walking fish
Limbed aquatic creature
A walking fish is any fish that can move across land using modified fins or other adaptations.
Several species qualify—mudskippers prop themselves on pectoral fins, snakeheads wriggle overland, and lungfish can survive droughts in mud.
The term is descriptive rather than taxonomic, grouping unrelated species by shared behavior: The walking fish crossed the road to reach another pond.
