These shrimp are soft-shelled, and small to medium-sized. The pleura of their second abdominal segment overlaps with the adjacent segments. Their first two pairs of pereiopods are similar, with an unsegmented carpus and ending in chelae (pincers), unlike the third pair which lack chelae. The last three pairs of pereiopods (sometimes the second as well) are very elongate, hence the name (nemato-; thread). Exopods are present on the first to fourth pairs of pereiopods. Shrimp of this family range in color from pale orange to deep red.
