About Beastsora
A scientifically grounded animal comparison engine built to replace speculation with data.
What Beastsora is
Beastsora is an animal comparison engine covering 48 species across terrestrial and aquatic environments.
Each profile includes body mass, top speed, bite force, aggression, endurance, intelligence, and conservation status. These metrics are compiled from identifiable zoological sources.
Users can compare any two animals head to head, explore species rankings by metric, or run a human versus animal survival assessment. Every matchup is scored using a weighted model designed to reflect biological reality rather than opinion.
Beastsora is an independent project focused on making wildlife data easier to explore and understand.
Why it exists
The question "who would win in a fight?" appears everywhere online. Most answers rarely cite sources or acknowledge uncertainty in the data.
Beastsora was created to fill that gap. The goal is to make animal comparisons entertaining while also showing the biological factors behind the outcome.
Wildlife data should be accessible and honest. That means identifying sources, acknowledging when measurements are estimated, and refusing to fabricate numbers to fill missing data.
How data is gathered and reviewed
Each animal profile is compiled from multiple authoritative references. These include peer-reviewed journals, the IUCN Red List, NOAA Fisheries, the Smithsonian Institution, and natural history museum datasets.
When sources disagree, the disagreement is documented rather than hidden. The goal is transparency rather than artificial precision.
Profiles include a data quality label that indicates how well documented the species is in the scientific literature. Labels include Verified, Mixed-Evidence, and Limited Data.
Each metric also carries a confidence level of High, Medium, or Low. This reflects the quality and consistency of the underlying measurements.
Profiles display a review date. Data is periodically checked as new studies are published or conservation assessments are updated.
On estimates and unknowns
Some animal metrics cannot be measured directly in the field.
Bite force is often estimated using biomechanical modelling rather than measured from living animals. Top speed measurements are usually recorded under specific conditions and may not represent a true biological maximum.
Aggression and intelligence values are normalized comparative scores rather than objective measurements.
When a value is estimated, the page states this clearly. When reliable measurements do not exist, the metric is left blank. Beastsora does not substitute guesses for missing data.
Each profile documents measurement limitations in its Data Integrity section.
How matchups are scored
Win probability is calculated from seven weighted factors:
- •physical size and mass
- •top speed
- •bite force and natural weapons
- •endurance
- •aggression
- •intelligence
- •habitat advantage
The model is based on comparative biology principles used in zoology to analyze size, weaponry, speed, and ecological adaptations between species.
The model simulates a single encounter between two healthy adult animals.
It does not account for individual variation, disease, age, injury, or the many variables that influence real-world predator interactions. The result should be understood as a scientific estimate rather than a prediction.
Full methodology and scoring weights are explained on the methodology page.Data Integrity
Beastsora does not generate or fabricate animal measurements.
When reliable primary data cannot be found, the metric is marked as estimated or left blank. Unknown values are not replaced with guesses.
The goal is transparency about the limits of wildlife measurement while still presenting the best available data.
