Ntsu ea Steller e boholo ba lisenthimithara tse 105. Lepheo le bolelele ba lisenthimithara tse 195 ho isa ho 245. Nako e bolelele e fihla ho cm 287. Boima ba nonyana e jang nama bo tloha ho ligrama tse 6000 ho isa ho tse 9000. Ena ke e 'ngoe ea lintsu tse kholo ka ho fetisisa. Litšobotsi tsa eona li bonoa habonolo ha li fofa ke mapheo a eona a ikhethang a bopehileng joaloka lesokoana le mohatla o molelele oa sebopeho. Malebela a mapheo ha a fihle ntlheng ea mohatla. E boetse e na le molomo o moholo, o hlahelletseng le o khanyang.
