The messmate pipefish Corythoichthys haematopterus is a member of the family Syngnathidae and lives in monogamous pairs. Pairs of this species as well as of other closely-related monogamous pipefishes are known to perform greeting behavior. Every day during both reproductive and non-reproductive seasons, pair members meet at a pair-specific spot and exchange greeting behavior. Greeting behavior is restricted to a short period of time soon after sunrise and lasts for about 2-3 minutes. During the rest of the day, the pair members are separated with almost no contact. Greeting behavior is thought to play an important role in the maintenance of pair bonding. In the video picture, a heterosexual pair are repeating displays called "Both Arch" and "Cross".
