Amphiprion perideraion

The relationship between anemone fish, Amphiprion sp., and their sea anemone partners are regulated by alkaloids from the sea anemone. Amphiprion perideraion is attracted to the sea anemone Radianthus kuekenthali by the simple lysine-derived alkaloid amphikuemin (Fig. 12.6 Murata etal, 1986). Other simple alkaloids, aplysinopsin and dihydroaplysinopsin, also attract A. perideraion, regulate its swimming rate and induce their species-specific partnership. A related anemone fish, Amphiprion ocellaris, is attracted to the sea anemone Stoichactis kenti by tyramine (Fig. 12.6) and tryptamine induces searching by the fish (Murata etal, 1986). 

C16H25N3O3, Mr 307.39. A., which is produced together with similar substances by the sea anemone Radian-thus kuekenthali, serves for mutual recognition and orientation in the symbiosis between the anemone and the anemone fish Amphiprion perideraion.
