Metazooa

The game

Metazooa is a daily biology puzzle about the animal kingdom. Find the Mystery Animal by making guesses and exploring our extended family tree.

Each guess reveals shared ancestry with the answer. The branching tree helps you narrow the search from broad groups toward a particular species, using relationships rather than physical distance or appearance.

The game uses the NCBI taxonomy. Classifications can differ between sources and change as scientific understanding develops. The FAQ explains the game's species selection and some common classification questions.
