How Fast Can The Fastest Whale Swim?

Whales are known for their incredible speed and agility in the water, with some species capable of reaching incredible speeds. Among the fastest of all whale species is the common dolphin (delphinus delphis), which can swim at speeds of up to 60 km/h (37 mph).

Dolphin’s Physiology

The common dolphin’s speed is attributed to its streamlined body shape and powerful dorsal fin, which helps to propel it through the water. Additionally, the common dolphin’s muscles are highly developed, allowing it to generate large amounts of power and maintain its high speeds for long periods of time.

The common dolphin’s body is also designed for maximum hydrodynamic efficiency. Its dorsal fin, tail flukes and flippers are all shaped to reduce drag and increase thrust. Its body is also covered in a thick layer of blubber, which helps to insulate it from the cold water and also provides buoyancy to help it swim faster.

Dolphin’s hunting technique

Common dolphins often hunt in groups, using a technique known as herding to chase and capture their prey. This typically involves swimming at high speeds in a tight formation, chasing and corralling fish or squid into a smaller area where they can be more easily captured. These hunting strategies require a high degree of coordination and maneuverability, which is facilitated by the common dolphin’s high speeds and agility.

In addition, common dolphins are known to use a variety of vocalizations and other forms of communication to coordinate their hunting efforts, including echolocation. This allows them to locate and track their prey even in low visibility conditions.


The common dolphin is widely considered to be one of the fastest species of whale, capable of reaching speeds of up to 60 km/h (37 mph). This impressive speed is a result of its streamlined body shape, powerful dorsal fin, and highly developed muscles, as well as its specialized hunting techniques and use of vocalizations and echolocation.
