- Umlomo okhethekile: Own ukumunca umlomo wenkomishi, enezintshebe ezimbili noma ama-barbel asebenza njengezinzwa, alungele ukuthola ukudla ngaphansi kwamanzi.
Le nhlanzi ayisebenzi kakhulu futhi ngokuvamile ihlala inganyakazi isikhathi eside, okuyivumela ukuba yonge amandla futhi ibambe inyamazane yayo kalula.
Indawo yokuhlala nokusatshalaliswa
