By speed · Order from slowest to fastest.

  1. A swimming seahorse 1.5 m/h

    The dwarf seahorse is the slowest fish on record, fluttering a tiny fin dozens of times a second to barely move.

  2. A three-toed sloth 240 m/h

    Sloths move so slowly that algae grows in their fur, giving them a greenish camouflage in the canopy.

  3. A mosquito in flight 2.4 km/h

    Only female mosquitoes bite; they need a blood meal to develop their eggs, while males sip flower nectar.

  4. A swarming desert locust 14.5 km/h

    A single locust swarm can contain billions of insects and devour as much food in a day as tens of thousands of people.

  5. A running roadrunner 32 km/h

    Real roadrunners prefer sprinting to flying and can kill rattlesnakes, far from the cartoon's gentle dodging.

  6. Concorde at cruising speed 2.2K km/h

    Concorde flew so fast that the friction heated its frame, stretching the whole plane several inches in flight.
