    Acanthochelys pallidipectoris (Freiberg 1945) – Chaco Side-Necked Turtle
    (2011) Thomas Vinke; Sabine Vinke; Enrique Richard; Mario R. Cabrera; Lorena Paszko; Pablo Marano; Sébastien Métrailler
    The Chaco Side-necked Turtle, Acanthochelys pallidipectoris (Family Chelidae), is a small to medium-sized freshwater turtle (carapace length to ca. 180 mm), endemic to the Chaco ecoregion of Argentina, Bolivia, and Paraguay. Its distribution is restricted to the temporarily flooded marshes and lowlands of dry shrub forest with impenetrable soils. The only record outside of the dry Chaco, in Mendoza, Argentina, is likely of anthropogenic origin. The activity period is very short (4-6 months a year), and populations consist of few animals. The species is threatened by habitat loss combined with climatic change leading to increased aridity and diminished ephemeral water resources. The species is currently categorized as Vulnerable on the IUCN Red List based on a 1996 evaluation, but has recently been provisionally re-assessed as Endangered. disTribuTion. -Argentina, Bolivia, Paraguay. Endemic to the Chaco ecoregion of southern Bolivia, western Paraguay, and northern Argentina.
