Chinchilla-Complete1
Chinchilla lanigera Chinchilla Class: Mammalia. Order: Rodentia. Family: Chinchillidae. Other names: Physical Description: A small mammal with extremely dense, velvet-like, blue-gray fur with black tinted markings. It has large, rounded ears, big eyes, a bushy tail, and long whiskers. The front paws have only four well-developed digits; the fifth toe is vestigial. The hind legs are longer than the forelimbs with three large toes and one tiny one. It is quite agile and capable of leaping both horizontally and vertically, reaching heights up to 6ft vertically. Weight is reported to range from18-35 oz. The head and body is 9-15”, averaging 12”; the tail averages 3-6”. Females (does) are larger and heavier than males (bucks). Crying, barking, chattering, chirping, and a crackling vocalization if angry are all normal sounds for a chinchilla. Domestic chinchillas have been selectively bred to rear other colors beside the wild blue-gray including beige, silver, cream and white. Diet in the Wild: Bark, grasses, herbs, seeds, flowers, leaves. Diet at the Zoo: Timothy hay, chinchilla diet, apples, grapes, raisins, banana chips, almonds, peanuts, sunflower seeds, romaine. Habitat & Range: High Andes of Bolivia, Chile, and Peru, but today colonies in the wild remain only in Chile, live within rocky crevices and caverns. Life Span: Up to 15-20 years in captivity; avg. 8-10 in the wild. Perils in the wild: Birds of prey, skunks, felines, snakes, canines, and humans. Physical Adaptations: If threatened, chinchillas depend upon their running, jumping, and climbing skills. If provoked, they are capable of inflicting a sharp bite. -
Chinchillas History the Chinchilla Is a Rodent Which Is Closely Related To
Chinchillas History The chinchilla is a rodent which is closely related to the guinea pig and porcupine. The pet chinchilla’s wild counterpart inhabits the Andes Mountain areas of Peru, Bolivia, Chile, and Argentina. In the wild state, they live at high altitudes in rocky, barren mountainous regions. They have been bred in captivity since 1923 primarily for their pelts. Some chinchillas that were fortunate enough to have substandard furs were sold as pets or research animals. Today chinchillas are raised for both pets and pelts. Chinchilla laniger is the main species bred today. They tend to be fairly clean, odorless, and friendly pets but usually are shy and easily frightened. They do not make very good pets for young children, since they tend to be high-strung and hyperactive (both children and chinchillas). The fur is extremely soft and beautiful bluish grey in color thus leading to their popularity in the pelt industry. Current color mutations include white, silver, beige, and black. Diet Commercial chinchilla pellets are available, but they are not available through all pet shops and feed stores. When the chinchilla variety is not in stock, a standard rabbit or guinea pig pellet can be fed in its place. Chinchillas tend to eat with their hands and often throw out a lot of pellets thus cause wastage. A pelleted formulation should constitute the majority of the animal’s diet. “Timothy”, or other grass hay, can be fed in addition to their pellets. Alfalfa hay is not recommended due to its high calcium content relative to phosphorus. Hay is a beneficial supplement to the diet for nutritional and psychological reasons. -

Association of Pet Behaviour Counsellors www.apbc.org.uk E: [email protected] Chinchilla Factsheet Introduction Chinchillas are South American rodents with soft, dense coats, large ears and eyes and a long hairy curled tail. They are becoming increasingly popular as pets in the UK and can commonly be found for sale in pet shops. This species has complex social, environmental and behavioural needs which need to be met if they are to be kept happily as pets. This information leaflet is about the history and natural behaviour of the chinchilla, and how to meet their behavioural needs as pets. If you already have chinchillas, this guide willhelp you understand your chinchillas so that you can provide for their needs, and if you are thinking about getting chinchillas it can help you to decide whether they are the right pet for you and your household. The Natural History chinchillas have descended from 12 feed on different plants when they of Wild Chinchillas wild chinchillas (C. lanigera) captured become available so their diet varies in 1923 by Mathias. F Chapman and greatly between the wet and dry Chinchillas belong to the family taken to the USA (Spotorno et al, seasons(Cortés, Miranda & Jiménez, Chinchillidae, which consists of 2004). Today, they are kept as fur- 2002). Their main food plants are chinchillas and viscachas (Marcon bearing animals, laboratory animals the bark and leaves of native herbs & Mongini, 1984). There are two and pets. and shrubs, and succulents such as species of chinchilla; Chinchilla bromeliads and cacti ( Cortés,Miranda lanigera, the long-tailed chinchilla, Habitat & Jiménez, 2002). -

Dwarf Hamster Care Sheet Because We Care !!!
Dwarf Hamster Care Sheet Because we care !!! 1250 Upper Front Street, Binghamton, NY 13901 607-723-2666 Congratulations on your new pet. Dwarf hamsters make good household pets as they are small, cute and easy to care for. Most commonly you will find Djungarian or Roborowski hamsters available. They are more social than Syrian (golden) hamsters and can often be kept in same sex pairs if introduced at a young age. Djungarian are brown or grey with a dark stripe down their back and furry feet. They grow to three to four inches in length and live up to two years. Roborowski hamsters are brown with white muzzle, eyebrows and underside. They grow to less than two inches long and live two to three years. GENERAL Give your new hamster time to adjust to its new home. Speak softly and move slowly so your hamster can learn to trust you. Put your hand in the cage and let the hamster smell you. In a short amount of time the hamster will recognize you and feel safe. Be sure to always wash your hands so you smell like you. Hamsters are naturally curios and can be encouraged to sit on your hand for a special treat. Cup your hands under and around the hamster so he feels safe, never squeeze or move suddenly and stay low to the floor so that if he jumps he won’t get injured. Dwarf hamsters tend to be less aggressive than standard hamsters and are frequently referred to as “no bite” hamsters. Keep in mind however that any animal will bite if frightened or injured. -
Comparative Analysis of the Karyotypes of the Greater Long-Tailed Hamster and the Chinese Hamster
C 1997 The Japan Mendel Society Cytologia 62: 315-321, 1997 Comparative Analysis of the Karyotypes of the Greater Long-Tailed Hamster and the Chinese Hamster Kazunori Fujimoto1, Sen-ichi Oda1,*, Kazuhiro Koyasu2, Masashi Harada3 and Shin-ichi Sonta4 1 Laboratory of Animal Management, School of Agricultural Sciences, Nagoya University, Nagoya 464-01, Japan 2Department of Anatomy , School of Dentistry, Aichi-Gakuin University, Nagoya 464, Japan 3 Laboratory Animal Center , Osaka City University, Osaka 545, Japan 4 Department of Genetics , Institute for Developmental Research, Aichi Human Service Center, Kasugai 480-03, Japan Accepted July 17, 1997 The subfamily Cricetinae (Rodentia) comprise 5 genera, including the genus Cricetulus of which comprise 11 species (Nowak and Paradiso 1983). The greater long-tailed hamster (Cricetulus trion or Tscherskia triton, abbreviated hereafter as a triton hamster) inhabits north-eastern Asia such as eastern Siberia, north-eastern China and Korea (Ellerman and Morrison-Scott 1951), and its diploid chromosome number is 28 (Tsuchiya and Won 1976). The Chinese hamster (Cricetulus griseus, 2n=22) has been successfully used as a laboratory animal, and its karyotype has been characterized by banding techniques (Ray and Mohandas 1976). In contrast, no cytogenetic analy- ses are available for a triton hamster. There are remarkable morphological differences between the two hamster species. The triton hamster is 5-6 times as weighty as Chinese hamster (Sonta and Semba 1980, Oda et al. 1995), and we are not able to obtain interspecific hybrid in cage. The coat color of the two hamster species also differs. That of the Chinese hamster is brown at back with black line in the center and white at belly, while that of a triton hamster is agouti at back. -
Chinchilla Chinchilla
Spencer Murray BES 485 – Winter 2014 South American Wildlands Biodiversity Research and Communication Project The Chinchilla chinchilla A description of the Chinchilla chinchilla The Chinchilla chinchilla, also called the short-tailed chinchilla, is one of two species of chinchilla, which was previously known as Chinchilla brevicaudata until 1977 (Woods and Kilpatrick 2005). The species C. chinchilla has also called the Bolivian, Peruvian, and Royal chinchilla (Jiménez, 1996). It is about the size of a rodent and has, on average, a body that is heavier and longer than the other species of chinchilla, Chinchilla lanigera, although C. lanigera has a longer tail, which is why it is known as the long-tailed chinchilla. The C. chinchilla is gray in color, with a body similar to a squirrel, and large ears like a mouse. They have extremely plush fur with over 50 hairs per single follicle, (humans have one hair per follicle; Meadow, 1969). C. chinchilla has also been described as being about the size of a small rabbit with long soft fur (Grau, 1986), and a species that has one of the softest, longest, and finest furs of any wild mammal (Sage 1913; Walker 1968; Mann, 1978). *Side view photo of C. chinchilla: www.chinformation.com* Ecology of the C. chinchilla and its role in the ecosystem There is not much known about the ecology of the wild chinchilla, but what is known is that they live in colonies that can range from a few individuals to several hundred of the species (Mohlis, 1983). The C. chinchilla is a colonial species that feeds on vegetation and lives in rocky burrows or crevices in arid climates (IUCN Redlist: http://www.iucnredlist.org/details/4651/0). -
Lessons from the Hamster
LESSONS FROM THE HAMSTER: CHARACTERIZATION OF CHINESE HAMSTER OVARY (CHO) CELL LINES AND CRICETULUS GRISEUS TISSUES VIA PROTEOMICS AND GLYCOPROTEOMICS by Kelley Marie Heffner A dissertation submitted to Johns Hopkins University in conformity with the requirements for the degree of Doctor of Philosophy Baltimore, Maryland August, 2017 © 2017 Kelley Marie Heffner All Rights Reserved Abstract Chinese hamster ovary (CHO) cells were isolated in the late 1950’s and have been the workhorse of biotherapeutics production for decades. While previous efforts compared CHO cell lines by proteomics, research into the original Chinese hamster (Cricetulus griseus) host has not been conducted. Thus, we sought to understand proteomic differences across CHO-S and CHO DG44 cell lines in relation to brain, heart, kidney, liver, lung, ovary, and spleen tissues. As glycosylation is critical for recombinant protein quality, we additionally performed a glycoproteomics and sialoproteomics analysis of wild-type and mutant CHO cell lines that differ in glycosylation capacity. First, wild-type CHO was compared with tunicamycin-treated CHO and Lec9.4a cells, a mutant CHO cell line which shows 50% of wild-type glycosylation levels. A total of 381 glycoproteins were identified, including heavily-glycosylated membrane proteins and transporters. Proteins related to glycosylation downregulated in Lec9.4a include alpha-(1,3)-fucosyltransferase and dolichyl- diphosphooligosaccharide-protein glycosyltransferase subunit 1. Next, wild-type Pro-5 CHO was compared with Lec2 cells, which have a mutation in CMP-sialic acid transporter that reduces sialylation. A total of 272 sialylated proteins were identified. Downregulated sialoproteins, including dolichyl- diphosphooligosaccharide-protein glycosyltransferase subunit STT3A and beta-1,4- galactosyltransferase 3, detect glycosylation defects. -
