"One of the most interesting aspects of this expedition is the fact that the underwater ecosystem seems to be constantly changing. Tiger sharks are being spotted somewhat consistently. This is the first time these sharks have been seen in many years. What is bringing these sharks to the island? Temperature changes? Ecosystem shift? Longline bait from orphan fishing lines providing an easy meal? These large, reportedly aggressive sharks seem to be frequenting the Cocos Islets at night hunting the white tip shark populations that congregate there."
