Dolichotinae
Maras, subfamily Dolichotinae, are a group of rodents in the family Caviidae. These large relatives of guinea pigs are common in the Patagonian steppes of Argentina, but also live in Paraguay and elsewhere in South America. There are two extant species, the Patagonian mara of the genus '' Dolichotis'' and the Chacoan mara of the genus '' Pediolagus''; traditionally this species was also thought to belong to ''Dolichotis'' howeve,r a 2020 study by the American Society of Mammalogists found significant difference between the two mara species to warrant resurrecting the genus ''Pediolagus'' for it. Several extinct genera are also known. Description Maras have stocky bodies, three sharp-clawed digits on the hind feet, and four digits of the fore feet. Maras have been described as resembling long-legged rabbits. Patagonian maras can run at speeds up to . The Patagonian species can weigh over in adulthood. The average weight of adult male Patagonian maras is and in adult female ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caviidae
Caviidae, the cavy family, is composed of rodents native to South America and includes the domestic guinea pig, wild cavies, and the largest living rodent, the capybara. They are found across South America in open areas from moist savanna to thorn forests or scrub desert. This family of rodents has fewer members than most other rodent families, with 19 species in 6 genera in 3 subfamilies. Characteristics With the exception of the maras, which have a more rabbit-like appearance, caviids have short, heavy bodies and large heads. Most have no visible tails. They range in size from the smaller cavies at 22 cm in body length, and 300 grams in weight, up to the capybara, the largest of all rodents at 106 to 134 cm in length, and body weights of 35 to 66 kilograms. Even larger forms existed in the Pliocene, such as '' Phugatherium'', which was about the size of a tapir. They are herbivores, eating tough grasses or softer leaves, depending on species.

Chacoan Mara
The Chacoan mara (''Pediolagus salinicola'') or Chacoan cavy is a relatively large South American rodent of the cavy family. They are a close relative of the better known Patagonian mara. The Chacoan mara is the sole member of the genus ''Pediolagus''. Taxonomy Until recently ''Pediolagus'' was considered synonymous with '' Dolichotis'' and the Chacoan mara was a member of that genus. However, a 2020 study by the American Society of Mammalogists found significant difference between the two mara species to warrant resurrecting ''Pediolagus''. Habitat The Chacoan mara lives in the South American Chaco, the dry thorny forests and grasslands of Argentina, Paraguay, and Bolivia. Maras dig a burrow An Eastern chipmunk at the entrance of its burrow A burrow is a hole or tunnel excavated into the ground by an animal to construct a space suitable for habitation or temporary refuge, or as a byproduct of locomotion.

Dolichotis
''Dolichotis'' is a genus of the cavy family of rodents. These large relatives of guinea pigs are common in the Patagonian steppes of Argentina, but also live in Paraguay and elsewhere in South America. It contains a single extant species, the Patagonian mara, which is the one of the largest rodents in the world after the two species each of capybaras and beavers, and the large species of porcupines, reaching about in height. The Chacoan mara has and sometimes still is also considered a member of this genus. However, a 2020 study by the American Society of Mammalogists found significant difference between the two mara species to warrant placing it in the genus ''Pediolagus''. Etymology ''Dolichotis'' means "long-eared" (from "long" and "ear") in Ancient Greek. Species One extant and two extinct species of in this genus are recognized: ;Fossil species * †''D. intermedia'' * †''D. platycephala'' Fossils are known from Argenti ...

Archive
An archive is an accumulation of historical records or materials – in any medium – or the physical facility in which they are located. Archives contain primary source documents that have accumulated over the course of an individual or organization's lifetime, and are kept to show the function of that person or organization. Professional archivists and historians generally understand archives to be records that have been naturally and necessarily generated as a product of regular legal, commercial, administrative, or social activities. They have been metaphorically defined as "the secretions of an organism", and are distinguished from documents that have been consciously written or created to communicate a particular message to posterity. In general, archives consist of records that have been selected for permanent or long-term preservation on grounds of their enduring cultural, historical, or evidentiary value. Archival records are normally unpublished and almost al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropical Wings
The tropics are the regions of Earth surrounding the Equator. They are defined in latitude by the Tropic of Cancer in the Northern Hemisphere at N and the Tropic of Capricorn in the Southern Hemisphere at S. The tropics are also referred to as the tropical zone and the torrid zone (see geographical zone). In terms of climate, the tropics receive sunlight that is more direct than the rest of Earth and are generally hotter and wetter as they aren't affected as much by the solar seasons. The word "tropical" sometimes refers to this sort of climate in the zone rather than to the geographical zone itself. The tropical zone includes deserts and snow-capped mountains, which are not tropical in the climatic sense. The tropics are distinguished from the other climatic and biomatic regions of Earth, which are the middle latitudes and the polar regions on either side of the equatorial zone. The tropics constitute 40% of Earth's surface area and contain 36% of Earth's landmass. , th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Melbourne Zoo
Melbourne Zoo is a zoo in Melbourne, Australia. It is located within Royal Park in Parkville, approximately north of the centre of Melbourne. It is the primary zoo serving Melbourne.

Bicycles are not allowed inside the zoo itself. The Royal Melbourne Zoological Gardens is a full institutional member of the Zoo and Aquarium Association and the World Association of Zoos and Aquariums. The zoo is set among flower gardens and picnic areas. Many of the animals are now organised in bioclimatic zones: African rainforest ('Gorilla Rainforest') that include gorillas and lemurs; Asian rainforest ('Trail of the 'Elephants') that includes elephants, orangutans, tigers and otters; and the Australian bush with kangaroos, koalas, wo ...
