6. Byrde’s whale

Byrde’s whales are impressive giants measuring up to a maximum of 14m and weighing between 12 and 25 tons and are easily distinguished by their curved dorsal fin. These animals, according to Simon’s are rorqual whales. This means they can open their mouths very wide due to the grooves along their throat. This allows the animal to take in massive amounts of water when feeding. These whales are dark grey along their upper body with a lighter underbelly, which becomes white in their mid section.

7. Southern right whale

Southern right whales have and interesting ‘filter’ built into their mouths. These whales have between 200-270 fine ‘plates’ in their upper jaw that hang downwards, filtering the animal’s food. This feature is what makes Southern rights baleen whales. Whale hunters called these animals and their counterparts in the northern hemisphere the ‘right’ whale, as it is rich in oil and not a very fast swimmer. Measuring between 15-17m, these giants can weigh between 20 and 40 tons.

8. Humpback whale

Humpback whales are identified by their long white flippers, which can measure to nearly one third of the entire length of its body. The humpback whale is roundish and short, in whale standards. These animals are known as the ocean’s acrobats for their playful activity. They aren’t afraid to breach – jump out of the water completely – or lobtail – slap their tail on the water.  Another of the humpback’s tricks is to ‘spy hop’ which is when the whale sticks its head out of the water. These animals are also rorqual whales. They measure between 13,1m and 13,7m and weigh between 30 to 50 tons.
