7) Blue streak cleaner wrasse, Labroides dimidiatus
Blue-streak cleaner wrasse can be found in the Indian, Pacific, and south Atlantic Ocean (Shea, S. & Liu, M.). These fish can be found near corals and reefs which provide them with shelter and protection. Female blue-streak cleaner wrasse are able to convert themselves into a male if the environment is more suitable for a male. The larger, more dominant female will change genders if the dominant male dies (“SEX CHANGE IN FISH FOUND COMMON”). This will occur so that school of fish can be reproductively sound during any environmental hardships. Researchers are unsure of how the females exactly change into a male but they know it is initiated through social interactions (“SEX CHANGE IN FISH FOUND COMMON”). They believe that hormones and certain genes are triggered to help the female fish change into a male. As they are changing their color, markings, and reproductive organs will alter to make them appear like a male. The last thing that they believe will occur is the start of sperm production in the new testes of the fish (“SEX CHANGE IN FISH FOUND COMMON”). This will allow the school of fish to reproduce efficiently and survive.
