Specific fish species, such as certain mudskippers, possess morphological adaptations that enable them to climb trees and other vertical terrestrial surfaces.

Evidence for · 2
The significance of pelvic fin flexibility for tree climbing fish.
2016 · cited by 24
Demonstrates that the mudskipper species Periophthalmus variabilis climbs trees and rocks.

The analysis

Papers [0] and [2] explicitly document mudskippers (specifically Periophthalmus variabilis) climbing trees and rocks, establishing that certain fish species can indeed climb trees. The remaining papers discuss general amphibious locomotion, terrestrial movement, or fish biology without contesting this specific capability.

More for · 1
The water-hopping kinematics of the tree-climbing fish, Periophthalmus variabilis.
2020 · cited by 10
Observes that Periophthalmus variabilis launches and lands on inclined-to-vertical surfaces such as rocks and trees.
