Why do the eggs of amphibians dry out so easily?

Amphibian eggs are typically laid in moist environments, such as water or damp soil, because they lack a protective shell that can prevent desiccation. Their gelatinous outer layer provides some moisture retention but is not sufficient to protect against drying out in arid conditions. Additionally, amphibian eggs are often exposed to environmental factors like sun and wind, which can further accelerate evaporation. As a result, they are highly susceptible to drying out if not kept in a suitable habitat.
