Jellyfish don’t have a heart, or blood, or even a brain. They’ve survived five mass extinctions. And you can find them in every ocean, from pole to pole. What’s their secret? Keeping it simple, but with a few dangerous tricks.

This is another installment of the PBS Deep Look series. If no film or link appears in this email, go to the blog to view it by clicking on the blog title above. If the film stops & starts in an annoying manner, press pause (lower left double bars ||) to let it buffer and get ahead of you.  [Chuck Almdale]
