About Data on EOL
TraitBank gathers data and metadata from multiple sources into a single, fully-referenced and semantically accessible taxon-centric view.
Contact us for more information on sharing data sets with EOL or to recommend a data set for inclusion into TraitBank.
Funding for the development of EOL computable data functionality provided by the Alfred P. Sloan Foundation, the John D. and Catherine T. MacArthur Foundation, and from EOL users around the world. Contact the EOL Secretariat for more information on TraitBank.

Glossary for Chinchillidae
- age at first birth
- Age at which females give birth to their first litter, or their young attach to teats or hatch out
- body length (VT)
- The distance from point to point along the longest axis of the body of an organism.
- body mass
- The amount of matter in the body of an organism.
- A piece of rock with a grain size above 300 millimetres in diameter. Smaller boulders are, at times, referred to as rocks or stones.
- clutch/brood/litter size
- Single birth offspring quantity. The proportion or number of offspring produced from a single pregnancy (mammals) or ovulation (fish) or nesting (birds).
- A deep fissure in snow or ice.
- A region rendered barren or partially barren by environmental extremes, especially by low rainfall.
- dispersal age
- Age at which young permanently leave the parent, parental group, social group or any associated territories.
- This taxon is still in existence, as opposed to extinct.
- extinction status
- Indicates whether a taxon is extant (living today) or extinct.
- first appearance (older bound)
- The older bound for the first appearance of this taxon in the fossil record, in Ma.
- first appearance (younger bound)
- The younger bound for the first appearance of this taxon in the fossil record, in Ma.
- gestation period duration
- The length of time between when a fertilized egg implants in the wall of the uterus and the birth of offspring.
- An area in which grasses (Graminae) are a significant component of the vegetation.
- A category or description of the habitat in which the Event occurred.
- Descended but ascrotal testes, a derived condition in mammals.
- last appearance (older bound)
- The older bound for the last appearance of this taxon in the fossil record, in Ma.
- last appearance (younger bound)
- The younger bound for the last appearance of this taxon in the fossil record, in Ma.
- litters per year
- Number of litters per female per year
- million years ago
- 1 megaannum in the past. Megaannum, Ma. is a unit of time equal to one million (10^6) years.
- A landform that extends above the surrounding terrain in a limited area. A mountain is generally steeper than a hill, but there is no universally accepted standard definition for the height of a mountain or a hill although a mountain usually has an identifiable summit and a local relief of more than 300m.
- This statement is false; the answer to this question is no.
- This organism is not adapted for running.

- onset of fertility
- The age at which an organism develops the ability to produce live offspring.
- A region of general uniform slope, comparatively level, and of considerable extent.
- An elevated and comparatively level expanse of land.
- An area of land of low topographic relief that historically supported grasses and herbs, with few trees, and having generally a mesic (moderate or temperate) climate. Dominated by tall grasses (contrast steppe).
- records in BOLD?
- this clade is represented by geo-referenced data in the Barcode of Life Database (BOLD)
- records in GBIF?
- this clade is represented by geo-referenced data in the Global Biodiversity Information Facility (GBIF)
- references in BHL?

- sequences in GenBank?
- this clade is represented by gene sequences in GenBank
- social group size
- Number of individuals in a group that spends the majority of their time in a 24 hour cycle together where there is some indication that these individuals form a social cohesive unit.
- specimens in GGBN?
- this clade is represented by specimens in the Global Genome Biodiversity Network (GGBN)
- A plain without trees (apart from those near rivers and lakes); it is similar to a prairie, although a prairie is generally considered as being dominated by tall grasses, while short grasses are said to be normal in the steppe. It may be semi-desert, or covered with grass or shrubs or both, depending on the season and latitude.
- testis location
- Anatomical location of testis; eg: internal, descended, scrotal, inguinal.
- total life span
- The full period of time from birth to death of an organism.
- weaning age
- Age when primary nutritional dependency on the mother ends and independent foraging begins to make a major contribution to the offspring’s energy requirements.
- A physical quality inhering in a bearer that has mass near a gravitational body.
- Land having a cover of trees, shrubs, or both.
- This statement is true; the answer to this question is yes.
