4. Scuba Zombie
as seen in
Zombie Flesh Eaters (1979) Scuba diving, though fun, can be dangerous. Theres your oxygen to worry about and whole assortment of deadly fish lurking down their below the waves. When Susan strips off and goes for a dive, she is terrified to find the waters shark infested. Even worse, theres a dead man walking down there. Perhaps lured on by the challenge, the zombie goes for the shark, and gets in some good bites before his arm is bitten off. An amazing and off-the-wall sequence that they just dont shoot nowadays.
