If you love unicorns, chances are youâve heard of unicorn fish. Have you ever wondered if theyâre real, or if theyâre a myth like other unicorns?
Wonder no more! These are actual creatures that exist! They arenât mythical, they donât belong in stories and legends; they are swimming around in our seas, as real as any other fish out there! In some places, you can even have a unicornfish for dinner, though Iâm not sure that Iâd want to do that.
Real unicorns, even if in fish form, might sound very exciting, but before you go and grab your scuba gear and get splashing around, itâs worth understanding a bit about them. Unicornfish donât quite match up to the shiny white and rainbow creature many of us associate with unicorns, though they are beautiful creatures in their own right, and well worth watching if you get an opportunity.
Why Are They Called Unicorn-fish?
The first question to answer with these weird fish is where they get their name from â especially as they donât look much like unicorns! The simple answer is that they have a single horn on their foreheads, which is a bit like a unicornâs horn in appearance. The horn isnât much like a unicornâs in any other way, however. It can grow longer than 10 centimeters (~4 inches), but doesnât serve as a defensive weapon.
Not all fish within this genus have the horn, though they still carry the name. They do all have a pair of sharp spikes, where their tails meet their bodies. These spikes point forwards, and can be used both defensively and aggressively.
Unicornfish are the cousins of surgeonfish, according to Britannica. They are also sometimes called Sinungay, which Delishably says comes from the Filipino term âsungay,â meaning horn. Obviously, if unicornfish and sungay are its two most common names, this is the most notable feature about the fish, regardless of what language itâs being named in!
The fish are also very nippy swimmers. Theyâre flat-bodied, so they are designed for speed, and can whip through the water with surprising swiftness. I donât think they could outstrip their mythical cousins, but theyâre graceful and skillful swimmers, nonetheless.
What Do They Look Like?
Unicornfish can get quite big, around 3 feet in length, and are generally a dark brown color, probably to better blend with the ocean. They certainly arenât sporting rainbow manes or tails, and they lack the brilliant white coats which mythical unicorns are famous for.
However, as DiveAdvisor says, some unicornfish do have brightly colored spines, which perhaps makes them a little closer to their rainbow equine cousins. It lists these as Bluespines and Orangespines, so no prizes for guessing what colors their spines might be!
Some of the fish have white tails, which look very striking against their dark bodies. A little like a unicorn glimmering in the gloom of a forest, these are often the most visible part of the fish as they flash through the water.
Unicornfish have long, pointed faces and elegant tails which stream out in the water. Because of the spines on their sides, they can defend themselves, but they arenât generally aggressive, and will usually swim away rather than confront a predator. They are rather striking fish, being a slightly unusual shape, and theyâre certainly a fish Iâd love to see in person!
Where Do They Live?
Unicornfish are usually found in the Indo-Pacific region. They like warm seas, and coral reefs are their stamping â or swimming â ground. Many species arenât particularly territorial, and often cross large expanses of reef to find their food.
If youâre looking specifically to see them, the main areas they can be found in include the Indian and Pacific oceans, Hawaii, and some of the East Asian countries. Delishably also says that there have been claims they swim on the reefs in Japan, so theyâre a wide-ranging fish. The key is that they love warm water with coral, so they shouldnât be too tricky to locate.
If youâve ever seen unicornfish in the wild, weâd love to hear about where you saw them and what you thought of them. Do they live up to their mythical cousins? What else did you see at the same time?
What Do They Eat?
Unicornfish predominantly live on algae, which they can find on the reefs where they live. Like many other fish, they arenât particularly fussy eaters, and will feed wherever they can. Some will wait beneath other shoals of fish, hoping to pick up nutrients from any fecal matter, while others forage widely to get what they can.
Many unicornfish also eat weed, and will hide in patches of it if they feel threatened. Here, again, we can draw some links with their mythical cousins, grazing emerald grass in the fields above, while their real fish relatives nibble at weed swaying gently back and forth in the currents.
Unicornfish donât prey on other fish, and will avoid those bigger than themselves for fear of becoming dinner themselves. Their gentle, herbivore nature matches that of equine unicorns.
Unicorns Or Not?
Unicornfish donât quite satisfy many of the things we look for in actual unicorns. They arenât particularly bright or beautiful, and they donât possess magical powers. Their horns are often less impressive than the bright, spiraling horns we associate with unicorns, and may even be non-existent, or just a bump on the front of their heads. They arenât associated with luck or freedom or immortality.
They do, however, tend to swim with others of their kind in shoals, and they graze the vegetation around them just as unicorns do. They are swift and agile, and certainly not something you want to miss out on if youâre diving in areas where they are commonly found.
If youâve had the good fortune to see them before, or youâre hoping to see them soon, remember what youâll be able to tell your friends: Hey, Iâve seen a real unicorn⌠fish.
