Sources we use
Every species page and guide lists the references we checked. Here they are in one place, grouped by website.
We prefer primary and specialist references (scientific databases, species-focused sites and long-running keeper communities) and use the conservative, widely accepted hobby value when sources disagree. Read our editorial policy and method.
