HISSING AS A MULTIFUNCTIONAL AND INTERSPE CIFIC SIGNAL OF ANIMALS

Hissing signals were studied in various groups of animals: insects, re ptiles, mammals, and birds. Hissing was analyzed using a computer-base d acoustic analyzer KAPROS-01. General similarities of hissing were no ted for representatives of taxonomically remote orders and classes, as well as evident structural differences, not always related to the abs ence of taxonomic relatedness of the given species. Bioacoustic parall elisms of hissing were shown, which are based on threatening signals f rom animals with ecological weapons, such as poison, sharp teeth and c laws, etc. Multifunctional and interspecific patterns of hissing were noted aswell as its ecological-communicative role in biocoenotic relat ions between animals of different groups.
