This list includes 17 Amphibians that start with G, from “Giant African bullfrog” to “Gulf Coast toad”. They range from large burrowing frogs to small coastal toads, occupying tropical and temperate habitats worldwide. Use this list as an educational reference, a quick field guide, or a classroom resource.

Amphibians that start with G are frogs, toads, salamanders, and newts with common names beginning with G. A notable example is the Giant African bullfrog, known for its large size and widespread recognition.

Below you’ll find the table with Common name, Scientific name, Habitat, Lifespan

Common name: The everyday name you see in field guides; it helps you quickly identify species in the field or literature.

Scientific name: The formal Latin binomial gives exact species identity and lets you match names across guides and databases worldwide.

Habitat: A short habitat note shows where the species lives, so you can understand its ecological needs and likely locations.

Lifespan: Typical lifespan ranges give you expected years in the wild or captivity, useful for care, study, or conservation planning.

Descriptions

Goliath frog
World’s largest frog (up to 30+ cm); heavy-bodied, powerful jumper, threatened by hunting and habitat loss.
Giant African bullfrog
Large, robust frog to ~24 cm; males guard tadpoles and it estivates in dry seasons; locally harvested for food.
Golden poison frog
Small (3–4 cm), brilliantly colored and extremely toxic in the wild; notable for potent skin alkaloids and conservation concerns.
Golden mantella
Tiny, vivid orange-yellow frog (~2–3 cm); toxic alkaloids, critically endangered from habitat loss and collection.
Green tree frog
Plump, docile frog up to ~10 cm; bright green skin, popular pet species with loud calls.
Green frog
Medium-sized pond frog (6–9 cm) common in wetlands; males have a distinctive “gunk” call.
Gray treefrog
Small arboreal frog (3–5 cm) that changes color for camouflage; excellent jumper and cold-tolerant.
Green and golden bell frog
Attractive green-and-gold patterned frog (6–10 cm); populations declined from habitat loss and disease.
Green toad
Robust toad (4–9 cm) often with green speckling; tolerates arid and urban habitats.
Gopher frog
Stocky frog that uses gopher tortoise burrows; seasonal breeder with blotched pattern.
Gulf Coast toad
Medium-sized, warty toad common near coasts and human areas; adaptable and widespread.
Greater siren
Eel-like salamander up to ~1 m, retains external gills as an adult; fully aquatic and nocturnal.
Green-and-black poison dart frog
Small (2–4 cm), brightly patterned frog used in DART frog exhibits; less toxic than some relatives.
Giant tree frog
Large arboreal frog (8–14 cm) with strong limbs; excellent climber and sometimes kept as a pet.
Greenhouse frog
Tiny (2–3 cm) terrestrial frog often around homes; lays direct-developing eggs (no tadpole stage).
Grass frog
Common European frog (6–9 cm) with variable brown-green tones; breeds in early spring ponds.
Guenther’s frog
Medium stream-dwelling frog (4–7 cm) named for zoologist Günther; agile jumper in forested habitats.
