kétéltben

Kétéltben is a Hungarian term that translates to "amphibian" in English. It refers to a class of vertebrate animals characterized by their unique life cycle, which includes both aquatic and terrestrial stages. Amphibians are known for their permeable skin, which plays a crucial role in respiration and moisture absorption, allowing them to remain moist and facilitating gas exchange. This skin also makes them particularly sensitive to environmental changes and pollutants.

The class Amphibia includes three main groups: frogs and toads (Anura), salamanders and newts (Caudata), and caecilians (Gymnophiona). Amphibians typically have larval stages that develop in water, such as tadpoles in frogs, which undergo metamorphosis to become land-adapted adults. This dual life cycle necessitates access to suitable aquatic and terrestrial habitats, influencing their distribution and ecology.

Amphibians are considered bioindicators due to their sensitivity to environmental disturbances. They play vital roles in ecosystems as both predators and prey, contributing to insect control and serving as food sources for higher predators. Many amphibian species face threats from habitat destruction, pollution, climate change, and emerging diseases like chytridiomycosis.

Conservation efforts focus on habitat preservation, pollution control, and disease management to address the global decline of amphibian populations. Their delicate skin and dependence on specific environmental conditions underscore their importance in monitoring ecosystem health and fostering biodiversity.
