Melon-Headed Whale - Despite their name, these “whales” are dolphins. They are also known as mask and are rather gray in color and have a dark grey face. They are called melon-headed since their head is round-shaped. But their head is not round as that of pygmy killer whales. It swims fast, making short low dives off the ocean surface, splashing plenty of water.
Killer Whale – Another dolphin with a “whale” name, they are the most powerful dolphin because of their size as well as their strength. They capable of taking down seals easily which is important because of the significant amount of food which they can eat every day.

They are the most social types of dolphins. Moreover, they are susceptible to pollution in their environment.
White-Beaked Dolphin – They are plump looking and can grow up to 3 meters. They are black or gray in color. Contrary to their name, they have gray-dark gray beaks, but a white abdomen. They are rather acrobatic and appear to have an exceptional ‘rooster tail splash’ when swimming quickly.

Dusky Dolphin – They reside in cooler water bodies as compared to other types of dolphins. They may also be found down the coastal regions.
Risso’s dolphin: They have square shaded head. Their upper jaw doesn’t have any teeth; however, their bottom jaw has a number of peg-like teeth.
Bottlenose Dolphin – They are very popular and are the most loved types of dolphins. They always appear to be smiling making them very attractive as they have a curved-shaped face which turns upward. They can grow up to 14 feet long and weigh around 1,100 pounds.
Hector’s Dolphin – They are very rare type of dolphins. They are also the smallest marine dolphins. Their body is torpedo-shaped and they have a very stocky short body.

There are only four types of dolphins that can thrive in freshwater rivers, which include the first four types. The last type, La plata dolphin, reside in salt-water estuaries. River dolphins have very large beaks, which might form 1/5 of the whole body length, as compared to oceanic dolphins. They can be found in range of colors, such as black, pink, yellow, white, gray or brown. They also have exceptionally well-developed brains as well as short, wide flippers. In addition, they don’t require vision since they reside in muddy water.
That should cover all of the dolphins out there. If you want to discuss dolphins, or remind me of one I’ve left off the list, feel free to leave a comment below.
