The most eurythermal metazoan?
It is a polychaete.
Cary,SC; Shank,T; Stein,J (1998): Worms bask in extreme temperatures.
Nature 391(6667), 545-546 (5 Feb issue. Scientific correspondence).
In situ temperature records in tubes of Alvinella pompejana living on
sides of hydrothermal vent chimneys show an average of 68 deg C, with
spikes exceeding 81, whereas tube opening (on outside of chimney) temp is
22 deg C. This makes Alvinella the most thermotolerant and eurythermal
(The authors also refer to Pierre Chevaldonne's & D. Desbruyeres' 1992
note in Nature.)
