When it comes to the fastest water animals in Ark, there is no clear answer, as several species can claim the title. However, there are two contenders for the title of fastest swimmer in the game – the Sarco and the Megalodon.
The Sarco is a large predatory fish which lives in the waters of the island. It is the fastest swimmer in the game, able to reach speeds of up to 50 mph. It is also one of the most dangerous creatures in the game, and is not to be taken lightly.
The Megalodon is a huge shark which can be found in the deep ocean. It is an incredibly powerful predator, and is capable of swimming at speeds up to 40 mph. It is one of the most powerful creatures in the game, and should be avoided if possible.
Both of these creatures are extremely fast, and can be found in the depths of the ocean. They are both incredibly dangerous, and should not be taken lightly. It is difficult to determine which is the fastest, as both can reach extremely fast speeds. However, the Sarco is likely to be the faster swimmer of the two.
