MMOs similar to The Isle

The Isle is a hardcore survival game about living out a dinosaur's entire life — from a defenceless hatchling to a full-grown predator or towering herbivore — built around permanent death and a species-specific feeding system.

These picks share the core idea of inhabiting a living ecosystem as an animal rather than matching the setting on the surface. Some lean toward gentler progression and quests, others toward taming and base-building, and one mirrors the growth mechanics closely but currently draws a much smaller crowd on its servers.
