Local fishermen at Malibu Pier received a surprise visit from a rare hammerhead shark. The shark was spotted circling the pier, causing a stir among those in the area. Unusually warm ocean waters are believed to be a factor in the shark's appearance, as they draw tropical marine life north.

This unexpected sighting has given fishermen a shock, and it remains to be seen if this is an isolated incident or a sign of more tropical species to come. Further details about the sighting are available from the Los Angeles Times, which reported on the rare hammerhead shark's appearance at Malibu Pier.
