Dolphin (old Greek δελφίς – delphis, meaning “with the mater” or “fish with the mater”) is a water mammal related to whale, known for her intelligence and supposed sympathy and joy.
A dolphin group is called a flock.
The word “dolphin” has more meaning and can mean:
• Each member of the Delphinidae family (okean dolphins);
• Each member of the Delphinidae and Platanistodae family (okean and river dolphins);
• Each member of the Subgroup of Odocents (including denture whales);
• members of the Tursiops truncatus (spotted dolphin), the most prosaic and the most popular dolphin species
Orcs and some related species belong to the Delphinidae family. They can be counted among dolphins, although commonly referred to as whales.
There are about 40 types of dolphins in 17 genera. Their size varies from 1.2m and 40kg (Maui Dolphin), up to 9.5m and 10t (orcs). Maui dolphins are the smallest dolphin type, about 1.2 meters long and about 40 kg heavy. The largest species are orcs, or killer whales (yes, they are technical dolphins), and males of this species usually grow about 6-8 meters and are often more than 6 tons.
They can be found everywhere, usually in shallow seas of continental sheep. Dolphins are omnivores. They eat mostly fish and squid. The Delphinidae family is the largest in Cetaceae, and relatively young: dolphins appeared about 10 million years ago during the Miocene.
Dolphins have a long life span. The most famous species, Tursiops (Bottlenose), has an average life span of 40 years. Orcees are in the 80’s.
When they sleep, half of the dolphin’s brain is awake about 8 hours per day, the other resting and vice versa, because they do not breathe automatically (they do not have gills, and every 5 to 8 minutes breathe air). This state of affairs allows the dolphins to be aware of, to control the breathing and periodically drip into the surface to take the air. Dolphins use eyebrows and ecology (similar to sonar) to avoid obstacles and find prey.
Some scientific research suggests that dolphins teach their youngsters to use tools (eg, covering their spleen mites to protect them from sludge). Dolphins hold a kind of funeral ceremony for their dead.
The ancient Romans used dolphins in fishing. They were training them to push smaller fish to fishermen. When enough large groups of fish are gathered in one place, the dolphins would signal fishermen it’s time to throw their nets. Today, this practice can be seen in Santa Catarina (Brasil).
The only dolphins in the Amazon River swim upside down. Coats on their backs help them to ‘feel’ the bottom of the river to find food there. They better see what’s under them, because they have slightly bigger cheeks under their eyes, making them look down.
In addition to humans, dolphins are the only species of animals that develop a natural form of type 2 diabetes. They can be drugged. They have the ability to recognize, remember, and solve the problem. They are considered by one of the most intelligent creatures on the planet. May be happy, sad, even angry. There are a number of cases where they have become wicked, and revenge on people. When they are excited and happy, they play with other types, humans and dogs.
Dolphins consider pregnancy as a fascinating occurrence. Although they do not think any harm, they will gather themselves around the pregnant woman. Pregnant women are forbidden to swim with dolphins (though it seems they should be recommended), is that some women might be scared when all the dolphins come up against them – and sue the water park.
The fin flax at each dolphin is different, and is used for easier identification and identification. Dolphins are empathic moms. Numerous cases indicate that dolphins help each other in distress. They help older dolphins in the group. I can also make ‘rafts’ out of my body, and so bear the sick or hurt. They help people in trouble and whales bigger than them.
Dolphin males love their females. They collect sea grass to make something that resembles a bouquet of flowers which they take to their females. Initially, scientists thought they were playing until they noticed that males always made these ‘bouquets’ in front of the females.
Dolphins have their own names. By whistling they call each other ‘by name’ (each responds to a different whistle).
When they are captured, dolphins decide on suicide, which they do in many ways. The most common forms of dolphin suicide are refusing food or ‘jerking’ the head from the pool walls.
The Blue World Organization (Adopt a dolphin), Mali Lošinj-Croatia
By adopting the dolphins you support the Adriatic Project Dolphin, the longest scientific-research project in the region. Your generous support enables us to continue our research activities and the protection of good dolphins, as well as all other dolphins and whales in the Adriatic Sea, and to raise public awareness of them at local and national level. This is also support that also provides for the maintenance of the Dolphin Days and the continuous implementation of educational activities at the Lošinj Education Center on the Sea and the promotion of comprehensive protection of the Adriatic Sea and the general marine environment.
Activities of the Blue World Research and Protection Institute are conducted through three main programs – research, education and protection program. The research program is primarily aimed at monitoring large vertebrates in the Adriatic Sea – whales, sea turtles and cartilage fish, to contribute to their protection and conservation. Research results support educational content and activities aimed at engaging the general public. Our offices and field activities are positioned on the Adriatic islands as part of our contribution to the sustainable development of local communities. Most of the activities of the Blue World Institute take place in the northern and central Adriatic, on the islands of Lošinj, Murter and Vis. The Blue World Institute cooperates with many other institutions, non-governmental organizations and state bodies in the development of the Adriatic Sea policy.
Our headquarter is located in the Lošinj Education Center on the sea at the shore of Veli Lošinj. The office of the researcher is located in the premises of the Veli Lošinj Clinical Spa. The exploration vessel is anchored in the harbor near the education center. The research and volunteer house is located on the shore of Mali Lošinj. Research facilities on Vis and Murter do not have spaces open to the public, but only offices for the Institute of the Blue World Institute.
