European Fire-bellied Toad

The red-eyed tree frog is a vibrant, iconic inhabitant of Central and South American rainforests. With its bright green body, blue-and-yellow striped flanks, orange webbed feet, and striking, blood-red eyes, it is a master of color. During the day, it tucks its legs close and closes its eyes to blend in with green leaves. If disturbed, it flashes its bright colors and bulging red eyes to startle predators, a defense mechanism known as 'startle coloration'.

The Poison Dart Frog is a group of small, brightly colored amphibians native to the tropical rainforests of Central and South America. They are famous for their extremely toxic skin secretions, which indigenous tribes have used for centuries to poison the tips of blowdarts. Their brilliant, vibrant coloration serves as an warning sign to warn predators of their toxicity. Despite their name, captive-bred poison dart frogs are entirely harmless as their toxicity is derived from their wild diet.

The axolotl, also known as the Mexican walking fish, is a unique salamander famous for its smiling appearance and remarkable regenerative abilities. Unlike most amphibians, axolotls exhibit 'neoteny', meaning they never undergo metamorphosis to become land-dwelling adults. Instead, they remain aquatic, keeping their larval features—like feathery external gills and a tail fin—throughout their entire lives. They are highly studied by scientists because they can regenerate entire limbs, spinal cords, and even parts of their hearts and brains without scarring.
