Dolphin is aquatic mammals. There are 36 dolphin species, found in every ocean. Dolphins live in complex social groups and have evolved to have highly-developed brains. Dolphins are extraordinarily intelligent animals who also display culture, something which was long-believed to be unique to humans. Dolphins are altruistic animals. Dolphins play an important role in keeping their environment in balance. Without dolphins, the animals they prey on would increase in number, and their predators wouldn’t have as much to eat. Dolphins have a reputation for being friendly, but they are wild animals who should be treated with caution and respect. Dolphins are carnivores, mostly eating fish and squid.
TYPES OF DOLPHINS:
There are different types of dolphins. Some of them are,
- Common bottlenose dolphin:
The common bottlenose dolphin or Atlantic bottlenose dolphin is the most well-known species of the family Delphinidae. Common bottlenose dolphins are grey. Common bottlenose dolphins and other dolphins are thought to be some of the smartest animals.
- Striped dolphin:
Striped dolphins are among the most abundant and widespread dolphins in the world. Striped dolphins are relatively small, streamlined, and colorful. Striped dolphins are known for their distinct and striking coloration pattern, which includes bold, thin stripes that extend from the eye to the flipper and another set of stripes down the side of the body to the anal region. Striped dolphins are extremely active and fast. Striped dolphins are widely distributed throughout the world’s temperate and tropical oceans.
- Dusky dolphin:
The dusky dolphin is a dolphin found in coastal waters in the Southern Hemisphere. The dusky dolphin has a long, light-grey patch on its foreside leading to a short, dark-grey beak. The throat and belly are white, and the beak and lower jaw are dark greys. Two blazes of white color run back on the body from the dorsal fin to the tail.
- White-beaked dolphin:
White-beaked dolphins are found throughout the cold waters of the North Atlantic Ocean. They are active swimmers. The white-beaked has a short beak. The upper body and flanks are dark grey with light grey patches, including a ‘saddle’ behind the dorsal fin, while the underside is light grey to almost white.
- Spinner dolphin:
The spinner dolphin is a small dolphin found in off-shore tropical waters around the world. Spinner dolphins earned their name because of their ability to spin multiple times in one jump. Scientists believe they spin for several reasons, including communication, removing parasites, and simply for the fun of it.
- Irrawaddy dolphin:
The Irrawaddy dolphin’s color is grey to dark slate blue, paler underneath, without a distinctive pattern. It has a large melon and a blunt, rounded head, and the beak is indistinct. Irrawaddy dolphin Communication is carried out with clicks, creaks, and buzzes at a dominant frequency of about 60 kilohertz, which is thought to be used for echolocation.
- Long-beaked common dolphin:
The long-beaked common dolphin is a species of common dolphin. Long-beaked common dolphins generally prefer shallow, tropical, subtropical, and warmer temperate waters within 15 nautical miles of the coast and on the continental shelf. The long-beaked common dolphin is generally larger with a longer beak than the short-beaked common dolphin and has a longer rostrum. They are also highly vocal.
- Rough-toothed dolphin:
The Rough-toothed Dolphin is a fairly large dolphin that can be found in deep warm, tropical, and subtropical water from the western Pacific to the Mediterranean. Their flanks are light grey and the back and dorsal fin a much darker grey. Rough-toothed dolphins have sharp, serrated teeth.
