Anemonoid appeared in 2009 literature called James Cameron's Avatar: An Activist Survival Guide. The anemonoid (Na'vi name: fyuatx) (scientific name: Cataracta anemonica or "waterfall anemonoid") lives in ponds and lakes. It is an invertebrate-like creature with small, toxic tentacles for feeding. Bioluminescence in myriad pastel colors. Small fish are attracted by bioluminescence into tentacles and eaten. Anemonoid line the dense forest floors and waterways, providing the most light in the night landscape on Pandora.
