Akupara 81, also referred to as the Archelon defense project, is a purple Archelon with large spikes down its shell and head, and with some spikes on its fins. It has "cracks" in which light will occasionally flash and also has electricity pulsing from the animal as seen when it swims, attacks, gets up, or roars. It is unknown if Akupara 81 is a hybrid or simply a genetically enhanced Archelon. Its only appearance so far is Jurassic World: The Game.
Akupara 81 was added to the game on May 25, 2019, as an area boss.
The Akupara 81 starts out with 6,289 HP but only 350 damage per hit to possibly make Akupara 81 easier to fight against. Each time it is beaten, it revives with twice the amount of HP and damage. It repeats this until it defeats every dinosaur in the player's party. The purpose of this battle is not to defeat the Akupara 81, but to deal as much damage as possible.
The best strategy to deal as much possible damage to Akupara 81 is different to defeating enemies in the live arena. it is best to reserve at first and attack heavily since Akupara 81 blocks much less than opponents in the live arena due to the fact that he can not lose. It is also wise to have a meat shield and 2 heavy attackers to deal damage while the meat shield absorbs damage and buys time to reserve actions. It is also advised to be more defensive to protect from Akupara 81's heavy hits and since Akupara 81 reserves more and blocks less since it can not lose.
- The name Akupara originates from the Hindu mythological creature of the same name, also known as the world turtle. This creature is believed to be a giant turtle or tortoise that holds up the Earth on its back, preventing it from falling.
