3. Blue Whale
Blue Whales are marine mammals. They are thought to be the largest that have ever lived. Some large blue whales are about 180 tonnes. Blue whales are endangered mammals. Before the 1900s, there were about 250,000 blue whales. They were found in oceans around the world. The largest population was in Antarctic waters. Overtime, these numbers have steadily gone down. In 2002, it was thought that there were between 5,000 and 10,000 blue whales left world wide. However, conservation efforts are having an effect. There are now between 10,000 and 25,000 blue whales.

4. Killer whales
The Killer whale is commonly referred to as the Osca and less commonly known as the Black fish. The Killer Whale is a toothed whale belonging to the oceanic dolphin family. Killer Wahles are found in all oceans from the frigid Artic and Antarctic regions to tropical seas. Killer Whales can be up to 6-8 metres long and weigh about 6 tonnes. World wide population estimates a minuim of 50,000 Killer whales. 25,000 in the Antartic, 8500 in the tropical Pacific, off the  cooler North East Pacific and off Norway.

5. Grey Whale
The Gray Whale is a balleen whale hat migrates between feeding and breeding ground yearly. It reaches a length of about 16 metres, weighs 36 tonnes and lives up to years. The common name of the whale comes from grey patches and with mottlings on its dark skin. Grey whales were once called Devil Fish because of their fighting behaviour when hunted. People presumed a population of 20,000-22,000 Gray whales. Humans and the Killer whale (Orca) are the only predators of the GTray whale.

6. Bow-head Whale
The Bow-head whale is a Baleen whale of the right whale family. A bow-head whale is a stocky dark-coloured whale without a dorsal fin. It can grow to 20 metres in length. This thick species can weigh tonnes, second only to the Blue whale. The Bow-head whale was an early whaling target. Its population was severely reduced before The population is estimated to be over 24,900 worldwide, down from an estimated 50,000 before whaling. The Bow-head is a slow swimmer and usually travels alone or in small herds of up to six.

7. Fin Whale
The fin whale is also called the fin-back whale, razorback, or common rorqual. The fin whale is a marine mammal belonging to the suborder of baleen whales. It is the second largest living animal after the blue whale. The fin whale can be a length to up to 27 metres long and can weigh as much as 70,000 kilograms. The fin whale can live up to years. Almost 750,000 fin whale we're taken from the Southern Hemisphere alone, between and less than 15,000 currently remain in that region. In fin whales were killed during the whaling season.

8. Humpback Whale
The humpback whale is a species of the baleen whale, on of the rorqual species. The humpback whale is a length from metres and weighs approximately 36,000 kilograms. Humpback whales can live up to years, but scientists discovered a humpback that was 211 years old. It was estimated that during the 20th century, at least 200,000 humpback whales were killed, reducing the global population by over 90%. By the beginning of the 21st century the population reduced to around 5,000 humpback whales.

9. Minke Whale
Minke whale is a name given to two species of marine mammal, belonging to a clade within the suborder of baleen whales. The Minke whale can live up to 6-8 years of age. The Minke whale can be a length up up 6.9 metres and can weigh up to  4-5 tonnes. The Minke whale is a black/grey colour. There are about 103,000 Minke whales in just the Northeastern Atlantic. In ,000 Minke whales were killed, and now there are only 670,000 left. In Minke whales were killed were killed in the Northern Atlantic.
