3 WHICH IS THE BIGGEST WHALE? The blue whale is the largest animal ever to have lived on Earth; it is larger than any of the dinosaurs. The biggest recorded blue whale was a female in the Antarctic Ocean that was 30.5 m long (more than 3.5 times the length of a double-decker bus and as long as a Boeing 737 plane) with an estimated weight of 144 tonnes (almost the same as 2,000 men). The tongue alone of a blue whale can weigh as much as an elephant and an entire football team could stand on it!

5 WHICH WHALE IS THE DEEPEST DIVER? A Cuvier's beaked whale has been recorded to dive to a depth of 3km for over 2 hours. Sperm whales are also champion divers. Adults can stay underwater for almost two hours and dive to depths of 2,000 metres or more. They eat squid, which can live very deep in the ocean, so sperm whales have to dive down into the deepest parts of the sea to catch them

6 WHICH WHALE HAS THE THICKEST BLUBBER AND LONGEST BALEEN? The bowhead whale, which lives exclusively in the Arctic, has the thickest blubber of all whales. It can reach a whopping 70cm in thickness. These whales also have the longest baleen – the comb-like structures hanging down from their upper jaws used as a sieve to filter food from the sea-water. These baleen plates can reach up to 5 metres in length.

8 WHICH WHALE HAS THE BIGGEST BRAIN? The sperm whales huge head, which is up to a third of its overall body length, houses the heaviest brain in the animal kingdom - up to 9kg. The head also consists of a cavity large enough to park a car inside that contains a yellowish wax called spermaceti that was much sought after by whalers.
