Leedsichthys
Leedsichthys Overview
Leedsichthys is an aquatic carnivore in ARK: Survival Ascended, roams the ARK as a wild, untamable creature. Leedsichthys cannot be tamed through conventional methods and is encountered with 1800 base Weight, providing an enormous weight pool. It gives live birth after a gestation period, with offspring maturing over an extremely long period, one of the longest in the game. Its harvest profile centers on Hide, Raw Prime Fish Meat, making farming runs noticeably faster. That combination of survivability and damage is why Leedsichthys sits on most endgame mount shortlists.
