The underwater worm P. strickrotti belongs to the Nereididae household and is exclusive in comparison with its counterparts. In contrast to most ragworms that inhabit shallower waters, it resides within the bathypelagic darkness and is blind consequently. The worm’s parapodia, bristling with leg-like appendages, are lined with gills, a departure from the oxygen-absorbing parapodia present in different ragworms.
Nevertheless, the life cycle of the P. strickrotti underwater worm stays a thriller. The predominantly male specimens collected trace at a possible rarity amongst Nereididae, the place solely males might change into epitokes. Uncommon non-reproductive epitokous traits noticed within the males increase questions concerning the worm’s conduct and adaptation to its darkish habitat.
