Tiny amphibians are a group of small animals that live both on land and in water. The two most common types of tiny amphibians are efts (4 letters) and NEWTS (5 letters). Efts are small, terrestrial salamanders found in North America, while NEWTS are aquatic salamanders found in Europe, Asia, and North America. Both efts and NEWTS have slimy skin and can grow up to 4 inches in length. They are both carnivorous and feed on insects, worms, and other small invertebrates.
