How did a female crocodile reproduce on its own?

In the United States of America, an extraordinary event occurred recently that attracted attention and made many nature lovers from all over the world happy.

A white bison was born in Bear River State Park, an extremely rare animal estimated to be present in one in ten million births, as reported by 'The Guardian'.

This calf is considered the most sacred living being on Earth for some tribes. Despite its low weight, the calf has shown astonishing health. 

The birth of this white bison is big news that has generated enormous interest and led to a significant increase in the number of visitors to the park, eager to admire this unique rarity up close.

Anyone who lives with one or more cats knows how pleasant and relaxing it can be to enjoy a cat's purr. However, those who think that a cat is always able to purr might discover some interesting curiosities.

The cat may not purr at all and this does not at all mean that it does not feel affection for the humans it lives with (it may show this in other ways).

So what are the cases when the cat does not purr? Let us try to understand more.

Parasites are a constant concern for anyone with pets. Fleas, ticks and mites can cause discomfort and health problems for our four-legged friends.

It is essential to take preventive measures to protect dogs and cats from these unwanted pests.

Here are five valuable tips to protect your pets and keep your home environment safe and comfortable.

If until a few years ago the monk seal was an endangered species, now sightings of this animal are becoming increasingly frequent. 

All this has convinced the WWF to publish a vademecum with the aim of disseminating correct behaviour in the event of a sighting, so as not to disturb the species and to inform researchers with all the elements that can make identification easier.

So what behaviour should be adopted in the event of a sighting and close encounter with these animals? Let's find out more.

The companionship of a dog is unique because it gives so much affection in a relatively short time compared to human life.

In fact, the average dog can accompany its owners for about ten years, but its life expectancy varies from breed to breed, but also according to various subjective factors.

A study conducted by the National Taiwan University and the Royal Veterinary College, published in the journal 'Scientific Reports', has revealed which dogs live the longest.

When temperatures rise in the summer heat, even cats can have some trouble coping.

Human friends, from this point of view, can take a few steps to help cats cope with the heat more easily. These are small gestures that, on the whole, can be of great help.

So what should you do if your cat suffers from the summer heat? Let us find out.

The giraffe is the tallest land animal and the largest existing ruminant.

Its main features lie in its neck and legs, which appear extremely elongated and excellently able to handle the pressure inside the blood vessels.

Apart from this, also characteristic of the giraffe are the horn-like ossicles that appear on its head, and the beautiful large black eyes with long eyelashes. The characteristic spotted coat changes according to subspecies.

The animal kingdom is full of wonders and oddities that characterise different species. 

Did you know, for example, that when a giraffe gives birth to a baby, it falls from a height of 2 metres without suffering any damage? Or did you know that some lions are able to reproduce up to 50 times a day?

No matter how much knowledge we have about animals, there is always something new to discover. Let's look together at some curiosities about animals that will probably surprise you.

New scientific research has been able to show how, just as human mothers do with their children, dolphin mothers also use 'baby-talk', a kind of language and tone of voice that they use when they need to communicate with their babies.

The study meticulously analysed sounds collected by researchers at the Woods Hole Oceanographic Institution (WHOI) and was published in 'Proceedings of the National Academy of Sciences' (PNAS). The original title of the article is 'Bottlenose dolphin mothers modify signature whistles in the presence of their own calves'.

The authors of the study therefore found several similarities in the behaviour of humans and dolphins, and they hope that these new findings will especially help to protect this delicate species from future threats. Furthermore, it is hoped that this study will serve as a source of inspiration for other similar research on the types of language and behaviour that mothers use with their pups.

Butterflies are distinguished by their extraordinary beauty and wonderful variety of colours, shapes and sizes. 

A true source of inspiration for nature lovers and photographers, these creatures are among the most incredible and stunning in the world.

In this article, we will take an in-depth look at the unique characteristics and habitats of some of the world's most beautiful butterflies, giving you the opportunity to get to know and appreciate their extraordinary beauty even more.

If we explore the animal world, we discover that there are many curiosities about the behaviour and habits of the Earth's most popular species. 

Giraffes are animals full of curiosities to discover. 

Did you know, for example, that they get very little sleep or that they cannot touch the ground with their mouths?

Let's find out some interesting facts about giraffes, the world's tallest animals that live exclusively on the African continent.

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.

The elephant is the largest mammal living on our planet today. Male specimens of the African elephant, for example, can exceed three meters in height and weigh over five tons.

Today you can find the two species of elephants-savannah and forest-living in Africa and the Asian elephant, which inhabits South Asia and Southeast Asia instead.

Elephants tend to live in groups consisting of related female specimens and their own cubs, with the older female being considered the matriarch.
