fertilizing the eggs of several females. If it’s a dry night, the entire population will become inactive. The advertisement call of males are peeps between 4300 o 5300 Hz, around 0.1 seconds long, and 4 to 10 calls per minute, with no dominant frequency. A single peep will last about 0.4 seconds, which is then termed as a mew when a male discovers other frogs in his territory; this is called the encounter call. Male-male interaction Most of the time, calls are from the resident frog instead of the insider frog; physical contacts are uncommon. During mating season, the males would call out to the females, and once a relationship has been established, the highly territorial males would display another call to warn competitors away. Should any potential threats not back away, the frogs would fight until a winner is determined. The victor would be able to reproduce with the female. Male frogs have a noticeable hook protruding from its spine, presumably used to fight other frogs, or defend its territory or the eggs. They are fierce fighters who will occasionally engage in a wrestling matches with other intruding frogs. The female species are slightly larger and lacks this particular feature. Male-female interaction During the process of amplexus, males are stationary for the most of the time, which means they rarely start the amplexus. When entering the calling site of a male individual, a female will move up, down, and to the edge of the site while staring at the ground. The female will then continue to circle the male in a low, flattened posture. When the male detects the existence of the female, generally different types of calls will be given during the courtship. First, they will start with a mew interspersed with a shorter mew than the usual mew. Next, the male will exhibit the 0.1 second long chip call when male and female come to the surface of a leaf. If another female approaches, females won’t interact with each other. The late female will stop and find another calling male if the original male clasps the first female. Parental care Males’ involvement in parental care occurs at the stage of egg attendance. They assume a ventral contact by brooding, rotating, and manipulating the jelly of the clutch. Males manipulate the eggs in several ways, such as grasping the clutch from near the periphery and using their four
