“…In the Romanche Trench, where the neotype was collected, the substratum has variously been described as erosional sands (Heezen & Laughton, 1963) or ooze (Cifelli, 1967), and the minimum bottom temperature was about 0.7 o C (Morozov et al, 2010). However, from what is known about other deep-sea enteropneusts (Smith et al, 2005;Holland et al, 2009Holland et al, , 2012aAnderson et al, 2011;Priede et al, 2012), G. abyssicola is very likely a deposit feeder, although nothing is yet known about how selective it might be.
