Spotted paddle-tail newt
"Pachytriton" species are stout-bodied, smooth-skinned aquatic newts. Their heads are large and flattened, and they have conspicuous labial folds and short, stubby legs and toes. They breathe through both lungs and skin. 
"P. brevipes" ranges from 5.5 to 7.5 in as an adult. It has prominent labial folds, long digits, and smooth skin, which differs from the tuberculate skin typical of newts.
Moloch
In Karel Čapek's "War with the Newts" (1936), the Newts counter Christian attempts at conversion by turning to a god of their own creation named Moloch:
At a later period and almost universally the Newts themselves came to accept a different faith, whose origin among them is unknown; this involved adoration of Moloch, whom they visualized as a giant Newt with a human head; they were reported to have enormous submarine idols made of cast iron, manufactured to their orders by Armstrong or Krupp, but no further details ever leaked out of their cultic rituals since they were conducted under water; they were, however, believed to be exceptionally cruel and secret. It would seem that this faith gained ground rapidly because the name Moloch reminded them of the zoological "molche" or the German "Molch," the terms for Newt.
