Larval Arizona tiger salamanders (Ambystoma tigrinum nebulosum) can discriminate between kin and nonkin (Pfennig et al. 1994). In experimental tests, cannibalistic morphs may prey preferentially on unrelated individuals over related ones. The sensory basis for this discrimination was examined by covering the nares of test animals with Vetbond (3M Animal Care Products), an w-butyl cyanoacrylate tissue adhesive. This material blocks the passage of water over the nasal epithelium. In tests, some animals had their nares blocked, while sham controls had the adhesive placed between their nares. Larvae whose nares were blocked consumed kin and nonkin randomly. Animals without their nares blocked consumed more nonkin than kin. These results suggest that discrimination is based on chemical cues.
