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.

- age at first birth
- Age at which females give birth to their first litter, or their young attach to teats or hatch out
- A linear shoaling landform feature within a body of water. Bars tend to be long and narrow (linear) and develop where a current (or waves) promote deposition of granular material, resulting in localized shallowing (shoaling) of the water. Bars can appear in the sea, in a lake, or in a river. They are typically composed of sand, although could be of any granular matter that the moving water has access to and is capable of shifting around (for example, soil, silt, gravel, cobble, shingle, or even boulders). The grain size of the material comprising a bar is related: to the size of the waves or the strength of the currents moving the material, but the availability of material to be worked by waves and currents is also important.
- 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.
- Naturally formed, subterranean open area or chamber.
- 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 plane angle unit which is equal to 1/360 of a full rotation or 1.7453310^[-2] rad.
- 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.
- forelimb length
- The distance from point to point along the longest axis of the anterior/superior jointed appendages used for locomotion or grasping.
- gestation period duration
- The length of time between when a fertilized egg implants in the wall of the uterus and the birth of offspring.
- A category or description of the habitat in which the Event occurred.
- inter-birth interval
- The length of time between successive births of a female.
- 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.
- The geographic latitude (in decimal degrees, using the spatial reference system given in geodeticDatum) of the geographic center of a Location. Positive values are north of the Equator, negative values are south of it. Legal values lie between -90 and 90, inclusive.
- litters per year
- Number of litters per female per year
- The geographic longitude (in decimal degrees, using the spatial reference system given in geodeticDatum) of the geographic center of a Location. Positive values are east of the Greenwich Meridian, negative values are west of it. Legal values lie between -180 and 180, inclusive.
- million years ago
- 1 megaannum in the past. Megaannum, Ma. is a unit of time equal to one million (10^6) years.
- onset of fertility
- The age at which an organism develops the ability to produce live offspring.
- 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.
- 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.
For some attributes EOL determines the span of values available for a taxon across all sources.
