There’s more to a jellyfish than meets the eye

Jellyfish are among the oldest creatures on the planet, but also subject to less research than most animals and science is only now catching up.

They have survived five mass extinctions and live in every ocean.

This video from the PBS Deep Look series investigates these ultimate survivors.
