Mudfish Literally Can Climb Trees
Have you heard the maxim that everybody is an Einstein, but if you judge a fish by its ability to climb a tree, it will always believe it is stupid? Who said that had never encountered the mudfish, a fish that could climb trees? And not underwater trees, but trees above the surface.
Mudfish have little sacs around their gills that allow them to hold their breath when they are above water. And surprisingly, they do spend quite a bit of their time above water! They usually live among mangrove trees and climb the trees to avoid high tide.
