Meet the princess parrotfish. This fish here is in the initial phase of development. The terminal phase will turn this fish into a blue, pink, and yellow beauty. Fun fact: these fish are sequential hermaphrodites. Each phase of the fish is characterized as one gender. The terminal phase of the fish will change to the opposite gender due to environmental cue, such as the loss of a dominant male. In that case, the fish will become a male to ensure the continuation of the species. Interesting, huh?
