20. It Came From Beneath the Sea (1955)
Full of hammy acting and ridiculous melodrama, It Came From Beneath the Sea makes the list for only two reasons: Ray. Harryhausen. The legendary stop-motion animation wiz provided the special effects in this early film that helped establish his name before he went on to Earth vs. the Flying Saucers, One Million Years B.C., Mysterious Island, The Seventh Voyage of Sinbad, Jason and the Argonauts and Clash of the Titans. The imagery of "it" -- a giant squid -- clinging onto the Golden Gate Bridge and later using its tentacle to crush people on a San Francisco street have become iconic in the realm of mega-creature features.

19. Ticks (1993)
18. Empire of the Ants (1977)
17. Anacondas: The Hunt for the Blood Orchid (2004)
16. Mosquito (1995)
What happens when mosquitoes feed on alien carcasses? A crappy movie; that's what! Bad action movie dialogue, awful acting, a corny sense of humor and outdated stop-motion animation combine for a campy good time, thanks to a nice level of gore, some frantic action sequences and the hilarious appearance of the rubber mosquito puppets. Plus, you get to see Gunnar Hansen (the original Leatherface from The Texas Chainsaw Massacre) handle a chainsaw one more time. Director Gary Jones might just be the modern Bert I. Gordon, scoring three campy films on this list. More »
15. Mimic (1997)
14. Tarantula (1955)
13. Rogue (2008)
Despite taking itself too seriously (It's from the guy who directed Wolf Creek, after all.) and featuring annoying characters who seem to want to get eaten, this Australian flick boasts possibly the most realistic fake crocodile ever filmed and has a classic climactic man-versus-beast battle.
