Different Costa Rican populations have shown stability and, in some places, (Zarcero for example), the emerald glass frog is the most common glass frog within the area. [4] Moreover, it is shown to be common in Panama, Nicaragua, Ecuador and reasonably common in Honduras and Colombia. [4] It currently has a stable population trend and is not considered to be fragmented. [4] Strong site fidelity has been shown by the emerald glass frog, and its preferred system is terrestrial and freshwater. [4] As for the home range; the emerald glass frog shows strong fidelity within around 2 meters, and it is suggested that migration is a possibility. [7] Furthermore, studies have shown that the activity of males and females increased with rainfall. [10] Altitude Centrolene prosoblepon is found at elevations ranging from 20-1,500 meters in zones that are humid such as forests and rainforests. [5][3] It appears to be more common at higher altitudes due to the presence of more stream habitats near rivers and streams. [4] It has been found that the maximum elevation limit 1500 meters (above sea level). [4][3] In terms of habitat in these altitudes, the emerald glass frog prefers vegetated areas that are dense such as evergreen forests along banks of rapid streams where it breeds by laying its eggs on nearby leaves. [5] Behaviour The emerald glass frog's activity is nocturnal, and increased during rainfall.[6][10] Males are territorial and have high site fidelity which can lead to aggression. In the event of combat, males have humeral hooks that they use for grappling with other males. [6][4] Feeding Adults are carnivorous, primarily eating insects, whereas tadpoles can be both carnivorous and herbivorous. Tadpoles eat algae, aquatic invertebrates as well as other tadpoles. [7] Fighting Male emerald glass frogs have large humeral spines that they use for combat. The size varies amongst individuals and tends to be correlated with who wins the interaction. [9] If a male's territory is encroached upon the two males will engage in a grappling match that can last up to 30 minutes. [5] This is more common in areas of high male density than in areas of low male density. [9] Males in combat hang by their toes on the same or nearby vegetation and seize each other front to front, hooking their humeral hooks in the other's axial region. When this ritual is over, the males may make a peep
