T2 - Scientific Research Journal of Environment, Earth and Physical Science PY - 2025 VL - 3 IS - 2 SN - 2584-0614 AB - The Pantopoda, commonly known as sea spiders, has a significant impact on the equilibrium and diversity of aquatic ecosystems. This study elucidates their critical, yet frequently undervalued, roles within these environments. As pivotal predators of sessile invertebrates, sea spiders play a crucial role in regulating prey populations and shaping community dynamics. Their bioturbation activities facilitate enhanced nutrient cycling, and certain species uniquely engage in symbiotic relationships with methanotrophic bacteria, thereby assimilating methane-derived carbon into their tissues. This finding necessitates a reevaluation of marine food webs and has consequential implications for climate science. With over 1300 described species, sea spiders exhibit remarkable diversity across a range of habitats, encompassing both shallow coastal zones and deep-sea ecosystems. Nonetheless, populations of Pantopoda are increasingly threatened by climate change manifested through ocean acidification, elevated water temperatures, and habitat degradation, as well as pollution (including chemical contaminants, plastic debris, eutrophication, and acoustic disturbances) and overfishing practices such as bottom trawling, bycatch, and ensuing trophic cascades. In response, there is an urgent need for the implementation of effective conservation strategies. These should include the establishment of marine protected areas, continued research initiatives aimed at species identification and ecological functions, and assessment of the impacts of climate change. Furthermore, enhanced public awareness and education are paramount. Only through a concerted effort involving scientific inquiry, policy development, and public engagement can we safeguard the long-term viability of these crucial organisms and the health of the marine ecosystems they inhabit.
