Capybara
The capybara ("Hydrochoerus hydrochaeris") is a mammal native to South America. It is the largest living rodent in the world. Also called chigüire, chigüiro (in Colombia and Venezuela) and carpincho, it is a member of the genus "Hydrochoerus", of which the only other extant member is the lesser capybara ("Hydrochoerus isthmius"). Its close relatives include guinea pigs and rock cavies, and it is more distantly related to the agouti, the chinchilla, and the coypu. The capybara inhabits savannas and dense forests and lives near bodies of water. It is a highly social species and can be found in groups as large as 100 individuals, but usually lives in groups of 10–20 individuals. The capybara is not a threatened species but it is hunted for its meat and hide and also for grease from its thick fatty skin, which is used in the pharmaceutical trade.
Handbook of the Mammals of the World
Initially it was intended to publish only one volume on lagomorphs and rodents. But due to the large number of described rodents Lynx Edicions organized a survey from summer to autumn 2015 in which a majority of customers decided in favor of two volumes. The sixth volume is devoted to the lagomorphs and 25 families of rodents, including the hares, pikas, chinchillas, the Laotian rock rat (a living fossil), the capybara (the largest extant rodent), and the diverse group of squirrels. The 60 colour plates are created by Toni Llobet. It covers the details to the taxonomy, range, habitat, reproduction, behaviour, and conservation status of 798 species from 27 families in two orders. It includes a special chapter on the overview of rodents, on morphology, taxonomy, and evolutionary history; why rodents are studied; and tools for studying them. Edited by Don E. Wilson, Thomas E.
