Some information about Dolphins

There are about 36 species of dolphins divided into 16 genera. The smallest dolphin is the Haviside dolphin, with a length of 1.2 meters and a weight of 40 kilograms. The largest dolphin is the black and white killer whale, with males growing up to 9.8 meters in length and weighing 5.5 tons.

Dolphins mainly live in the shallower areas of the sea. They mainly eat fish and squid. There are considerable differences between the various species: for example, orcas catch much larger prey (including marine predators) than the common dolphin, which mainly lives on fish.


Like other whales, dolphins are known to be highly intelligent and social animals. They have relatively large brains, for which there are other explanations than high intelligence: dolphins do not have REM sleep and animals without REM sleep often have relatively large brains.

In 2001, a dolphin passed the so-called mirror test, in which an animal is placed in front of a mirror to determine whether it recognizes its reflection as itself. In the same year, researchers showed that dolphins understand the pointing of an object by a human.

Bottlenose dolphins are known to use sponges as tools (probably to protect the nose). In 2005 researchers argued that although this use occurs within one genetically related group, it cannot be genetically determined alone, thus demonstrating some form of culture.

Social interaction

Partly because of their intelligence, dolphins are social animals, living in groups of up to dozens of individual animals. In places where there is a large amount of food, groups can temporarily merge to form a super group, such groups can sometimes consist of more than 1000 dolphins. It is thought that a combination of curiosity and the playful nature of the dolphin ensures that they have frequent contact with other animal species, including humans. Dolphins are frequently observed to swim with boats. Their propensity for companionship is also manifested in the groups in which this animal lives. Individual animals communicate by making a variety of sounds, such as clicking and whistle-like sounds.

The group composition is not fixed; exchanges with other groups is common. Despite this, dolphins can build strong social bonds; they will stay with injured or sick individuals, even assisting with breathing by bringing them to the surface when needed. This altruism is also not limited to their own kind. The New Zealand dolphin Moko was observed escorting a female pygmy sperm whale and her calf out of shallow water after being stranded several times. Dolphins have also protected swimmers from sharks by swimming in circles to scare the swimmers or the sharks away.
