This list includes 7 Amphibians that start with J, from “Japanese brown frog” to “Johnstone’s whistling frog”. These mostly frog and toad species span forest, stream and coastal habitats and support education, identification, and conservation efforts.

Amphibians that start with J are amphibian species whose common names begin with the letter J. Several, like the Japanese brown frog, figure prominently in local folklore and cultural imagery.

Below you’ll find the table with Common name, Scientific name, Habitat & range, Lifespan (years), and Notes.

Common name: The everyday name you will recognize and use when identifying species in field guides, reports, or casual observation.

Scientific name: The accepted binomial helps you confirm precise species identity and look up authoritative information and taxonomy.

Habitat & range: Short description of where the species lives and its geographic distribution to guide field searches and context.

Lifespan (years): Typical wild and, when available, captive age ranges in years to help with life-history comparisons.

Notes: Brief records on behavior, conservation status, or identifying features that give useful context for each entry.

Descriptions

Japanese giant salamander
Andrias japonicus is a giant, nocturnal salamander up to 1.5 m; a living relic facing habitat loss and conservation concern.
Japanese fire-bellied newt
Cynops pyrrhogaster is a small newt with a bright red belly used as a warning; common but locally declining from habitat change.
Japanese tree frog
Dryophytes japonicus is a small green tree frog often near homes; loud spring calls and adaptable to disturbed habitats.
Japanese brown frog
Rana japonica is a medium-sized frog common in rice paddies; active in spring breeding season and affected by land-use shifts.
Japanese wrinkled frog
Glandirana rugosa is a stocky, rough-skinned frog found by streams; tolerant locally but sensitive to pollution and habitat loss.
Javan wart frog
Limnonectes javensis is a robust, ground-dwelling frog endemic to Java; often near streams and threatened by deforestation.
Johnstone’s whistling frog
Eleutherodactylus johnstonei is a tiny frog named for its clear, whistling call; widespread in the Caribbean and often synanthropic.
