Scientists stunned as African lake fly larvae defy deep-sea survival limits

Chaoborus edulis larvae in Lake Malawi survive deep-water pressure that would implode other insects.

The larvae perform a daily vertical migration of over 200 meters using specialized air sacs for buoyancy control.

A pH-powered mechanism in the air sac walls allows the larvae to precisely manage their depth.

The discovery by University of British Columbia researchers Dr. Philip Matthews and Dr. Evan McKenzie challenges assumptions about insect survival in deep water.

The finding offers insights into insect evolution and potential applications in material science.
