Killer Dolphins Research Paper

Common bottlenose dolphins and killer whales are the most well-known types of the dolphin on Earth. Both of them are warm-blooded marine mammals belonging to the Delphinidae family. The scientific name of the common bottlenose dolphin is Tursiops truncatus, which means “dolphinlike”, and the killer whale is Orcinus orca, which means “of the kingdom of the dead”. This name is likely a reference to killer whales’ outstanding hunting skill. In Latin, orca means "large-bellied pot or jar". Both animals have several similarities and differences. They differ in their appearance, diet, and habitat, while feeding habits, behaviour, and breeding habits are very similar.

First of all, common bottlenose dolphins and killer whales differ in their appearance.

Common bottlenose dolphins feed on a variety of fishes, squids, and other crustaceans such as shrimps. On the other hand, killer whales feed on fishes, squids, and marine mammals such as birds and seals. They even attack polar bears and other whales. +eg

Lastly, they differ in their habitats. While Common bottlenose dolphins inhabit in the temperate, subtropical and tropical oceans worldwide, killer whales inhabit all oceans of the world.

In spite of these differences, common bottlenose dolphins and killer whales also have similarities. Firstly, they resemble each other in their behaviour. Both of them are highly social animals that live together in groups called pods. Pod sizes vary, but typically consist of a pair to 30 dolphins, although some pods combine to from a pod of 100 or more.

Also they are similar in their feeding habits. When they are hunting, they usually working together as a group. Also they use echolocation, it uses to locate prey and communicate each

They generally calve a single offspring and birth interval is averagely around three years. The period of nursing of the calf is about from 18 months to 2 years. But after nursing period, the calf generally stays with their mother until it is between 2 and 8 years
