Poor old basking shark
The shark which is harpooned is a basking shark.
Its gaping mouth is visible underwater just before it is speared. The gaping mouth gathers plankton from the water.
See http://en.wikipedia.org/wiki/Basking_shark
They are slow-moving and un-aggressive.
I would say the shark hung on the crane is one also, it has had a huge set of false teeth added to add to the horror.
