Best Aquatic Horror Movies

This fun, fast-paced monster movie starring Corin Nemec as a fisherman battling semi-invisible sea creatures rises above typical TV or direct-to-video fare with ample low-brow action and gore.

Modern low-budget creature feature maestro Gary Jones (Mosquito, Spiders) directed this enjoyably cheesy, action-packed fare that's basically Die Hard in a swamp, as a group of robbers hijack a plane that ends up crashing in the feeding grounds of a monster croc.

It's a bit overrated, but this South Korean flick delivers genuine thrills (along with political and social commentary) and one of the best movie monsters in recent memory -- a huge amphibious cross between a fish and a lizard.

This surprise hit micro-budget pic is a terrifyingly realistic recreation of an actual event that happened when a boat mistakenly left a pair of scuba divers to fend for themselves in the middle of shark-infested waters.

Think snakes are land animals? These two films will have you more scared of encountering anacondas in the water than on land, provided you're swimming in the Amazon river or the jungles of Borneo.

Smart, genetically altered sharks are accidentally let loose in an underwater research facility in this fast and furious genre fare with blockbuster ambitions.

This tense thriller plays like an Australian Open Water, with a bigger body count and a bit more Hollywood-style action while still intimate enough to place you in the midst of the often-shocking action as a group of friends try to swim through shark-infested waters to an island after their boat capsizes.

Written with a deft comedic touch and featuring a star-studded cast that includes Bridget Fonda, Oliver Platt and Betty White, Lake Placid delivers more humor than horror as a 30-foot Asian crocodile finds its way to a rural Maine lake.

The pinnacle of SyFy creature features, this gory thrill ride finds genetically engineered, amphibious snakehead fish escaping from a shipwreck and terrorizing residents of a Louisiana swamp.

For my money, the most memorable story in this horror anthology sequel is the simple but effective "The Raft," based on a Stephen King short story about a group of friends who become trapped on a raft in a lake by a Blob-like man-eating creature resembling an oil slick.
