Emerald glass frog (Espadarana prosoblepon)

The emerald glass frog is a species of frog in the family Centrolenidae. This species can be found in Ecuador, Colombia, Panama, Costa Rica, Nicaragua, and Honduras. Its natural habitats are lowland tropical forests and montane cloud forests. It is a nocturnal species occurring in low vegetation in mature forests only. It is physically described to be small, green, and may occasionally have dark spots on its back. It has a translucent body for camouflage, green bones and both males and females have humeral hooks (larger in males) which they use for fighting. Females generally exhibit less parental care than males do. A female may remain near her eggs for a period of time up to several hours after deposition, but males have been reported to guard the eggs as they guard their territory. There has been no evidence that female parental care benefits the clutch, whereas male parental care has been seen to increase success.
