges and corals while among vertebrates are the shark, the Greenland whale and the orca Granny, all species that live, or have life expectancies, for as long as several hundred years.

In fact, the list of the longest-lived animals is quite long, but most of these animals are not very well known, partly because they are creatures we do not have to deal with. Let's find out which ten are the longest-lived.

There are many breeds of dogs in the world, each with their own characteristics that make them unique. Among the characteristics that can influence the choice of a dog is also their size, which is sometimes truly immense!

Many people love large dogs, which, however, due to their size, require special care and attention and obviously require a lot of space to stay fit.

Although dogs can be very tall, this does not mean that they necessarily have to be massive: some breeds are tall, slender and long-limbed, while others are inevitably robust and more imposing. Here are 10 of the world's largest dog breeds.

The work of the architect is not exclusive to humans as there are plenty of animals that can think and build objects or their own dwellings.

Animals that are 'architects' are all those that are capable of using materials and executing both temporary and permanent constructions. Just think of birds building their nests or beavers setting up dams. But not only that. 

Many animals build their dens while others make traps to catch prey that they then feed on.

Cats without hair or with tails and paws too short: here are some of the funniest and strangest cats in the world. Cats are incredible animals that fill our lives, giving us so much affection, making us laugh and smile with their habits so weird and at the same time adorable.

There are about 100 officially recognized cat breeds in the world but, unless we are talking about experts, it is really very difficult to know more than half of them.

If you are looking for a kitten with unique and very particular characteristics, below you can discover the strangest breeds of all.

In nature, many animals are often faced with the dangers posed by predators. Many animal species, when faced with danger, adopt curious strategies to avoid being preyed upon and to defend themselves: one of these strategies is to fake their own death. This strategy can be useful to ward off a distracted predator, to stall and escape, or to avoid direct attack.

This is a strategy that can help some animals survive, as some predators may be disinterested in an immobile prey, believing it to be already dead, and in this way the animal has a chance to escape.

Let's discover together five animal species that use this tactic!

Medical practices are evolving to give more and more space to the emotional component in healing. Pet therapy fits right into this new space. It is a therapy that uses companion animals, mainly dogs of specific breeds, as a support to regular traditional therapies.

Pet Therapy is used in so many areas: for example, it is useful in cases of hospitalized and long-term patients to improve mood and combat depression. It is also used to help sick children establish a better communication channel with doctors. Elderly care is also becoming very focused on pet therapy.

It has already been scientifically proven that pet therapy improves mood, lowers stress, and promotes better patient recovery, despite the fact that it is simply an accompanying therapy and not an actual cure.

We are surrounded by many myths and popular beliefs about cats that, moreover, do not always correspond to reality.

In this photogallery we explore 10 of these myths about cats, dismantling each false assumption one by one and instead revealing the truth behind the behaviour of our feline friends.

From the common belief that cats are nocturnal creatures, to the idea that they can only feed on milk, we will discover how they have been disproved by science. 

This photo gallery will surprise you with interesting facts about cats and help you learn more about these wonderful animals that share a domestic life with us. (source: cats.com)

Ticks can carry bacteria and parasites that can cause serious health problems in dogs. In this photo gallery we explore the signs and symptoms of the most common diseases transmitted by ticks to our four-legged friends.

You will discover how these parasites can affect dogs' appetite, body temperature, lymph nodes and joints. This overview aims to help you recognise early signs of these diseases in your furry friends, thanks to the information provided by 'pets.webmd.com'.

We hope that this photo gallery is informative and educational, enabling you to protect and care for the health of your dogs. Remember to always consult a vet for appropriate diagnosis and treatment.

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.

To hunt, sometimes it is not enough to be faster, stronger, or have the sharpest teeth.

In many cases, the winning weapon of predators turns out to be cunning: camouflage, knowledge of the prey's weak points, the ability to wait patiently - the most creative hunting methods require all of these.

Here are five cunning animal hunting methods.

There are animals with a very sensitive hearing capacity, able to perceive sounds at very high or low frequencies. There are insects that even have their hearing organs on their antennae. 

Humans perceive sounds within a range of 40 (very low) to 20,000 hertz. For comparison: bats are able to perceive frequencies of up to 300,000 hertz.

Let's find out together which other animals have the most developed hearing.
