The Gray Treefrog, Dryophytes versicolor, is a small, adaptable amphibian native to much of the eastern United States and parts of Canada. This species is renowned for its remarkable ability to change color from gray to green, depending on its environment and activity, aiding in camouflage among trees and foliage. Adult Gray Treefrogs typically measure between 3.2 to 5.1 centimeters (1.25 to 2 inches) in length, with females generally larger than males. They possess a slightly rough skin texture and are characterized by their bright yellow or orange inner thighs, a feature visible when they jump.

| Population: | Widespread and common, not currently considered threatened |
| Generation Length: | 2-3 years |
| Average Weight: | Usually not measured due to small size, but typically 5-11 grams |
| Average Length: | 3-5 cm |
| Lifespan: | Up to 7-9 years in the wild, potentially longer in captivity |
| Diet: | Insectivorous, consuming a wide variety of small invertebrates |
| Conservation Status: | Least Concern (LC) |
Gray Treefrogs inhabit a wide range of forested environments, particularly those near ponds, lakes, or marshes, which are crucial for their breeding. They are arboreal, spending much of their time in trees, and are known for their strong adhesive toe pads that allow them to climb and cling to vertical surfaces easily. These frogs are nocturnal, becoming most active at night when they feed on a variety of insects and other small invertebrates.
The diet of the Gray Treefrog consists mainly of insects such as moths, flies, and beetles, which they catch with their sticky tongues. This insectivorous diet plays a significant role in controlling pest populations in their habitats.
Reproduction for Gray Treefrogs occurs in the spring and early summer when males call to attract females to breeding sites in standing water. Females lay hundreds of eggs in small clusters attached to vegetation in the water. The eggs hatch into tadpoles, which undergo metamorphosis into froglets within a few months, completing their transition to terrestrial life.
The Gray Treefrog is currently considered to be of Least Concern by the IUCN, reflecting its wide distribution and presumed large population. However, like many amphibian species, they face threats from habitat loss, pollution, and climate change, which could impact their breeding sites and overall survival. Conservation efforts for Gray Treefrogs include protecting wetland habitats, monitoring populations, and reducing pesticide use to ensure the continued health and diversity of this and other amphibian species in their ecosystems.

Gray treefrogs can change their skin color to blend with their surroundings, ranging from gray to green.
This ability helps them avoid predators and regulate their body temperature. The color change is influenced by temperature, humidity, and the frog's mood. These frogs are commonly found in the eastern United States and are noted for their musical trills during mating season.



The Northern Crested Newt, triturus cristatus, is a striking amphibian known for its impressive size and distinctive appearance among European newts. Adult males can reach lengths of up to 18 cm, making them one of the largest newt species in their range. During the breeding season, males display a dramatic,

The Natterjack Toad, epidalea calamita, is a distinctive amphibian species known for the yellow line running down the middle of its back. Smaller than the common toad, adults typically measure about 6 to 7 cm in length. Their skin is warty and varies in color from greenish to brownish, providing

The Strawberry Poison-Dart Frog, oophaga pumilio, is a small yet vibrantly colored amphibian native to Central America, specifically found in humid lowlands from Nicaragua to Panama. This species is renowned for its striking appearance, typically bright red or blue with black markings, although coloration can vary significantly across different populations,

The Ornate Chorus Frog, pseudacris ornata, is a small, vibrantly patterned amphibian native to the southeastern United States. This species is known for its striking appearance, featuring a background color that can range from green to brown, overlaid with darker markings that often form a bold, net-like pattern. Adult Ornate
