It is said that they can communicate vocally with each other and have their accents unique to the ‘pod’ they are from. The avarage life expectancy of a wild killer whale is as long as 90 years for females and it will go upto 60 years for males, however for captive killer whales are at best 30 years.

2. Sperm Whale (Physeter macrocephalus)

Sperm Whale is one of the strongest sea animals that can be seen in all oceans of the world. The population of sperm whales can be divided into groups that inhabit the north and south hemispheres. Sperm whales are one of the fishes with big foreheads that can grow between 49 to 50 feet in length and weigh between 35 and 45 tons. These animals with big noses are named because of the organ located in their heads known as spermaceti. Sperm whales have between 18 to 30 conical teeth in their tiny lower jaw and are hence listed as one of the fishes with the biggest teeth in the world. The avarage lifespan of sperm whales is between 50 to 70 years in the wild.

3. Great White Shark (Carcharodon carcharias)

Great White Shark is one of the different types of sharks in the world, however, they are one of the most popular 400 known shark species.

The specific coloration gives them excellent camouflage that prevents prey from seeing the shark. They have specific electro-receptors that help them to detect the electric field of all animals in the water.  The avarage lifespan of a great white shark is upto 60 years in the wild.

5. Blue Whale (Balaenoptera musculus)

Blue whale is the largest animal on the planet and can be found in all oceans in the world. It is believed that they have existed on the planet for 54 million years, however, the population has decreased drastically in the first half of the 20th century because of ocean pollution, increased sea traffic, climate changes, and oil spills. They can read upto 100 feet in length and 150 tons in weight. It is also one of the loudest animals on the planet and thier song can be heard miles away because their call has 190 decibels (peak of the rock music is 150 decibels). The avarage lifespan of blue whales is between 80 to 90 years in the wild.

6. Giant Squid (Architeuthis dux)

The giant squid is the largest of all squid species and the largest invertebrate on the planet Earth. As of now, the species has been discovered in the Northern part of the Atlantic Ocean, the Gulf of Mexico, the Northern part of the Pacific Ocean, the Sea of Japan, the Bering Sea, Hawaii, California, and in the southern oceans, however, it is believed that it is seen in all oceans of the world. The primary diet consists of other squids, fish, and shrimp. There are instances in which giant squid can attack and eat small whales.
