Be careful around these colorful fish, however, as they can get aggressive when protecting their nest and have been known to bite divers. This fish is multicolored and has a gold outlined v near its tail, but perhaps the most distinctive feature is its little blue mustache over its upper lip. The reason the triggerfish has this long name is that it means “fish with a nose like a pig” in Hawaiian and this fish has been known to make noises like a pig when it is stressed. They are found in most reefs off the coast of Hawaii so you are very likely to see one of these on your snorkeling trip!Īlthough your state may not have a state fish, Hawaii sure does! Its real name is Humuhumunukunukuapuaa, which is quite a mouthful and the reason people typically call it a triggerfish instead of its full name. What you may not know is that these fish can actually get quite large, up to 8 inches in diameter. They are black, white, and yellow and have vertical stripes. Have you seen the animated movie Finding Nemo? Then you are likely familiar with this type of fish as it will look just like Gill from the movie. The Most Popular Hawaiian Fish Types Moorish Idol Read on to learn more about Hawaiian fish names. You will see several species of coral and some amazing and colorful fish.īut what types of fish are you seeing? Or maybe you are wondering what type of fish you saw on your recent snorkeling trip. It already fully displays two anterior stripes, on the head and trunk, while a third is forming on the tail.Snorkeling in Hawaii is an unforgettable experience. bicinctus.įifteen-day-old juvenile clown fish (A. Four species of clown fish (genus Amphiprion), clockwise from top left: A. Species differ in the number of white stripes they display: zero, one (head), two (head and trunk), or three (head, trunk, and tail). The full spectrum of clown fish colors is not limited to orange or red but ranges from yellow to black. This should clue them in to the processes behind color diversification and the role color plays in the social organization of reef fish. The research team would like to follow up by identifying the genes that control the acquisition of white stripes for a greater understanding of how they evolved. Over the course of evolutionary history, some species of clown fish gradually lost stripes, resulting in today's range of color patterns. Just like today's clown fish, these ancestral stripes were made up of pigmented cells called iridophores containing reflective crystals. They discovered that their common ancestor sported three stripes. In an attempt to understand the origin of these patterns, the scientists delved into the evolutionary history of clown fish. The team further observed that some stripes are occasionally lost between the juvenile and adult stages, this time beginning at the tail end. Stripes appear one at a time, starting near the head and progressing towards the tail, during the transition from the larval to the juvenile stage. The researchers then deciphered the sequences of stripe appearance and disappearance during the life of a clown fish. Such recognition is critical to the social organization of clown fish living among sea anemones where several species may be simultaneously present and young fish seek to establish permanent homes. The team first demonstrated that stripes are essential for individual fish to recognize others of their species. These researchers focused on clown fish, a group including thirty-some species distinguished by numbers of white stripes (zero to three) and by their colors, including yellow, orange, red, and black. Coral reef fish are known for the wide range of colors and patterns they display, but the mechanisms governing the acquisition of these characteristics are still poorly understood.
