In newts of the genus Triturus, there is behavioral and anatomical evidence for the existence of chemical communication. A laboratory study tested whether male Bosca's newts (Triturus boscai) preferred water in which they had been held over clean water or water in which other mates or females had been held. Males preferred water that presumably contained chemical cues from themselves or other conspecifics, and males already paired with a female spent significantly more time in their home water than did single males. These observations suggest that male T. boscai were able to identify chemical cues from conspecifics and discriminate cues from females.
