They recognise their own reflection in a mirror they inspect themselves and look at parts of their bodies in the mirror that they can’t usually see, they also make movements and examine themselves for this movement. They will work together to take care of injured or sick pod mates.ĭolphins are one of only a few species that pass the ‘mirror test’.
They are creative and playful creatures, and seem to enjoy playing and seek the companionship of others. Dolphins have senses of empathy, altruism and attachment. They make plans together and cooperate with one another to hunt, protect themselves and bring up their young. They are fast learners, have advanced communication systems and develop complex social networks. And their offspring are totally dependent on their parents during childhood.ĭolphins have large and complex brains. They can assess situations and problem solve. They demonstrate complex emotions such as happiness, sadness and grief. Large brain animals like humans, chimpanzees, and dolphins have a number of things in common. Dolphins clearly demonstrate the ability to do all of these things and most scientists agree that dolphins are very intelligent creatures.ĭolphins have a large brain. Blue whales have the biggest hearts on the planet a football team could stand on a blue whale's tongue without falling off and they give birth to the biggest babies too.Īlthough it is hard for scientists to agree on how best to measure intelligence and it is difficult to compare intelligence from one species to another, broadly speaking, intelligence can be defined as the ability to learn and apply knowledge to understand new or challenging situations and the ability to think abstractly. With such gigantic proportions you’d expect some other record-breaking achievements and, again, the blue whale doesn’t disappoint. Even an average blue whale weighs 145 tonnes or as much as 25 adult African elephants. She weighed 190 tonnes (418,878 lb) which is equivalent to about 30 elephants or 2500 people. The heaviest blue whale was also a female hunted in the Southern Ocean, Antarctica, on 20 March 1947. The l ongest blue whale on record is a female measured at a South Georgia whaling station in the South Atlantic (1909) she was 33.58m (110ft 17in). Blue whales in the Southern Hemisphere are generally larger than those in the Northern Hemisphere and female blues are larger than males.
Blue whales and the other ocean giants live their whole lives in seawater, where their bodies are fully supported.īlue whales commonly reach 29m (95ft) in length, that’s roughly as long as a basketball court or three London red double-decker buses parked end to end. Blue whales are mind-bogglingly gigantic they are larger than any of the dinosaurs. The blue whale is not only the biggest whale living today the blue whale is the biggest creature ever to have lived on Earth.
