The importance of Sharks in the ecosystem is shown clearly here. The Orange Spine Surgeonfish (Naso lituratus), known locally as Erangl in Palau, aggregate to spawn during the last months of the year. The schools of fish attract the attention of the Gray reef sharks who pursue them relentlessly up and down the reefs, never giving their quarry a moment to rest. This pressure ensures the continued fitness of the Erangl by the loss of the weaker individuals to predation before they have a chance to breed.
Filmed 20th November, 2011 and 31st December, 2010.
