Tortoise Survival and Development

A newly hatched tortoise emerges from its nest, the last of its clutch. With its mother gone, it must navigate the world alone, relying on the remnants of its yolk sack. The hatchling faces numerous challenges, including predators and the need to find a new shelter. Its soft shell makes it vulnerable, and only a small percentage of hatchlings survive to adulthood.
