Did you know?

  1. The cleaner wrasse removes parasites, dead skin and bits of food from the fins, gills and skin of reef predators.
  2. Cleaner wrasses would even swim into the mouth of a shark to remove gunk from their teeth.
  3. Cleaner wrasses have been observed offering “massages” to their host animals. Scientists believe this tactic encourages the hosts to linger for cleaning.
  4. The cleaner wrasse wiggles its body and jiggles its tail to tell other fish it’s ready to work. Other fish line up for clean-up when they see the wrasse’s dance.
