What is the fastest animal in water?

Speed is fundamental for the survival of animals on land and in water. Water animals have adapted to outrank the fastest race cars with swiftness that allows them to catch prey or evade predators. Their body features and specially adapted features, such as oil glands in Swordfish, only function to enhance acceleration.

Knowledge of these creatures' special abilities helps increase animal awareness for their conservation and protection. Here is a full list of the fastest animals in the water.

1. Black Marlin — 132 km/h (82 mph)

• Habitat: Indian and Pacific Oceans
• Size: Over 10 feet long (3 metres)
• Diet: Small fish and squid

The black marlin stands out as the fastest fish in the ocean. In October 2014, a fishing exercise discovered that the Black Marlin's top speeds rivalled a Formula 1 racing car. Its aerodynamic body and crescent-shaped tail work together to reach over 80 mph.

Its muscle composition, fast-twitch fibres, elongated tail muscles, and rigid, non-retractable pectoral fins allow it to achieve lightning speeds. With speed on its side, the Black Marlin is a formidable predator and a prize catch for fishermen.

2. Sailfish — 110 km/h (68 mph)

• Habitat: Atlantic and Pacific Oceans
• Size: Up to 11 feet long (3.4 metres)
• Diet: Smaller fish and squid

The Sailfish is known for its unique sail-like dorsal fin that stretches across the entire length of its back. It also has a slender body with long pelvic fins. Speed allows the Sailfish to catch prey and evade predators.

Its incredible speed and size make it a challenging but prized catch for fishermen. The Sailfish showcases the remarkable adaptations fish have developed for survival in their aquatic environments.

3. Swordfish — 97 km/h (60 mph)

• Habitat: Atlantic, Pacific, and Indian Oceans
• Size: Up to 10 feet long (3 metres)
• Diet: Fish, tuna, squid, and crustaceans

The Swordfish has a flat, pointed, and elongated bill used to slash through prey. This powerful predator has a streamlined shape, influencing its speed and agility. Its physical attributes also help it swim over long distances.

With its remarkable adaptations, the Swordfish is an essential part of marine ecosystems and showcases the evolutionary advantages that speed can provide.

4. Wahoo — 97 kph (60 mph)

• Habitat: Warm seas
• Size: Up to 8 feet long (2.4 metres)
• Diet: Fish and squid

The Wahoo is known for its impressive speed, which it uses for agile ambush tactics. This warm-seas predator has a high proportion of fast-twitch muscle fibres, allowing it to accelerate rapidly to escape predators.

With its sleek body and quick movements, the Wahoo exemplifies the adaptations that enable fish to thrive in competitive environments.

5. Yellowfin Tuna — 80 km/h (50 mph)

• Habitat: Indian, Pacific, and Atlantic Oceans
• Size: Up to 7 feet long (2.1 metres)
• Diet: Fish, squid, and crustaceans

Yellowfin Tuna is a remarkable swimmer, easily identifiable by its striking yellow dorsal and torpedo-shaped body. This fish can travel at high speeds and long distances, aided by its unique muscle structure and sturdy fins.

Its adaptations not only make it a formidable predator but also highlight the importance of speed in the marine ecosystem.

6. Shortfin Mako Shark — 72 km/h (45 mph)

• Habitat: Tropical and temperate oceans worldwide
• Size: Up to 12 feet long (3.7 metres)
• Diet: Tuna and other sharks

The Shortfin Mako Shark is one of the ocean's legendary speed demons. Known as the fastest shark in the world, its conical snout and crescent-shaped tail produce maximum thrust with minimum drag.

This shark's incredible speed makes it a prized catch for fishermen and a critical player in marine food webs.

7. Bluefin Tuna
