The Mosasaurus is a minor anti-villain antagonist in the 2015 sci-fi adventure film Jurassic World and its 2018 sequel Jurassic World: Fallen Kingdom.

She is an individual Mosasaurus who is truly an eating machine with an endless hunger and can't have enough to eat to be satisfied. The Jurassic World employees only fed her during showtime, indicating they toyed with her appetite just for tourists to enjoy the show. The Mosasaurus has become ever alert for any fleshy living being to be unfortunate enough to fall into her water domains. When the island was abandoned, her hunger got worse to the point where she would eat anything that moved.

The Mosasaurus was created by InGen under the wing of the Masrani Global Corporation for their new dinosaur park Jurassic World and lived in a 3 million gallon pool of water located near Main Street known as the Jurassic World Lagoon. There, visitors could watch her feed on sharks during the Mosasaurus Feeding Show. Visitors could also view her through an aquarium below the lagoon known as the Underwater Observatory to see the Mosasaurus.

Jurassic World and Season 1 of Jurassic World: Camp Cretaceous

The Mosasaurus was first seen emerging from her lagoon, licking the roof of her mouth with her large tongue before catching a 9-foot great white shark on a large fishing line, and the audience, including Zach and Gray Mitchell, cheers. Then, the audience then gets an underwater tour of the Mosasaurus consuming the shark.

Following the escape of the Jurassic World Aviary's pterosaurs from their enclosure, Jurassic World employee Zara Young was dropped into the Mosasaurus's tank after being grabbed by a Pteranodon. The Mosasaurus stalked Zara as the Pteranodon flew over the enclosure to recapture her, then shot out of the water, catching both of them in her mouth. The Mosasaurus tasted Zara on her tongue and then closed her jaws on the Pteranodon. The marine reptile proceeded to devour Zara whole as she was in between the second row of teeth and went back underwater to digest her first human meal.

Afterwords, the same Mosasaurus circling around Darius Bowman and his group, Brooklynn, Kenji, Ben, Sammy and Yaz. The sea monster chased Darius and Sammy, while Yasmina distracts it, allowing them to escape. She grabs a mechanical chain to get to the land which is controlled by Kenji. As Yasmina makes it she breaks her ankle and drops the datapad in the water by accident. Later, at the end of the battle between the Indominus rex, the park's Tyrannosaurus Rexy and Blue, the Mosasaurus arose from the Lagoon to catch the hybrid in her jaws, and dragged her to the bottom of the lagoon to consume her as her midnight dinner, thus devouring her and saving the park in the process.

After the island is abandoned, the Mosasaurus is left in her lagoon never to be fed as her starvation becomes stronger.

Jurassic World: Fallen Kingdom and Season 4 of Jurassic World: Camp Cretaceous

Although the Mosasaurus was supposed to be dead, it was revealed that she has survived the months it has spent on Isla Nublar. While men in a submarine retrieved a sample of the skeleton of the deceased Indominus rex, the hungry Mosasaurus swallowed the craft whole as it departed. Then, she leaps from the water at an escaping helicopter and eats Jack, a mercenary. However, the lagoon doors are blocked and the Mosasaurus escaped into the open ocean.

Mosasaurus appeared only in the 1st episode of Season 4 of Camp Cretaceous. When Darius and the group are leaving the island, Mosasaurus is first seen ate white shark again, before chasing them on Mitch and Tiff's boat, and then lunged in a surprise attack, causing Yaz to attack with a kayak, but the Mosasaurus roared in the rage, bumped the boat, and then destroyed the boat, causing to sink to the ocean. Later on, the Mosasaurus appeared in Yaz's nightmare, breaking the iceberg.

The Mosasaurus only reappears at the end of the film, free in the ocean at last. She can be seen in the waves, stalking some surfers and licking the roof of her mouth with her tongue, hungrier than ever. One surfer wipes out and she advances forward through the waves as her jaws open. It is most likely she succeeded in devouring the surfer.

Battle at Big Rock

The Mosasaurus dosen't appeared in the short, but she appeared in the end credits, as a cameo. She can be seen ate great white with seal in it's mouth.

Jurassic World: Dominion

By 2022, the Department of Prehistoric Wildlife has confirmed sightings of the Mosasaurus somewhere in the Pacific Ocean, near San Francisco, in Seattle, in the corals of Hawaii, Okinawa, Japan, Lathryn's Hook, Alaska and Auckland, New Zealand where it teamed up with a pod of orcas to target great white sharks. As such, it could be suggested that the mosasaur may enjoy the company of cetaceans, as it was willing to work with them to hunt the same prey rather than kill and eat the orcas.

The Mosasaurus currently follows it main prey, the great white shark across their migration routes. In at the start of the film, the Mosasaurus is seen attacking a crab fishing boat in order to steal the crabs out of the baited traps, causing the boat to turn over, and the Mosasaurus either ate or injured the crew. Like the previous film, Mosasaurus reappears at the end of the film, was seen peacefully mingling with a pod of humpback whales.

Powers and Abilities


  • Mosasaurus Physiology: The Mosasaurus possesses incredible feats of strength, speed, agility, stealth, echolocation, senses and intelligence, even for a Mosasaurus as she is possibly more powerful than any other mosasaurs.
    • Aquatic Nature: Though technically a marine reptile, the Mosasaurus has an aquatic lifestyle like many mosasaurs. Although she lives her life in the water as she is able to stay underwater for long periods of time, she still needs to breathe air and has to surface periodically in order to breathe. The Mosasaurus is also capable of swimming by undulating her tail similar to modern alligators, crocodiles, other mosasaurs and sharks.
    • Enhanced Strength: Due to her ginormous size, the Mosasaurus is far stronger than other mosasaurs and most other dinosaurs; for example, she was strong enough to drag the Indominus rex into the depths of the Jurassic World Lagoon where she proceeded to devour the hybrid. She also has a particularly strong and powerful bite force of 33,000 pounds which she uses to bite down and kill her prey such as a Pteranodon and the Indominus rex.
    • Enhanced Speed: The Mosasaurus is much faster than other mosasaurs and most other dinosaurs; for example, she can swim as fast as a whale about 30 mph in the water.
    • Enhanced Agility: Like all modern land based predators such as lions and cheetahs, the Mosasaurus is quick and agile enough to take a deep breath for some sea animals to swim by and close enough to get sustained bursts of speed and agility to use quick acceleration to catch her prey.
    • Enhanced Senses: The Mosasaurus has senses that are far more greatly developed than other mosasaurs and most other dinosaurs; for example, she is able to pick up the scent of any prey that is above or below the water, particularly a shark, a Pteranodon and the Indominus rex.
    • Enhanced Intelligence: The Mosasaurus is far more intelligent than other mosasaurs and most other dinosaurs; for example, she was intelligent enough to know how to survive in the ocean after escaping from her enclosure.
    • Stealth: The Mosasaurus possesses brilliant stealth than other mosasaurs and most other dinosaurs; for example, she was able to wait until a Pteranodon was low enough over the lagoon or until the railing had been knocked away and the Indominus rex was within reach.
    • Echolocation: Like killer whales, the Mosasaurus has the ability to locate dinner and catch other animals in order to eat and survive including great white sharks, turtles, fish, plesiosaurs, and other small mosasaurs are potentially on the prey menu. She was able to use pressure wave sonar to detect by using keen sense of smell like modern day Komodo dragons.


  • Expert Tracker: Due to Mosy's senses of smell, she can find, spot or track things, including fish such as sharks and other prey in the water.


This Mosasaurus is a gigantic Mosasaurus who is much bigger than her extinct counterpart. She has flippers, a prehensile tail, a huge head with crocodile-like jaws lined with sharp teeth and in the roof of her mouth, spikes running down her back and a thick, heavy, average shaped tongue.

(Video) Jurassic World: Fallen Kingdom (2018) - Mosasaurus Attack Scene (1/10) | Movieclips


The Mosasaurus is a very large powerful aquatic predator who is at least as powerful as Rexy. Though judging by the body, her main attack is similar to Rexy such as her head and powerful jaws that they can both take down many prey that was proven by Indominus rex.

Sometimes, the Mosasaurus is known to swim up oceans and will hunt any kind of target that fits in her prey spectrum. Her color is ideal for her hunting strategy: she hunts from below and uses the element of surprise. the Mosasaurus could even leap out of the water to catch a falling target in her jaws and quickly devour it. Like Rexy, the Mosasaurus is also an animal who relies solely on her predatory instincts to survive.


  • Some fans have nicknamed the Mosasaurus "Shygal" because she was described as "shy" by Sarah, the feeding show announcer, others have chosen "Mosy".
  • An alternate opening for Jurassic World: Fallen Kingdom shows the concept art depicting the Mosasaurus after she escaped from her lagoon. She would have been hunting a pod of whales that was also being targeted by a whaling ship. the Mosasaurus would first snatch a harpooned whale, dragging the ship with it, then would have attacked and sunk the whaler. However, it was cut because it was very dark that the Mosasaurus would have destroyed an entire ship and killed many people.
  • Like Rexy and Blue, the Mosasaurus is also the last of her kind.
