Amphibian Facts

Here are some facts about amphibians:

• Diverse Species: Amphibians are a diverse group of animals that include frogs, toads, salamanders, and newts. There are over 7,000 species of amphibians found worldwide.
• Moist Skin: Amphibians have permeable skin that allows them to absorb water and oxygen directly from their environment. This makes them highly sensitive to changes in habitat quality and pollution.
• Metamorphosis: Most amphibians undergo metamorphosis, transitioning from aquatic larvae (e.g., tadpoles) to terrestrial adults. This process involves significant changes in body structure and physiology.
• External Fertilization: Many amphibians reproduce through external fertilization, where eggs are fertilized by sperm outside the female's body. This often involves elaborate courtship rituals and vocalizations.
• Semi-Aquatic Lifestyle: Amphibians typically inhabit both aquatic and terrestrial environments, depending on their life stage. They may breed and lay eggs in water, but adults often forage on land.
• Indicator Species: Amphibians are considered indicator species for environmental health because they are sensitive to pollution and habitat degradation. Declines in amphibian populations can signal broader ecosystem issues.
• Ecological Role: Amphibians play important roles in ecosystems as both predators and prey. They help control insect populations and serve as food for birds, mammals, and other predators.
