California tree frog

The California tree frog or California chorus frog (Pseudacris cadaverina) is a "true" tree frog (family Hylidae) from southern California (USA) and Baja California (Mexico).[2] Until recently, the California tree frog was classified in the genus Hyla.[2][3]

Description

It is a cryptically colored species of tree frog, often resembling granitic stones. It is grey or light brown on its dorsum with darker blotches, and has a whitish venter. It is yellow on the undersides of its legs, groin, and lower abdomen; males of the species have a dusky-yellow throat. The California tree frog has conspicuous toe webbing and pads, and its dorsal skin is roughened and warty. It is 2.9–5 cm (1.1–2.0 in) long.[3][4]

Habitat and conservation

This species is most likely to occur along streams with abundant boulders and cobbles in their channels. Its distribution is spotty and localized. These frogs are easily handled.[4]

California tree frog is not considered threatened by IUCN: it is a relatively common species with broad distribution, and there are no major threats, except perhaps UV radiation that reduces embryonic survival.[1]

gollark: I don't think you can *in general*, but you'll probably know in some cases what the content might be. Lots of network protocols and such include checksums and headers and defined formats, which can be validated, and English text could be detected.
gollark: But having access to several orders of magnitude of computing power than exists on Earth, and quantum computers (which can break the hard problems involved in all widely used asymmetric stuff) would.
gollark: Like how in theory on arbitrarily big numbers the fastest way to do multiplication is with some insane thing involving lots of Fourier transforms, but on averagely sized numbers it isn't very helpful.
gollark: It's entirely possible that the P = NP thing could be entirely irrelevant to breaking encryption, actually, as it might not provide a faster/more computationally efficient algorithm for key sizes which are in use.
gollark: Well, that would be inconvenient.
