Płazy beznogie (Gymnophiona) stanowią jeden z trzech rzędów współcześnie żyjących płazów. Występują głównie w tropikalnych regionach Azji, Afryki oraz Ameryki Środkowej i Południowej. Większośćz nich prowadzi podziemny tryb życia, a ich pozbawione kończyn, podzielone na pierścienie wydłużone ciało, przypomina dżdżownicę. Liczne adaptacje płazów beznogich do podziemnego trybu życia są coraz częściej przedmiotem badań. Wiedza na temat ich pochodzenia i taksonomii jest fragmentaryczna. W dodatku, dotychczas odnaleziony i opisany zapis kopalny jest bardzo skąpy. Pomimo licznych badań, wciąż niewiele wiadomo również na temat ekologii Gymnophiona. Dotychczas ustalono między innymi że niemal połowa spośród znanych 188 gatunków jest żyworodna. Większość aktualnych badań dotyczy określenia pokrewieństwa pomiędzy poszczególnymi rodzinami oraz szerszego poznania biologii ich rozrodu. Celem tej pracy jest zaprezentowanie wiedzy z zakresu pochodzenia, środowiska życia, anatomii, odżywiania oraz rozrodu Gymnophiona.

Caecilians (Gymnophiona) are one of the three modern order of amphibians. They live in tropical regions of the Old World and the New World and in most their lifestyle is underground. Additionally, their limbless, divided into annuli, elongate body, externally resembles earth-worm. Numerous adaptations of Gymnophiona to underground life arouse interest. The knowledge of their origin and taxonomy is incomplete. So far, the fossil record which has been found and described is very scanty. Despite abundant research, the knowledge about ecology of these animals is still deficient. Most of modern research focuses currently on establishing relationships among the families and their breeding. The aim of the paper is to present the latest research on the biology of the caecilinas (origin, environment, anatomy, nutrition and breeding).
