Beluga whales and dolphins are cetaceans in the animal, is a different species of two whales. Whales are mammals that live in the sea, and they are more intelligent than other marine animals around them. Beluga whales and dolphins are relatively intelligent whales, their IQ is relatively high. Belugas are more intelligent than dolphins. In some studies, researchers have found that dolphins have IQs similar to those of people aged 6-7, while belugas have lower IQs, similar to those of people aged around 3.
In aquariums, we can often see dolphins completing various complex performances, and they will actively interact with people, which shows their intelligence. Dolphins living in the ocean are also more intelligent, for example, they will use some skills when hunting. For example, when they encounter people who accidentally fall into the water, they may take the initiative to rescue them and push them to the shore.
Beluga whales and dolphins are very fast swimming animals. Adult dolphins can swim about 50 kilometers per hour, sometimes chasing ships, sometimes even faster than torpedoes. But dolphins are slower than belugas. Adult belugas can reach speeds of 50-60 kilometers per hour, sometimes slightly faster than dolphins, and are well-deserved "swimmers". But juvenile belugas don't swim as fast, typically at 20 to 30 kilometers per hour. As they grow up, they get faster and faster.
