What are the longest animals in the world? Hint: you’ve most likely never heard of them. They glow in the dark and have many stomachs, mouths and tentacles – sometimes hundreds. They’re about the width of a broomstick, but they can grow to be more than 100 feet long. So although blue whales are bulkier, some species of this marine animal are longer.

They’re called siphonophores (that’s pronounced sigh-FAWN-oh-for) and they’re cousins to the jellyfish you can see at the Monterey Bay Aquarium. Aliens, giant caterpillars, tropical flowers: siphonophores resemble all three. And in today’s QUEST television story you’ll have a unique opportunity to see footage of the siphonophores that live in the Monterey Bay, courtesy of the Monterey Bay Aquarium Research Institute.
This week’s story also features a behind-the-scenes visit to the Monterey Bay Aquarium’s jellyfish exhibit. And I can promise you that you’ve never seen the orange sea nettles in the giant blue tank quite like you’ll see them in this story.
