Images from Warmer Latitudes - Wetspot Images

Th worms in the sea are cooler than the worms on land.

This image is a close-up of the feathery branchiae on a type of tube worm I couldn't identify. These specialized "organs" serve double duty as both gills and hands, absorbing oxygen from the water as well as passing food to the worm's mouth down below. If disturbed, these fronds quickly withdraw into the worm's tube.
