15 Fin-tastic Facts About The Banded Butterflyfish For Kids

Interesting banded butterflyfish facts include that these fish are monogamous in nature.

Banded butterflyfish, Chaetodon striatus, also known by the names banded mariposas, butterbuns, butterfly fish, Portuguese butterflies, and schoolmistress, were first described by Carl Linnaeus in 1758. These reef fish are small and flat and oval in shape, with pointed snouts and sloping foreheads full of spines and fins on their body. The adult butterflyfish are white with strong vertical lines on their body with yellow highlights on their fins; however, the juveniles have darker colors and an eye-like spot on their dorsal fins, helping them confuse the predators from eating them. The banded butterflyfish are diurnal fish that are more active during the day and sleep at night. They also seek shelter at night from the predators like moray eels, sharks, and other reef fishes. Moreover, there are more than 130 species of butterflyfishes living in the world, most of which live in the coral reefs and many others in the deep ocean.

Banded Butterflyfish Interesting Facts

What type of animal is a banded butterflyfish?

The Chaetodon striatus, banded butterflyfish, is one of the butterflyfish species found in the world.

What class of animal does a banded butterflyfish belong to?

The Chaetodon striatus belongs to the Actinopterygii class of the family Chaetodontidae.

How many banded butterflyfish are there in the world?

The exact number of butterflyfish is not known, but since they are reef fish species of Least Concern conservation status, they are found in abundance in their habitat. It is believed that if a large number of butterfishes are seen diving, it indicates a healthy coral reef in that area since they require healthy corals as their food.

Where does a banded butterflyfish live?

Butterflyfish can be found in the western Atlantic from Massachusetts to Rio de Janerio, the Gulf of Mexico, and the Caribbean Sea. They can also be found off St. Pauls's Rocks in the central Atlantic.

What is a banded butterflyfish's habitat?

The banded butterflyfish habitat range mainly consists of coral reefs and is also associated with tropical marine reefs at a depth of 180.4 ft (55 m).

Who do banded butterflyfish live with?

This marine fish species can live alone or in pairs. Although sometimes the fish might also occur in small shoals of about 20 individuals for purposes of feeding.

How long does a banded butterflyfish live?

The lifespan of butterflyfishes ranges from three to possibly five years.

How do they reproduce?

The Chaetodon striatus fish are known to reproduce quickly, doubling their population every 15 months. Banded butterflyfish are known to be one of the monogamous fish species. The adults stay in the same pair for life. The courtship happens between the adults by the fish circling each other head to tail; after that, they would chase each other around the nearest coral reef, where the female would release 3,000-4,000 small and pelagic eggs. The reproduction takes place externally through spawning at dusk. The eggs hatch within a day, and the larvae are usually gray in color, which takes up the color of juveniles in the next 24 hours. The juveniles have a large ringed black spot on their fin that looks like a false eye, which confuses the predators as to which is their front side. Their overall body color is brownish-yellow instead of white. The juveniles change their color and lose the false eye as they grow into adults.

What is their conservation status?

Banded butterflyfish are a marine species of Least Concern conservation status. Even though they are harvested for the aquarium trade, their population is still in abundance. However, they face a coming threat since they rely a lot on the corals for feeding, which is affected due to climate change.

How do butterflyfish protect themselves?

The first instinct of a butterflyfish is to flee, but if they can't flee, they would assume a defensive posture.

It would seek shelter from the night predators such as sharks, moray eels, and other large reef fishes at night time.
