Where can you find more information about frogs?
OMG I’m so glad you asked! Here’s a quick 101 on frogs and their relatives, the amphibians.
Amphibians are ectotherms with moist, permeable skin.
Adults are independent of water, but most larvae are not.
Linnaeus defined class Amphibia (“dual life”) in 1758 as all vertebrates except mammals, birds, and bony fish
Eventually amphibians and reptiles were separated, but “herpetology” (the study of creeping things) persists. “Herpes” has the same root - “a creeping cutaneous eruption”
There are three orders of amphibians: salamanders, frogs, and caecilians
Salamanders
Four limbs (sometimes reduced)
Well-developed tails
Costal grooves (except Salamandridae)
824 species in 2025; 521 species in 2004 (~14 new species/year)
Primarily distributed in the northern continents with secondary invasion of the Neotropics
Centers of diversity in eastern U.S. and Neotropics (no salamanders in Australia or most of Africa)
Frogs
Four robust limbs on a compact body
Greatly elongated hind limbs and feet
No tail in adults
Caudal vertebrae fused into a rod (urostyle)
7842 species in 2025; 4904 species in 2004 (~140 new species/year)
Worldwide distribution
Center of diversity in the tropics
Caecilians
Limbless (not even girdles!)
Elongate, annulated bodies
Generally fossorial (burrowing)
Reduced eyes that are covered with skin and sometimes bone
Crazy fused skulls
231 species in 2025; 165 species in 2004 (~3 new species/year)
Circum-tropical distribution
Expert-curated websites
These have general information, images, range maps, and calls for many species. Better than wikipedia!
