Mola mola survives deep dives without a swim bladder

The mola mola, one of the heaviest bony fish in the ocean, manages without a swim bladder. Instead, its thick, gelatinous hypodermis provides neutral buoyancy, allowing it to withstand crushing pressure changes as it dives deep to hunt jellyfish. The fish's unusual anatomy is featured in the Canadian science series 'The Nature of Things,' where hosts Sarika Cullis-Suzuki and Anthony Morgan examine how the species thrives in the open ocean.

Why now: The counterintuitive biology of a giant fish surviving deep-sea pressure without a swim bladder is fascinating viewers of the science series.
