At Animal Age, we source our data from the AnAge Database (Animal Ageing and Longevity Database), which is maintained by the Human Ageing Genomic Resources (HAGR). This database is recognized as one of the most comprehensive resources for animal longevity and aging-related data.
About Our Data Source
The AnAge Database provides high-quality curated data on aging and life history in animals, including maximum longevity, body size, growth rates, and reproductive parameters. This database is widely used in scientific research and is regularly cited in academic publications.
What We Track
For each animal species, we present the following data points from AnAge:
- Family classification
- Genus and species
- Common name
- Female and male maturity (days)
- Gestation/Incubation period (days)
- Weaning period (days)
- Litter/Clutch size
- Litters/Clutches per year
- Inter-litter/Interbirth interval
- Birth weight (g)
- Weaning weight (g)
- Adult weight (g)
- Growth rate (1/days)
- Maximum longevity (years)
Data Quality
AnAge employs strict criteria for data inclusion:
- Information is based on reliable, peer-reviewed sources
- Maximum longevity records are carefully verified
- Data points are standardized for consistency
- Records are regularly updated as new research becomes available
Our Presentation Process
- We extract data directly from the AnAge Database
- Format the information for clarity and readability
- Present the data in consistent units of measurement
- Maintain original scientific accuracy while making it accessible to general readers
Limitations and Transparency
We acknowledge that:
- Some species may have limited available data
- Longevity records may be updated as new information becomes available
- Not all data points are available for every species
- Wild and captive lifespans may vary significantly
Updates and Maintenance
We regularly check for updates to the AnAge Database to ensure our information remains current. Any significant changes or updates to the data are reflected on our website as soon as possible.
