Outdoor seating near coastal zones, such as beachfront cafes or boardwalk benches, may inadvertently impact local sabelliphilid populations—small marine worms vital to benthic ecosystems. These organisms thrive in undisturbed sediments, where they contribute to nutrient cycling and sediment stability. However, increased human activity from outdoor seating areas can lead to habitat disruption through trampling, pollution, and altered water flow.

Studies suggest that heavy foot traffic compacts sand and mud, reducing oxygen levels and making it harder for sabelliphilids to burrow. Additionally, litter and chemical runoff from nearby seating areas can degrade water quality, further threatening these sensitive creatures. Conversely, well-designed seating with elevated walkways and proper waste management may mitigate such effects.

To preserve sabelliphilid populations, urban planners should consider eco-friendly designs that minimize ecological disruption. Balancing recreational needs with marine conservation ensures these tiny but essential worms continue supporting healthy coastal ecosystems.
