It dwells within tubes in waters surrounding hydrothermal vents, in close proximity to super-heated fluids reaching over 300 �C . The upper thermal limit for this polychaete is unknown; however, it is unlikely they can survive in constant temperatures over 50 �C . It may tentatively be named a metazoan extremophile or, more specifically, a thermophile.

It is distinct from Italian ricotta because ricotta ( yogurt cheeses such as the South Asian " chak ( k ) a ", the Arabic labneh, and the Central Asian suzma or kashk, but while these products are obtained by straining yogurt ( milk fermented with thermophile bacteria ), quark is made from soured milk fermented with mesophile bacteria.
