Mola mola survives crushing depths without a swim bladder

The mola mola, one of the ocean's heaviest bony fish, has no swim bladder. Instead it relies on a thick, gelatinous layer under its skin to cope with pressure changes as it dives deep to hunt jellyfish. The fish's unusual biology was highlighted in an episode of "The Nature of Things," hosted by Sarika Cullis-Suzuki and Anthony Morgan.

Why now: The striking adaptation of the mola mola is being shared as a surprising ocean fact from a recent science show episode.
