The Plesiosaur is a water-dwelling carnivore commonly found in deep ocean zones. It excels at underwater combat and traversal, making it a preferred mount for naval domination and deep-sea exploration. Players tame it to secure fast, stable aquatic transport and to defend underwater bases or ships from hostile creatures like the Mosasaurus.
It can be airlifted by Quetzal or Karkinos for fast deployment.

Taming a Plesiosaur requires knockout via tranquilizer. Use a Bow with Tranq Arrow or a Longneck Rifle for effective sedation. Superior Kibble is the best taming food, yielding the fastest results. Raw Mutton also works if kibble is unavailable.
About 27 Superior Kibble are needed. The process takes around 55 minutes and requires approximately 121 Narcotics. Use the calculator below for your settings.

The Plesiosaur takes +400% more damage from spike walls, making them extremely effective in defensive setups. It is also highly vulnerable to Instant HurtDinos and melee attacks with metal weapons. Conversely, it resists mining drill harvests completely and takes 50% less damage from explosions and certain ranged turrets.
The head is a weak point, taking 1.5× damage. All other body zones take standard damage. Aim for the head when knocking out or fighting a wild Plesiosaur.
