The plot revolves around a military experiment gone wrong, where genetically modified piranhas escape into a river near a summer resort. As the carnivorous fish wreak havoc, a pair of unlikely heroes must stop the chaos before the body count rises.

While clearly inspired by Jaws, Piranha carves out its own identity with impressive practical effects, satirical undertones, and relentless thrills. It remains one of the most beloved animal attack movies of all time.

3. Piranha Sharks (2014)

Genres: Horror Comedy, Sci-Fi, B-Movie

Why You Should Watch: For fans of so-bad-it’s-good cinema, this indie flick offers a ridiculous yet entertaining take on the piranha genre. Instead of standard man-eating fish, the film introduces genetically engineered, miniature piranha-sharks that infiltrate New York City’s water supply.

Directed by Leigh Scott, Piranha Sharks is an absurd yet oddly compelling mix of sci-fi horror, political satire, and ridiculous action sequences. If you enjoy B-movies with intentionally cheesy dialogue and over-the-top special effects, this one's for you.

4. Mega Piranha (2010)

Genres: Sci-Fi, Horror, Action, B-Movie

Why You Should Watch: If campy disaster films are your thing, Mega Piranha delivers exactly what you'd expect—giant, mutated piranhas attacking everything in sight. Starring ’80s pop star Tiffany and Barry Williams (The Brady Bunch), the film follows a team trying to stop these oversized fish before they reach Florida’s coast.

With exaggerated action sequences, questionable CGI, and a wildly dramatic plot, this film embraces its low-budget absurdity, making it an ideal choice for lovers of intentionally over-the-top monster movies.

Cast: Tiffany, Barry Williams, Paul Logan

Directed by: Eric Forsberg

5. Piranha II: The Spawning (1981)

Genres: Horror, Thriller, Sci-Fi

Why You Should Watch: Did you know James Cameron’s directorial debut was a piranha movie? Piranha II: The Spawning takes the killer fish concept to new heights—literally—by introducing piranhas that have evolved to fly.

While it’s far from Cameron’s best work, this film is a fascinating watch for fans of his later blockbusters like The Terminator and Aliens. It mixes suspenseful aquatic horror with outlandish sci-fi elements, making it an interesting entry in the piranha movie lineup.

Cast: Lance Henriksen, Carole Davis, Ricky Paull Goldin

Directed by: James Cameron, Ovidio G. Assonitis

6. Piranhaconda (2012)

Genres: Horror, Sci-Fi, B-Movie

Why You Should Watch: What’s scarier than a piranha? A piranha-anaconda hybrid. This SyFy original movie, directed by B-movie legend Jim Wynorski, follows a film crew stranded on an island where two massive, slithering fish-serpents hunt their prey.

With Michael Madsen and Rachel Hunter leading the cast, Piranhaconda embraces its ridiculous premise, delivering over-the-top monster action, exaggerated CGI effects, and laughably dramatic performances. Perfect for fans of so-bad-it’s-good creature features.

7. Piranha (1995)

Genres: Horror, Thriller, Cult Classic

Why You Should Watch: A made-for-TV remake of the 1978 classic, this version modernizes the story with updated visual effects and a new setting. Following a group of teens who stumble upon a government experiment gone wrong, the film brings fresh energy to the franchise.

While it may not surpass the original, it delivers solid suspense, atmospheric underwater cinematography, and intense action, making it a worthwhile watch for die-hard piranha movie fans.

Fun Fact: This film marks the acting debut of Mila Kunis.

8. Piranha 3DD (2012)

Genres: Horror Comedy, Thriller, B-Movie

Why You Should Watch: The bigger, crazier sequel to Piranha 3D takes the action to a water park, where prehistoric piranhas turn a summer attraction into a bloodbath. Featuring hilarious cameos from David Hasselhoff and Christopher Lloyd, this film leans into absurdity while still delivering its fair share of gore.

If you enjoyed the first film’s mix of horror and comedy, Piranha 3DD offers even more chaos, campy fun, and over-the-top kills.

9. Piranha-Man vs. Werewolf Man: Howl of the Piranha (2010)

Genres: Horror, Action, B-Movie

Why You Should Watch: If you’re looking for the ultimate piranha-themed oddity, this ultra-low-budget indie flick pits a half-man/half-piranha against a werewolf in a wildly ridiculous creature-feature showdown.
