Herp Food Web
No AI-generated answers. Built from real sources and fixed rules.What this meansClose
When you use this tool, no AI writes your answer. The result comes from rules we set ahead of time, applied to information gathered from sources such as field guides, scientific records and our own courses. It is not made up on the spot.
AI did help us build it: writing code, organizing information and drafting some of the drawings.
Pick an animal and see what it eats and what eats it. Every line is a real feeding record, from photos people shared on iNaturalist and from published diet studies, so you can click from frog to snake to hawk and see how connected it all is. It covers the reptiles and amphibians of the United States and Canada; pick your state or province to see the animals there.

Help keep these tools running
This tool, the free snakes course, the Primer and everything on our Resources page will always be free. If it helped you and you would like to help keep it running (and help us build the next one), you can pitch in. Everything given goes to LEARN, the nonprofit rescue that runs The Herpetology Collective, so it also helps feed, house and care for the animals we take in.
