Phrynomancy

A toad in the early evening, likely engaged in some manner of phrynomancy. (CC-4.0)

Phyrnomancy (from the Greek: phrynos, toad + manteía, prophecy) is a form of divination whereby the movements of a toad are adjudged by the diviner to have certain meaning in the forecasting of future events, often in relation to objects the toad interacts with, whether placed intentionally or not.

The term and practice may be considered as interchangeable with batraquomancy (from the Greek: batrakhos, frog + manteía, prophecy), divination using frogs generally, as well as other amphibians, including newts.
