Chengdu Institute of Biology has made new progress in the research on the evolutionary mechanism of animal multimodal communication

 The little turbulent frog lives in the streams in the tropical rain forest of Hainan Isla.

 First of all, the researchers constructed a map of the limb movements of the frog, and divided the limb display of the species into toe trembling ( TT , toe trembling ), hind foot lifting ( HFL, hind foot lifting ), waving ( AW, arm waving ), There are seven types of limb shaking ( LSA, limb shaking ), horizontal friction ( W, wiping ), leg stretching ( LS, leg stretching ) and semaphore ( FF, foot flagging ) (Figure 1.

 Taken together, this study shows that mosquitoes that feed on frog blood search for frogs by eavesdropping on the frog's call signals, and frogs defend themselves through complex body movemen.

 The research results were published in the international academic journal eLife under the title of " Parasite defensive limb movements enhance acoustic signal attraction in male little torrent frogs .
