Definition
Amphibians are a class of cold-blooded vertebrates that typically undergo a life cycle involving both aquatic and terrestrial stages, characterized by moist skin, the presence of lungs in adults, and the ability to reproduce in water. This group includes frogs, toads, salamanders, and newts.
Summary
Amphibians are a unique group of cold-blooded vertebrates that play essential roles in ecosystems. They undergo a fascinating life cycle that includes metamorphosis, transitioning from aquatic tadpoles to terrestrial adults. Their diverse habitats and adaptations allow them to thrive in various environments, making them important indicators of ecological health. However, amphibians face significant threats, including habitat loss, pollution, and climate change, leading to declining populations. Conservation efforts are crucial to protect these species and maintain biodiversity. Understanding amphibians helps us appreciate their role in nature and the importance of preserving their habitats for future generations.
