Species Profiles: Life Histories and Environmental Requirements of Coastal Fishes and Invertebrates (North Atlantic) - Sandworm and Bloodworm

摘要

Species profiles are literature summaries of the taxonomy, morphology, range, life history, and environmental requirements of coastal aquatic species. They are prepared to assist in environmental impact assessment. The sandworm (Nereis virens) is a commercially valuable baitworm, reaching lengths of 30 cm. Most worms live 4 or 5 years. Males swarm in the water column before spawning in the females' burrows. Both males and females die after spawning. The bloodworm (Glycera dibranchiata), attaining lengths of 40 cm, is also an important baitworm. Its maximum life span is 5 years. Spawning occurs in the water column with both males and females dying after spawning.
