Another fish that depends on the seagrass in the lagoon is the Mu’u, or Dusky rabbitfish. It is a tasty fish with few bones. Rabbitfish form large groups to breed. In these so-called “spawning aggregations”, the females release millions of eggs that are fertilized by the males. The fertilized eggs then drift into the ocean. After several months dense schools of juveniles come back to the lagoon.
