These are tree frogs. 

These frogs live in leafy forests. 

Agalychnis is a group of tree frogs. 

These frogs have thin bodies and long legs. Their skin can be smooth. It can also be a bit bumpy. They have large eyes that stick out. To climb, they use webbed toes. They also have sticky pads on their toes. 
Many frogs in this group are green. Some can even change color. The lemur leaf frog is one example. It is green during the day. It turns orange or brown at night. Their bellies can be white, yellow, or orange.
These frogs use the thick leaves for safety. They hide from animals that might eat them. They also go to ponds to lay eggs. Most stay in the trees, but they go down to the water to breed. There are 14 different species in this group.
Agalychnis is a group of tree frogs. 

These frogs have a special way of moving through the trees. They have long and slender limbs. Their bodies are also quite flat. To climb, they use webbed toes. They also have adhesive pads on the tips of their digits. These pads help them stick to surfaces. 
Scientists have studied these frogs for a long time. In the past, they were called Pachymedusa. Now, we know they are closely related to the genus Phyllomedusa. Many different people have named the species in this group. For example, Cope named the red-eyed tree frog in 1862. Boulenger named the lemur leaf frog in 1882. Other researchers like Duellman and Ruiz-Carranza have found more species too.
There are 14 known species in the Agalychnis genus. 

You might recognize these frogs from stories about tropical jungles. They are part of a big world of living things. Most stay in the trees to find food and shelter. However, they must go down to ponds to breed. They gather around the water to lay their eggs. This cycle helps new frogs grow in the forest. It is a very busy way of life. 
Agalychnis is a genus of tree frogs found in the Neotropical region. This group includes 14 different species within the family Phyllomedusidae. These amphibians are vital members of the forest ecosystems they inhabit. They are primarily found in the dense forests of Mexico, Central America, and northwestern South America. 
These frogs are built specifically for life high above the ground. They possess slender bodies and long, thin limbs that allow for agile movement. Their bodies are often flattened, which helps them navigate through tight spaces in the vegetation. To move between branches, they use webbed toes and special adhesive pads located at the tips of their digits. These pads act like small suction cups to help them grip smooth surfaces. 
Coloration in the Agalychnis genus is highly varied and serves many purposes. Most species have dorsal coloration, which is the color on their backs, ranging from light green to dark green. Their ventral colors, or the colors on their undersides, can be white, yellow, or orange. Some species even exhibit the ability to change color based on the time of day. For example, the lemur leaf frog, Agalychnis lemur, is green during the daylight hours. At night, it transitions to a reddish-brown or orange-tan color. 
The habitat of these frogs is closely tied to the structure of the tropical forest. They primarily live in the forest canopy, which is the upper layer of the trees. This dense vegetation provides essential protection from predators and maintains the moisture they need. While they spend most of their lives in the trees, they must descend for reproductive purposes. During breeding periods, these frogs gather around ponds to deposit their eggs. 
Taxonomy, the science of naming and classifying living things, has changed for this genus over time. Scientists previously classified these frogs under the name Pachymedusa. Current research now shows that Agalychnis is closely related to the genus Phyllomedusa. Many researchers have contributed to our understanding of these species through different eras. Edward Drinker Cope described the red-eyed tree frog in 1862. Later, George Albert Boulenger named the lemur leaf frog in 1882. Other scientists, such as Duellman, Ruiz-Carranza, and Funkhouser, have identified many of the other species through the 20th century.
The 14 species in this genus vary significantly in size and location. Their body lengths typically span from 30mm to 88mm. For instance, the blue-sided leaf frog, Agalychnis annae, is found in Costa Rica and Panama. 

Understanding Agalychnis helps scientists learn more about the biodiversity of the Neotropical region. Because they rely on specific forest layers and water sources, they are closely linked to the health of the entire ecosystem. Their presence in the canopy and their seasonal trips to ponds connect the high trees to the forest floor. Studying their different colors, sizes, and habitats provides a window into how amphibians adapt to the complex world of tropical rainforests.
