The Family Centrolenidae, commonly known as glass frogs, is a group of small, primarily arboreal amphibians found in Central and South America. They are named for their translucent abdominal skin, which often allows internal organs to be visible. Glass frogs typically inhabit tropical rainforests near streams, where they lay eggs on leaves overhanging water so that hatched tadpoles drop into the stream below. They are mostly nocturnal, feeding on small insects, and are notable for their unique reproductive behaviors, including male parental care in some species. Their fragile habitats and sensitivity to environmental changes make them important indicators of ecosystem health.
