size does not seem to be correlated with mating success, larger females tend to lay clutches with more eggs in them. This reproductive behavior is generally constant throughout emerald glass frog's range. [10] Development These frogs begin as eggs laid on land, develop as aquatic tadpoles, then return to land in their adult life stage. After deposition, the eggs take 8–20 days to develop. Tadpoles drop into the water underneath them and are often born when it is raining, which is said to be a camouflage technique. The hatchlings are 12mm in length, and have specialized mouth parts for attaching to substrate in the stream. After hatching they congregate and remain in the leaf litter and sediment for several months and once they are fully developed into adults they become terrestrial animals. [7][8] Egg clutches Eggs are laid in clutches of 10 to 40 eggs and are black in color, and each about 10mm in diameter. [8][5] The eggs are deposited together and form a jelly covered monolayer that is usually about 50 mm in diameter. [5] Parental care 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. [7] Habitat Emerald glass frogs prefer humid terrestrial or aquatic habitats in rainforests and wet forests. They have both terrestrial and aquatic life stages, so they tend to live in vegetation beside streams. They prefer shallow streams because there are more rocks and logs that have vegetation on them for depositing eggs, where less flooding occurs. [6][7] Distribution and Range The range of the emerald glass frog is from eastern Honduras, Nicaragua, Costa Rica, and Panama, to the Pacific slopes of Colombia and Ecuador. [6][4][5][3] In Colombia, it is found in the northern and eastern areas (along Cordillera Oriental and in the Magdalena Valley). [4][3] It is also found along the Caribbean and along the Pacific slopes. [5][3] It is frequently recorded in Costa Rica. [4] It has declined drastically in Monteverde, Costa Rica since the mid 1980s. [4] While this may require further investigation, recorded declines in Costa Rica might be due to the chytridiomycosis disease. [4]
