Species Identification Game

You are a marine biology intern joining a research team on the island of Bermuda in the Atlantic Ocean. Your goal is to correctly identify fish and plankton as quickly as possible. In each round you will identify 5 fish (for the Beginner round) or 5 plankton (for the Advanced round). Answer each question about the features of the organism you are looking at to work your way through the identification key. To view the Tree or A/B Identification Keys, click the arrow to expand that key.
