Today we saw our first basking shark of the year! These gentle giants follow the plankton bloom and migrate north as the seas warm up, so we usually see them in August or September. Despite their huge size (up to 14m) they are harmless as they only eat plankton by filter-feeding. They can filter thousands of gallons of water per hour. The view from land is usually of two fins; the dorsal fin and the tail fin. The shark we saw today had a very large dorsal fin so must have been pretty big.
