Common Questions

How accurate are the animal measurements?

All measurements are sourced from scientific databases including the IUCN Red List, Animal Diversity Web, and peer-reviewed publications. We use average adult measurements for each species.

What does "shoulder height" mean?

Shoulder height is measured from the ground to the top of the animal's shoulder (or withers). For birds, we use standing height. For snakes and fish, we use body depth or diameter.

Can I compare extinct animals?

We include some famous individual animals that have passed (like Jumbo the elephant), as well as species data. Our database is continually expanding.

How many animals can I compare at once?

You can compare up to 8 animals at a time. You can also toggle a human reference silhouette for scale.
