# The Fauna Archive

> The Fauna Archive is an independent editorial publication covering animal facts and wildlife guides: how fast, how long, what they eat, and how they live. Every species fact is stated as an honest range drawn from well-established natural-history knowledge — no inflated records, no invented studies.

The Fauna Archive publishes original, long-form guides about animal facts and wildlife guides. Every article opens with a concise direct answer, is structured with clear headings and FAQs, and reflects mainstream expert consensus.
