Movie Monster Wiki

The Mutant Mako Sharks are the main antagonists of the 1999 American horror film Deep Blue Sea.

Secretly and illegally genetically engineered with larger brains in order to harvest brain chemicals that could help cure Alzheimer's in humans, these sharks have near-human intelligence and are therefore much more dangerous than your typical shark.


The Mutant Mako Sharks are three large hyper-intelligent shortfin mako sharks. The trio are composed of two twin male Generation 1 modified sharks and a Generation 2 genetically engineered female. The small sharks stretch 9-13 feet, while the big shark measures in as a massive 26 feet in length.

Powers and Abilities

The Mutant Mako Sharks possess the following powers and abilities:

  • Sharp teeth
  • Enormous size
  • Increased intelligence
  • Ability to swim backwards


After ravaging the sinking base that birthed them, the first of the sharks, one of the twins, dies from the station's cook causing a gas line explosion in the flooded kitchen. The second shark is electrocuted by the chief geneticists when she throws a power cable into the flooded room it was swimming in. The Generation 2 shark is killed by the combined efforts of the cook and station's shark wrangler attaching an explosive harpoon to it.


  • The animatronic sharks are three. The smaller sharks used in the film were scaled to be 13 feet, while the larger animatronic shark was made to be 26 feet in length to one-up Jaws, who's shark was 25 feet for the film.
  • The Gen 2 female shark's massive size of 26 feet and 8,000lbs is a hint the sharks were genetically engineered as Shortfin Mako Sharks rarely exceed 13 feet in length and under 500lbs.
  • The trio were killed in almost the exact same way that the sharks in Jaws, Jaws 2 and Jaws 3 met their ends. The first and third shark were blown up, with the second being electrocuted.
