Amphibian Reproductive Biology

Amphibian reproductive biology involves complex processes where most species reproduce through external fertilization. Males typically grasp females in amplexus to ensure sperm are released near eggs as the female lays them in water or moist environments. Eggs develop outside the body and hatch into free-swimming larvae called tadpoles, which later undergo metamorphosis, transforming into terrestrial or semi-aquatic adult frogs, toads, or salamanders. Some amphibians exhibit unique reproductive strategies, such as live birth or parental care. These adaptations help amphibians successfully reproduce in diverse habitats, contributing to their ecological diversity.
