摘要：

Temperature is one of the most important environmental factors that governs a species' distribution. Some highly specialized prokaryotes can grow at temperatures above 113 °C (ref. 1), but eukaryotes appear less versatile2 and do not normally occur above 55 °C. Here we show that a colony-dwelling polychaete worm, inhabiting deep-sea hydrothermal vent chimneys, regularly experiences temperatures above 80 °C and a thermal gradient of 60 °C or more over its body length.
