Contents
Chaltenobatrachus grandisonae (common name: Puerto Eden frog) is endemic to Patagonia, including both Chile and Argentina. It inhabits rain forests and wetlands of the southern fjordlands and Andes in Patagonia. It is known from just few localities: its type locality, Puerto Eden, Wellington Island, Chile, and two mainland sites in Argentina.
Description
Chaltenobatrachus grandisonae are small to medium-sized frogs, with adults reaching a snout–vent length of about 46 mm (1.8 in), with typical frog-like appearance and body proportions. Back of the body and limbs are rather uniformly bright green with brown to reddish warts. Tadpoles are up to 56 mm (2.2 in) in total length.
Reproduction
Chaltenobatrachus grandisonae lay their eggs in clusters attached to branches or stones under the water in still water, mostly temporary ponds. Each cluster has a few tens of eggs. Eggs are deposited in October (middle austral spring), and development to metamorphosis takes about 10–12 weeks, to December (early summer). In colder sites, development seems to take longer and tadpoles might overwinter.
