A-Z Animals was founded on three guiding principles: accurate content you can trust, spreading knowledge on the animal kingdom, and giving back. Today, more than 30,000 species are threatened with extinction, and thousands would already be lost without tireless conservation efforts. Knowing that the first step toward conservation is spreading knowledge of the incredible animals species across our planet, A-Z Animals was founded in 2008 to offer an online encyclopedic resource across animals of all kinds.
