Feeding:

    

 

Adults from Arctic deep-sea sites are facultative predators of other nematodes; the intestines have a number of partially degested nematode prey as well as spicules of prey nematodes.  Younger juveniles appear to feed on dissolved organic material and decaying organisms. Some juveniles observed with bodies of several Thalassomonhystera , especially T. molloyensis, in the intestine (Fonseca and Gallucci, 2008).
