Dolphins are highly intelligent marine mammals, known for their gentle nature, sociability, and interactions with humans.

There are various species of dolphins around the world, each differing significantly in size, behavior, and habitat.

This article introduces some of the most famous dolphin species.

1. Bottlenose Dolphin

The bottlenose dolphin is one of the most well-known dolphin species, often featured in marine park shows and frequently appearing in TV programs and movies. Bottlenose dolphins typically range from 2.5 to 4 meters in length and weigh about 150 kilograms. They have the characteristic short snout and curved dorsal fin.

Bottlenose dolphins live in warm seas, typically in coastal and shallow waters. They are highly intelligent, capable of using tools, engaging in complex social interactions, and even being trained for performances with humans. Bottlenose dolphins are also widely used in scientific research to study animal cognition and behavioral patterns.

2. Commerson's Dolphin

Commerson's dolphin is a smaller species, measuring about 1.5 to 1.7 meters in length, native to the Antarctic waters of South America, particularly around Argentina and the Falkland Islands.

Their distinctive black and white skin, with a black back and a white belly, gives them the appearance of wearing a "costume." Commerson's dolphins are lively and often leap out of the water, making them well-suited to navigating the rough seas.

3. Long-beaked Common Dolphin

The long-beaked common dolphin is a species found extensively in tropical and subtropical seas, particularly along the coasts of the Indian and Pacific Oceans. They have a medium-sized body, typically ranging from 2 to 2.5 meters in length and weighing about 80 kilograms.

The long, pointed snout is one of their most distinctive features. Long-beaked common dolphins live in groups and are highly social, often engaging in complex cooperative hunting behaviors within their pods. They primarily feed on fish and squid and are skilled at catching fast-moving prey.

4. Rough-toothed Dolphin

The rough-toothed dolphin is a rarer species, known for its long, pointed snout and unique rough teeth. They are typically 2 to 2.7 meters in length and weigh about 150 kilograms.

Rough-toothed dolphins are found mainly in tropical and subtropical waters, particularly in the Indian and Pacific Oceans. They often inhabit deeper sea areas and exhibit high agility while hunting.

5. Yangtze River Dolphin

Compared to marine dolphins, the Yangtze River dolphin is smaller, usually around 2.5 meters in length and weighing about 150 kilograms. The Yangtze River dolphin has grayish-white skin with a distinctive wide mouth on its head.

Dolphins are not only the "stars" of the oceans, but their diversity, intelligence, and behavioral patterns also captivate scientists and nature enthusiasts alike. The different species of dolphins each have unique characteristics in terms of habitat, behavior, and appearance, and they play a crucial role in the marine ecosystem.

However, many dolphin species are facing survival pressures due to environmental changes and human activities. Protecting these fascinating creatures has become a shared responsibility worldwide.
