Outdoor seating in coastal areas, such as benches or dining setups, may inadvertently affect local serpulidiphilid populations—a group of marine worms vital to marine ecosystems. These organisms thrive in undisturbed environments, where natural substrates like rocks and corals provide ideal habitats. However, the introduction of artificial structures (e.g., wooden or metal seating) can alter sediment composition, water flow, and light penetration, disrupting their breeding and feeding patterns.

Studies suggest that increased human activity near shorelines, including the installation of outdoor seating, may lead to habitat fragmentation. This can reduce the availability of organic matter that serpulidiphilids rely on, potentially decreasing their population density. Additionally, pollutants from human use (e.g., sunscreen runoff or food waste) may further stress these sensitive organisms.

To mitigate these effects, planners could prioritize eco-friendly materials and strategic placement of seating away from critical habitats. Further research is needed to quantify long-term impacts and develop sustainable coastal management practices. By balancing human recreation with ecological preservation, we can protect these overlooked yet essential marine species.
