Hatchetfish

About

How hatchetfish lives

Hatchetfish are small freshwater surface fish with deep bodies and upward-facing mouths. Some hatchetfish leap from water using strong pectoral muscles. River species are shaped by changing water levels, flowing currents, and narrow migration paths.

Conservation

Status and habitat pressure

Stable populations still depend on habitat quality, food availability, and low human pressure. Protecting hatchetfish also depends on keeping rivers, wetland habitats healthy and connected.

Common species still depend on habitat quality, clean water, food webs, and low disturbance.
