What is the highest speeds dolphins have been known to attain?

Dolphins have shown impressive speed during short burst, with certain species capable of reaching remarkable velocities. While exact numbers can vary based on the species and individual dolphins, some have been recorded to attain the following speeds:

1. Pacific White-Sided Dolphin (Lagenorhynchus obliquidens): In 2013, marine biologists recorded a Pacific White-sided Dolphin off the coast of California reaching an astonishing speed of 29 mph (47 kph).

2. Risso's Dolphin (Grampus griseus): In a study off the coast of Spain, Risso's Dolphins were found to swim at speeds of up to 25 mph (40 kph).

3. Common Bottlenose Dolphin (Tursiops truncatus): Common Bottlenose Dolphins are known for their speed and agility. They have been recorded swimming at speeds up to 24 mph (39 kph).

4. Atlantic Spotted Dolphin (Stenella frontalis): These playful dolphins have been observed swimming at speeds of around 22 mph (35 kph).

5. Atlantic White-Sided Dolphin (Lagenorhynchus acutus): Atlantic White-sided Dolphins have been clocked at speeds up 21 mph (34 kph).

It's worth noting that these speeds are typically attained in short, explosive bursts, and dolphins cannot maintain these speeds for extended periods. Moreover, not all dolphins are created equal in terms of speed, and specific factors like body size, age, and motivation can influence a dolphin's maximum swimming speed.
