Goltz had raised the temperature of the water from 17.5 °C to 56 °C in about ten minutes, or 3.8 °C per minute, in his experiment, whereas Heinzmann heated the frogs over the course of 90 minutes from about 21 °C to 37.5 °C, a rate of less than 0.2 °C per minute. [2]
It is usually found close to water, but it can stay on dry land for long periods of time. [11] During warmer months, it moves away from the water for most of the time, [15] It is mostly nocturnal, [15] but it can be active during the day and the night, especially during rainfall. It breeds in the winter and spring, and sometimes in the fall.
Water-holding frogs are ectothermic, [8] meaning they depend on external sources of body heat. Aestivation is a behaviour characteristic of water holding frogs. It is similar to how other animals hibernate, except it takes place during summer as opposed to winter when weather conditions are hot and dry. This behaviour is a response to high ...

The mating period of these frogs is during the fall and winter seasons. These frogs call usually during the morning and mid-afternoon hours. [15] Males of this species do not attract females with croaks, instead producing a sharp clicking sound by snapping the hyoid bone in their throats. [16] The clicking sound resembles metallic noises.
Although these frogs can swallow animals almost half their size, they sometimes attempt to eat things larger than they are. Their teeth, as well as bony projections in the front of the jaw, can make it difficult for them to release prey after taking it in their mouth, in some cases leading to death by choking.

The common frog is a poikilotherm and is able to function over a wide range of body core temperatures.. A poikilotherm (/ ˈ p ɔɪ k ə l ə ˌ θ ɜːr m, p ɔɪ ˈ k ɪ l ə ˌ θ ɜːr m /) is an animal (Greek poikilos – 'various', 'spotted', and therme – 'heat') whose internal temperature varies considerably.
