Nereis - The Clam Worm Or Sandworm. Nereis or Neanthes is a marine polychaete annelid that lives in burrows in sea bottom and comes out in night to prey upon small animals. N. virens (Sandworm), N. pelagica (Type-species) and N. succinea (Clam worm) are common species of Nereis.

Nereis pelagica can be distinguished from N. zonata by the four large conical paragnaths in Area VI on the pharynx, while N. zonata has six small conical paragnaths. In the anteriormost chaetigers the parapodial ligules are rounded in N. pelagica, while they are pointed in N. zonata. Nereis pelagia is similar to Hediste diversicolor in general.

ABSTRACT. The rates of oxygen uptake of the marine polychaete Nereis pelagica and the bivalve Arctica islandica depend on the availability of ambient oxygen. This is manifest both at the tissue level and in isolated mitochondria studied between oxygen tensions of 6.3 and 47.6 kPa (47-357 mmHg).

Polychaeta

Mating: Females produce a pheromone attracting and signalling the males to shed sperm which in turn stimulates females to shed eggs, this behavior is known as swarming. Gametes are spawned through the metanephridia or body wall rupturing (termed as "epitoky", wherein a pelagic, reproductive individual, "epitoke", is formed from a benthic.
