The Ctenochaetus flavicauda, also known as the whitetail bristletooth or redspotted tang, is a cool fish that lives in the ocean. It's part of a group of fish called Acanthuridae, which includes surgeonfishes, unicornfishes, and other tangs. You can find this fish swimming in the western central Pacific Ocean.
About This Fish
The whitetail bristletooth was first officially named and described in 1938. An American scientist named Henry Weed Fowler gave it its scientific name. The very first fish of this type that scientists studied was found near Takaroa in the Tuamotu Islands, which are part of French Polynesia. This special fish was collected during a big trip called the George Vanderbilt South Pacific Expedition in 1937.
This fish belongs to the larger family of fish called Acanthuridae. This family includes many interesting fish like surgeonfish and unicornfish.
What's in a Name?
The scientific name Ctenochaetus flavicauda has a special meaning. The part flavicauda means "yellow tail." This name was chosen because when the fish was first described, its tail was said to be a "brilliant yellow." However, other scientists later described its tail as being pure white. So, its common name, "whitetail bristletooth," fits it well!
What It Looks Like
The whitetail bristletooth is a pretty fish! It has a reddish body with many bright blue spots on its head. These spots then turn into blue lines along its body. One of the most striking things about this fish is its tail fin. It's a brilliant white, which really stands out against its colorful body.
This fish can grow up to about 16 centimeters (about 6 inches) long. That's roughly the length of a standard pencil! Its fins are supported by special spines and soft rays, which help it swim and move through the water.
Where It Lives
You can find the whitetail bristletooth in the central Pacific Ocean. It lives in a wide area, from the Phoenix Islands in the north all the way down to the Austral Islands and Rapa Iti in the south. It also stretches east to the Pitcairn Islands and north to the Line Islands.
This fish loves to live on coral reefs. It can be found in waters as deep as 30 meters (about 100 feet). Coral reefs are like underwater cities, full of different kinds of marine life, and the whitetail bristletooth is one of its colorful residents!
