Scientists have only discovered one other animal that can control its
buoyancy in the water using swim bladders, and it’s not fish. The larvae of
the phantom midge, a species of lake fly, belonging to the genus Chaoborus,
develop in water before emerging as adult flies. Due to their transparency,
scientists have known since 1911 that glass worms have two sets of
gas-filled sacs on their extremities.
