Meet the Black Pyramid Butterflyfish
The black pyramid butterflyfish is a small fish. It can grow up to about 18 cm long. That's about the length of a ruler!
What Does It Look Like?
This fish has a body that is flat from side to side. It looks rounded when you see it from the side. Its snout is a bit long, and it has a small mouth that can stick out.
The fish's body is mostly black. A wide white band crosses its middle. This band looks like a trapezoid and has a yellow top. This yellow part is near the middle of its dorsal fin (the fin on its back). Its caudal fin (tail fin) is white.
Where Do These Fish Live and What Do They Do?
The brown-and-white butterflyfish lives in warm, tropical parts of the Indian Ocean. You can find it from the eastern coast of Africa all the way to Java in Indonesia. It also lives near India and Mauritius.
Their Ocean Home
These fish love to hang out in large groups called schools. They live on the outer slopes of coral reefs. This is where the reef drops off into deeper water. They can swim out into the open water to find food.
What's on the Menu?
The brown-and-white butterflyfish eats tiny sea creatures called plankton. Plankton are like the microscopic snacks of the ocean. These fish usually live at depths of 3 to 40 meters.
The Story Behind Its Name
Every living thing has a scientific name. This helps scientists around the world know exactly which creature they are talking about. The scientific name for this fish is Hemitaurichthys zoster.
Who Named This Fish?
An English zoologist named Edward Turner Bennett first described this fish in 1831. He first called it Chaetodon zoster. The fish was found near Mauritius.
What Does "Zoster" Mean?
The word zoster in its name means "belt" or "girdle." This name probably refers to the wide, white band that looks like a belt around the middle of the fish's body.
Is This Fish Kept as a Pet?
The brown-and-white butterflyfish is not very common in the aquarium trade. This means you won't often see it for sale in pet stores.
How Are They Doing in the Wild?
The brown-and-white butterflyfish eats plankton. Sometimes, changes in the climate can affect how much plankton is available. This could impact the fish's food supply.
However, there are no major threats to this fish right now. Because of this, the IUCN (International Union for Conservation of Nature) lists it as a Least Concern species. This means they are not worried about it becoming endangered anytime soon.
