Realm: Saltwater
Biome: Marine Shore, Seagrass Meadow
Introduction Method: Hitchhiker
Date First Introduced: December 10, 2023

Population Dynamics +

Current Estimated Population: 40
Population Status: Established
Carrying Capacity Status: At Capacity
Date Last Observed: June 10, 2026

Section Notes

Ragworms are established and confirmed breeding, with repeated burrow and sediment-disturbance context. Public records also place them near low-oxygen/worm-surfacing observations, but exact population trajectory remains unresolved.

Trophic Ecology +

Trophic Level: Omnivore
Feeding Niche / Method: Deposit feeding and omnivory
Dietary Inputs: Opportunistic omnivores, Algae consumers

Section Notes

Trophic classification is Omnivore. Food-web role: Burrowing omnivorous sediment consumer. Feeding method: Deposit feeding and omnivory. Dietary inputs: Opportunistic omnivores, Algae consumers

Environmental Tolerances +

Life Cycle & Reproduction +

System Reproduction Status: Confirmed Breeding
Growth Rate: Slow

Section Notes

It's believed they are successfully reproducing due to their large and established population. This species has been observed undulating their bodies outside their burrow at night which is know as a mating behavior.

Ecological Role & Symbiosis +

Marine/Saltwater

A marine meadow where seagrasses, macroalgae, grazers, filter feeders, worms, crabs, and small invertebrates compete over light, nutrients, and detritus.

Marine/Saltwater

A sandy, limestone shoreline where beach grasses, crabs, snails, and detritivores move nutrients across the waterline.
