The World of Animals, Astonishing and Surprising

Dolphins, a complex language and great intelligence

Dolphins are one of the most intelligent creatures on the planet. They are endowed with a complex language and cognitive abilities that fascinate scientists. These marine mammals use a system of clicks and whistles to communicate with each other. Each dolphin has its own "signature whistle," a kind of unique name that allows it to be identified by other members of its group. Additionally, they are able to recognize their reflection in a mirror, a sign of self-recognition, which is a form of higher intelligence.

The great white shark and its keen senses

The great white shark is a formidable predator and its senses are extremely developed. Its ability to detect a drop of blood in the water from more than 4 kilometers away is an astonishing fact. The great white shark has an additional sensory organ, the ampullae of Lorenzini, which allows it to detect electromagnetic fields emitted by animals, even if they are motionless. It is this sixth sense that allows it to hunt with formidable precision, as it can detect fish hidden in the sand.

Snails and spiders, survival records

Snails and spiders can survive in extreme conditions. Snails can remain in a state of hibernation for several years if they cannot find a suitable environment. This survival ability allows them to wait for more favorable conditions. Spiders, on the other hand, can survive without food for many months, or even years, thanks to their slow metabolism. For example, a black widow can live a year without eating, which is an incredible feat.

The dung beetle, an outstanding navigator

The dung beetle, a small insect that rolls balls of dung, is an exceptional navigator. Researchers have discovered that it is the only animal in the world capable of orienting itself by using the polarized light of the Milky Way to navigate. This skill is crucial to allow it to quickly move away from the dung, which prevents it from having its precious ball stolen by other insects. It is a fact that shows how incredibly adapted animals can be to their environment.
