Word Origin & History. moniker 1849, said to be originally a hobo term (but attested in London underclass from 1851), of uncertain origin; perhaps from monk (monks and nuns take new names with their vows, and early 19c. British tramps referred to themselves as in the monkery).
northern American bull frog (female) Frogs, toads, and salamanders belong to a class of animals called Amphibians. They are vertebrates (back-boned animals) with smooth (moist) or warty skins. They lay unshelled eggs, usually in water, and most species have a gilled, swimming larval stage (such as a tadpole).
These salamanders eat a wide variety of prey, including spiders, worms, dragonflies, slugs, centipedes, insect eggs, frog eggs and other small invertebrates. Salamanders that live in the water have gills like a fish and are quick, agile swimmers. A few of them have special bones that allow them to shoot out their tongues like cannons, but most aquatic species hunt by out-swimming their targets and catching them in their wide mouths.
