Tunnicliffe, Verena J., Desbruyères, Daniel, Jollivet, Didier and Laubier, L. 1993. 4 to In the early stages of high temperature deep-sea hydrothermal vent chimneys growth, the walls remain porous and allow the escape of hydrothermal fluids as well as an inflow of seawater. the first 24-30 of which have only notopodia var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s); strongly modified into 4-5 very large, strong hooks which arise from POM A similar situation was also depicted for the sulphide worm Paralvinella sulfincola for which temperatures up to 45°C have been recorded around the tubes of the worms in the northeastern Pacific . Geographical Range:  The upper thermal limit for this polychaete is unknown; however, it is unlikely they can survive in constant temperatures over 50 °C. One other possibility for worm migration is the decrease in food availability in the worm’s general area. Paralvinella sulfincola. (photo). Under laboratory conditions, in a pressurized aquarium with a heat gradient, worms of the species Paralvinella sulfincola, chose water heated to 122 °F (50 °C) and made brief forays into water as hot as 131 °F (55 °C).
