Ecology of Nematocarcinus gracilis
Main Ref. Poupin, J., 1998
Remarks Typically found near the sea floor in deep-seas. Its characteristic 3 pairs of extremely long, stilt-like pereiopods suggest its ability to walk on soft sediments. An opportunistic feeder, relying on phototrophically derived organic matter. Its feeding strategy may be assumed to be similar with its congener, N. exilis, a scavenger and predator that feeds mainly on fish remains and slow-moving benthic organisms. Shown to produce oval eggs (0.5 to 0.65 mm length) and may possibly achieve several reproductive outputs in its relatively long lifespan of 2 to 3 years (Ref. 97382).
