David meeshiisii ahaa kalsooni ku qaba in kalluumaysatada, kuwaas oo aan khalad ah u tegi karto, sida ay u ogaadaan ka nibiriyada badda hoose iyo galayaan aad u wanaagsan yihiin. Qaabka kaliya ee ay hab-nololeedka ahaa shaqadan, oo garaadlaawaha todobaadle ah, mushaharka aad u yaraynaya, hadlay Muga. Waxaa laga yaabaa in ay dhab ahaantii ka adkaan kari waayeen cabsi ay qabsadey kulan lama filaan ah ula shark ah Rafaa Megalodon.
