Ampharetids are detritovores and use their mouth tentacles to collect detritus particles. They inhabit soft sediments from intertidal to abyssal depths but are, in general, more common in deep waters. They live in tubes which they construct of sediment particles attached to a thin layer of secreted material. Ampharetids are an important part of the fauna associated with hydrothermal vents, for example Loki Castle vent field in the Norwegian Sea.
