Wood frogs in natural hibernation remain frozen for 193 +/- 11 consecutive days and reached an average (October–May) temperature of −6.3 °C (20.7 °F) and an average minimum temperature of −14.6 ± 2.8 °C (5.7 ± 5.0 °F). The wood frog has evolved various physiological adaptations that allow it to tolerate the freezing of 65–70% of ...
Stones swallowed by ostriches can exceed a length of 10 centimetres (3.9 in) [citation needed]. Apparent microgastroliths have also been found in frog tadpoles. [ 2 ] Ingestion of silt and gravel by tadpoles of various anuran (frog) species has been observed to improve buoyancy control.
[3] [9] [23] The diet of Cope's gray treefrog primarily consists of insects such as moths, mites, spiders, plant lice, and harvestmen. Snails have also been observed as a food source. Like most frogs, Dryophytes chrysocelis is an opportunistic feeder and may also eat smaller frogs, including other treefrogs. [24]
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.
