Alsodes gargola, with the common name Tonchek spiny-chest frog, is a species of frog in the family Alsodidae. It is endemic to Argentina, where it occurs in northern Patagonia. This species is a semi-aquatic frog living around alpine lakes and streams. It overwinters for 8 months of the year and the tadpoles overwinter beneath the ice and snow. The species is threatened by exotic trout, but the populations are probably not yet in decline. Alsodes gargola adults and tadpoles have the ability to tolerate and adapt to low conductivity water and extreme overwintering conditions indicating that it could have the highest tolerance to overwintering compared to other frogs.
