Particle-size utilization in the deposit-feeding polychaete Neanthes
succinea was examined. Gut analysis revealed that worms in San Francisco Bay
consumed a broad range of particle sizes (20-300mm diameter). Gut sediment
closely resembled size of surface sediment at the mouths of worm burrows
. indicating non-selective feeding. All size classes of worms consumed similar sized
particles. The flexibility in feeding modes and diet of nereids is discussed
