The underground environment poses particular communication challenges for subterranean rodents. Some loud and low-pitched acoustic signals that can travel long distances are appropriate for long-range underground communication ...

Tuco-tucos (Ctenomys spp.) are subterranean rodents that produce territorial, high intensity long-range vocalizations (LRVs) of broadband and low frequency that are essential for long-distance communication between individuals ...

Amerotyphlops. costaricensis is difficult to observe in the field and is considered a rare species. There are fewer than ten individuals deposited in museum collections, representing roughly one population in both Nicaragua ...

A new species of ghost shrimp, Callichirus santensis sp. nov., is described from the Upper Pleistocene Cananéia Formation, southeast Brazil. The new species is described based upon preserved ischium, carpus, propodus, and ...

We studied the foot musculature of the fossorial family Odontophrynidae (composed of the genera Macrogenioglottus, Odontophrynus, and Proceratophrys) plus several outgroup taxa from Hyloidea and other burrowing taxa from ...
