921 species with licensed reference photos
How this library is built.
The catalog is a living record, and its rules are stricter than its size.
Licensed photography onlyA species appears here only once it carries a reference photo with a named creator, source, and reuse license. The credit renders on every card.
Grown by exploringWhen explorers scan something new, it joins the publication queue: the profile is drafted, a licensed photo is sourced, and only then does the entry go live.
Checked and correctableIdentifications ship with confidence scores and alternatives, and a correction pipeline routes disputed matches back for review.
A sourced editorial layerA growing set of species carries editorial field guides with explicit sources and lookalike notes — the profiles below, built to be checked and corrected.
Editorial field guides.
