Thresher Shark

The common thresher uses its elongated upper tail lobe to stun schooling fish in one of evolution's most remarkable hunting adaptations, and Ras Lima's fish-rich upwelling zones draw them in from the open ocean seasonally. Encounters typically occur in the 25 to 40 m range where cooler water masses meet the warmer surface layer. The Arabian Sea population is little studied and Musandam sightings contribute meaningful citizen-science data on their range and behavior.
