Não, anfíbios não têm escamas:
Anfíbios são animais vertebrados de pele fina e úmida, sem pelos ou escamas.
A pele úmida dos anfíbios é permeável a água e gases, e é auxiliada por glândulas que produzem muco para mantê-la úmida.
A pele úmida dos anfíbios é importante para a respiração, pois auxilia na captação de oxigênio, tanto na terra quanto na água.
Os anfíbios são conhecidos por ter uma "vida dupla", pois possuem uma fase de vida aquática e outra terrestre. Alguns exemplos de anfíbios são:
Sapos, Rãs, Pererecas, Salamandras, Tritões, Cobras-cegas ou cecílias.

Amphibians are devoid of scales because they are descendants of fish, which also lack scales. Early amphibians evolved from lobe-finned fish, which had bony plates in their skin instead of scales. Over time, these bony plates transformed into the smooth, moist skin characteristic of modern amphibians. This adaptation allowed for better gas exchange through the skin, crucial for their semi-aquatic lifestyle.
