Black Sea bottle-nosed dolphin (Tursiops truncatus ponticus)

Black Sea bottle-nosed dolphin. Baltic Sea mammals

The dolphin belongs to the class of mammals, the suborder of toothed whales. The species representing this suborder can mostly be found in the Black Sea. The dolphin’s length can exceed 2 m and it can reach a weight of 200 kg or more. Despite their weight and length, dolphins can swim at a speed of 45 km/h. The secret of their speed lies in their streamlined shape and the unique structure of their skin. The dolphin’s weapon is its pointed and very hard jaw, the rostrum. With the help of the rostrum dolphins defend themselves from sharks. The blow of the rostrum is so strong that it can crack the hard shell of a turtle. Dolphins have 88 sharp, cone-shaped teeth. The teeth are necessary not only for holding the fish until swallowing, but also for males fighting it out during the mating season. Dolphins breathe in such a way that air enters the lungs through a special opening on the top of their heads. They can stay underwater without breathing for 10 minutes. Dolphins are able to orientate themselves and get to know their environment by using their perfect eyesight, hearing and touch. Dolphins use their sense of hearing in combination with a very sophisticated ability known as echolocation. Emitting sounds at a frequency of up to 200 kHz, which reflect from an obstacle and come back as an echo, dolphins find out the shape, size, and distance to the object. This also permits dolphins to hunt their favourable prey. The dolphins have been living in the Dolphinarium at the Lithuanian Sea Museum since 1994. Being smart animals, dolphins take part in outstanding dolphin shows and help to bring joy to the lives of children with special needs. In 2002, the Lithuanian Sea Museum started a unique dolphin-children interaction project, Dolphin-Assisted Therapy.
