Amehlo enhlanzi awathandeki kahle ngenxa yokuthi ihlala njalo emathunjini amnyama amadamu. Kodwa inenethiwekhi eyakhiwe kahle yama-sensors-receptors asetshenziswa ushaka lapho efuna ukudla.
La ma-receptors atholakala ngoqhwaku lwawo olukhulu futhi angazizwa isisulu ebumnyameni obuphelele bolwandle amashumi ngamamitha ambalwa. Ushaka unesakhiwo somhlathi okhethekile namazinyo aqinile kakhulu. Umane akwazi ukudonsa amagobolondo aqinile namathambo amakhulu.
Le nhlanzi ayivamisile ukubamba isisulu sayo. Idonsela emanzini endaweni lapho umamukeli kashaka akhombisa khona ukuthi kungenzeka kube khona isisulu.
