Hottie Alert! by Christina Kellogg

Move over Angelina Jolie-according to University of Delaware marine biologists, the Pompeii worm is “Earth’s Hottest Animal.” And how could it not be…an invertebrate with a pimp-tastic bacteria fur coat?! Well that, and it can survive even when its butt is bathed in hydrothermal vent fluids as hot as 176˚C.

“While some bacteria thrive at higher temperatures, the Pompeii worm ranks as the most heat-tolerant among complex life forms. The former record holder was the Sahara Desert ant, at 131°F. Discovered in the early 1980s by French scientists, the Pompeii worm (Alvinella pompejana) is about 4 inches long with tentacle-like, scarlet gills on its head. A gray “fleece” of bacteria covers the worm’s back. The worm gets its name from the Roman city of Pompeii, which was destroyed during an eruption of Mount Vesuvius in 79 A.D. The Alvinella in the worm’s scientific name stems from the submersible Alvin.
The Pompeii worm and its bacteria are of interest to industry, as well as the scientific community, because they may yield a variety of products and applications, from new pharmaceuticals to enzymes capable in operating in hot, corrosive, high-pressure environments. Such enzymes can help dislodge oil inside wells, convert cornstarch to sugar, process food and drugs, and support a number of other industrial processes by speeding up chemical reactions.”

Craig McClain is the Assistant Director of Science for the National Evolutionary Synthesis Center, created to facilitate research to address fundamental questions in evolutionary science. He has conducted deep-sea research for 11 years and published over 40 papers in the area. He has participated in dozens of expeditions taking him to the Antarctic and the most remote regions of the Pacific and Atlantic. Craig’s research focuses mainly on marine systems and particularly the biology of body size, biodiversity, and energy flow. He focuses often on deep-sea systems as a natural test of the consequences of energy limitation on biological systems. He is the author and chief editor of Deep-Sea News, a popular deep-sea themed blog, rated the number one ocean blog on the web and winner of numerous awards. Craig’s popular writing has been featured in Cosmos, Science Illustrated, American Scientist, Wired, Mental Floss, and the Open Lab: The Best Science Writing on the Web.
