Mammals (Mammalia)[edit]

1Giant Ai (Three-toed sloth) 3 mph (4.8 km/h)[1]The three-toed sloth is the slowest mammal on Earth, due to its lack of muscle tissue.It is so sedentary that algae grows on its furry coat. All sloths are built for life in the treetops. Three-toed sloths also have an advantage that few other mammals possess: They have extra neck vertebrae that allows them to turn their heads some 270 degrees.


Birds (Aves)[edit]

1American Woodcock 5 mph (8.0 km/h)[3]The American Woodcock has been timed flying at 5 mph without stalling during courtship displays.[4]

Reptiles (Reptilia)[edit]

1Giant Galapagos Tortoise 1 mph (1.6 km/h)[5]The Galapagos Tortoise can be as slow as 0.23 miles per hour on land. In the water, Galapagos Tortoises can move much faster than this.


1Seahorse 5 ft (150 cm)[6]The Dwarf Syngnathidas swims at about 0.01 mph, making it the slowest fish in the world. They are found in shallow tropical and temperate waters throughout the world. Unlike most other fish, they are monogamous and mate for life. Rarer still, they are among the only animal species on Earth in which the male bears the unborn young.



Mollusks (Mollusca)[edit]

1Banana slug 0.000023 m/s (7.5×10−5 ft/s)[8]The Banana Slug is said to be the slowest mollusk in the world, as its average speed is only approximately 0.000023 m/s.[9]


1Coral 0 m/s (0 ft/s)The coral is one of the only animals that do not move.
