Checklist of marine worms reported from Pakistani marine waters

Worm is generally used for naming all those animals crawling, wriggling and swarming. Any worm free-living or parasitic that lives in a marine environment is considered a marine worm. Invertebrate worms are important for the functioning of marine ecosystems in nutrient cycling through burrowing in sediment, release nutrients buried in the ocean bottom back to the surface for use by producers, in predator-prey relationships and as important links in food chains.
