Genus Phyllomedusidae. are slender frogs that have many different color combinations. They are small-to-medium-sized frogs that are ectothermic and exhibit bilateral symmetry. This genus includes tree frogs because they are primarily arboreal. They are predominantly green on their dorsal sides and have yellow/orange color on their ventral sides. This coloration camouflages them with leaves and other vegetation. Some species like Agalychnis lemur can have different coloration, such as exhibiting an orange dorsal side. All species have rather large eyes that protrude from their craniums. Their limbs are long and some have webbing between their toes. ("Amphibia Web", 2022)is made up of 14 species in the family
Agalychnis lemur) wherein they change from a green color during the day into reddish-brown or even orangish-tan at night. On their ventral side, they can have many different yellow, white, or orange shades. Their size can range anywhere from 30mm-88mm. Their appendages are long and slender, with a slender, flattened body and a depressed head. Their eyes are rather large and protrude out of their heads, which have lower eyelids. Most of these frogs' skin, both ventrally and dorsally, is smooth but some have rough warts. frogs' heads are round and they have a short snout when looked at from above. ("Amphibia Web", 2022)frogs have webbing in-between each of their toes and suction disks at the ends of their digits. Body-color ranges anywhere from light green to dark green on the dorsal side. Some frogs are even able to exhibit metachrosis (i.e.
A. spirrelli) to 47-162 eggs (i.e. A. annae) in a single clutch. Eggs then hatch into tadpoles around 6-14 days after being laid. Some species show plasticity while hatching. A. callidryas can undergo synchronous hatching when disturbed by predators or fungus. These tadpoles then develop in pools of water, where they are laid in leaves that overhang the water body. They are then independent of their parents, and the ones that survive undergo metamorphosis to transition to terrestrial life. (Cossio and Medina-Barcenas, 2020)frogs can lay anywhere from 14-67 eggs (i.e.
A. callidryas have also been observed to use vibration-based communication when males have territorial disputes. Specifically, one male will vibrate tree branches until the submissive male gives up that territory to the victorious male. (Cossio and Medina-Barcenas, 2020)frogs are social and have different croaks/calls with varying lengths or pitches to communicate location, territory, and mating rituals. They also rely on their vision to scan the environment for mates and predators.
Humans can use A. callidryas is also very popular in the pet trade. Their bright colors make them a popular animal for people to want in their homes. ("Amphibia Web", 2022; IUCN SSC Amphibian Specialist Group (IUCN SSC), 2016)frogs to determine the health status of their environments. Since they are sensitive to changes in the environment, it is easy to tell how well an ecosystem is doing by studying these frogs. frogs also control insect populations, which consequently reduces the spread of disease.
There are no known adverse effects ofon humans.
The conservation status of A. callidryas. This genus is also found in many protected areas of wilderness. (IUCN SSC Amphibian Specialist Group (IUCN SSC), 2016)is Least Concern. However, the populations of this genus are declining. This is because of the expansion of infrastructure, logging, and agricultural activities. frogs populations are also declining because of their popularity in the pet trade, especially

Referring to an animal that lives in trees; tree-climbing.
having body symmetry such that the animal can be divided in one plane into two mirror-image halves. Animals with bilateral symmetry have dorsal and ventral sides, as well as anterior and posterior ends. Synapomorphy of the Bilateria.
an animal that mainly eats meat
to jointly display, usually with sounds, at the same time as two or more other individuals of the same or different species
having markings, coloration, shapes, or other features that cause an animal to be camouflaged in its natural environment; being difficult to see or otherwise detect.
animals which must use heat acquired from the environment and behavioral adaptations to regulate body temperature
forest biomes are dominated by trees, otherwise forest biomes can vary widely in amount of precipitation and seasonality.
mainly lives in water that is not salty.
An animal that eats mainly insects or spiders.
A large change in the shape or structure of an animal that happens as the animal grows. In insects, "incomplete metamorphosis" is when young animals are similar to adults and change gradually into the adult form, and "complete metamorphosis" is when there is a profound change between larval and adult forms. Butterflies have complete metamorphosis, grasshoppers have incomplete metamorphosis.
having the capacity to move from one place to another.
the area in which the animal is naturally found, the region in which it is endemic.
active during the night
reproduction in which eggs are released by the female; development of offspring occurs outside the mother's body.
the business of buying and selling animals for people to keep in their homes as pets.
the kind of polygamy in which a female pairs with several males, each of which also pairs with several different females.
rainforests, both temperate and tropical, are dominated by trees often forming a closed canopy with little light reaching the ground. Epiphytes and climbing plants are also abundant. Precipitation is typically not limiting, but may be somewhat seasonal.
reproduction that includes combining the genetic contribution of two individuals, a male and a female
associates with others of its species; forms social groups.
a wetland area that may be permanently or intermittently covered in water, often dominated by woody vegetation.
Living on the ground.
