Geed illaa 9 m ah, oo leh laamo cufan oo koofiyad duuduudan oo soo foorarta leh, oo laamaha baalluhuna ay xaglo leeyihiin kana kooban yihiin qaybo; oo qodxuhuna ay madax yeelanayaan iyaga oo ka sii dul baxaya xaglaha laamahaas. Wuxu leeyahay dheecaan sun ah. Caleemuhu si dhakhso ah ayey u daataan. Ubaxiisuna waa dahabi hurdi ah oo iyaga oo isku xoonsan ka baxa dhammaadka laamaha. Midho ku jira dahaadh hilboon oo casaan isku beddelaya, kadibna adkaanaya oo deetana kala baxaya si ay u sii daayaan iniinyo fiican oo dameeri ah.
