The fastest swimming animal is the common dolphin, also known as the short-beaked common dolphin (Delphinus delphis). It can reach speeds of up to 60 km/h (37 mph).
Dolphins are known for their agility and playful behavior in the water. Their streamlined bodies and powerful tails allow them to propel themselves at impressive speeds. The common dolphin’s speed is not just for show; it helps them evade predators and catch fast-moving prey like fish and squid.
In addition to the common dolphin, other fast swimmers include the sailfish and the orca, or killer whale. Sailfish are often recognized as the fastest fish, capable of swimming at speeds around 68 mph (110 km/h) during short bursts. However, when considering overall swimming ability and sustained speed, the common dolphin takes the top spot.
