Scartelaos histophorus (Valenciennes, 1837)

Taxonomic Classification

Scartelaos histophorus, commonly known as the walking goby, is a species of fish in the family Oxudercidae.

Terrestrial Locomotion

This species is notable for its unique ability to "walk" on land, using its pectoral fins to propel itself forward.

Habitat and Distribution

Walking gobies are typically found in shallow coastal waters, such as mudflats, estuaries, and mangrove areas, in the Indo-Pacific region.

Locomotion Function

The ability of Scartelaos histophorus to move on land helps it migrate between different tidal pools and avoid predators in its aquatic environment.

Environmental Adaptation

This behavior is part of a broader adaptation to fluctuating environments, where the fish may need to move between water bodies when the tide goes out.

Air Breathing Trait

Walking gobies can also breathe air, which further aids their survival in low-oxygen environments.
