Catfish Caught on Video Climbing up Cave Wall

Scientists in Ecuador have captured incredible footage of catfish climbing up a waterfall to lick food from the roof of a cave.

This is the first time this behavior has been caught on film. The scientists were cataloging the various animals found in the cave when they noticed a species of armored Amazonian catfish climbing up a steep flow-stone waterfall. Luckily, the team had a camera on them and captured the action.
