chunk: With the Orca slowly sinking, the trio attempt a riskier approach: Hooper dons scuba gear and enters the water in a shark-proof cage, intending to lethally inject the shark with strychnine using a hypodermic spear. The shark demolishes the cage before Hooper can inject it, but he manages to escape to the seabed. The shark then attacks the boat directly, crushing the transom and devouring Quint. Trapped on the sinking vessel, Brody stuffs a pressurized scuba tank into the shark's mouth, and, climbing the mast, shoots the tank with a rifle. The resulting explosion obliterates the shark. Hooper resurfaces, and he and Brody paddle to Amity Island clinging to boat wreckage.
