Big Forehead Fish

Animal with enormous foreheads are always a joy to watch. They appear ridiculous, and we can’t help but chuckle at our odd-looking uncle Stanley (thank goodness we didn’t inherit our foreheads from him).

Did you know that there are even more fish with large foreheads than there are land animals with enormous brows?

Several species of dolphinfish, napoleon fish, humphead parrotfish, oranda, humphead glassfish, unicornfish, and others are among them. Let’s look at all of these creatures and show you what they are.

Napoleon Fish

The forehead of Napoleon fish, also known as humphead wrasse, is massive. It has the appearance of a beluga whale’s forehead.

This fish grows to be six feet long and weighs roughly 420 pounds when fully grown.

Surprisingly, the forehead of the Napoleon fish earned it its name. The protruding forehead resembles the hat of deceased French emperor Napoleon Bonaparte, according to the scientists who named it.

When the napoleon fish grows older, its head hump becomes more pronounced. Their forehead is not the only feature about them that interests me.

Napoleon fish is a hermaphroditic fish that can change sex depending on how it feels.

Blobfish (Psychrolutes marcidus)

The blobfish (Psychrolutes marcidus) was chosen as the mascot for the Ugly Animal Preservation Society by a public vote in 2013. The fish lives off the coast of Australia and is currently endangered due to being caught in deep-sea trawler nets as a byproduct of fishing for other species.

In a very high-pressure environment, the blobfish lives in the deep sea, and it looks considerably less repulsive in photographs taken out of water.

Its habitat, where its squidgy flesh allows it to maintain buoyancy at depths that gas-less bladders (the conventional fish organ for adjusting depth) are unable to function, is adapted with its slimy, gelatinous look. It also has a cool name, which we have featured in our list of amusing animal names.

Goblin Sharks

That’s not a banana, it’s my nose! Even at the cost of looking quite strange, some fish have created extended nose structures known as rostrums that serve as electrosensory organs.

Due to murky or dark conditions where they are commonly found, goblin sharks and Paddlefish exemplify this, most likely due to a lack of visual sight of prey.

A single plankton’s muscle twitch can be detected by paddlefish rostrums, which are incredibly sensitive to electrical pulses. By also using the electrosensitive rostrum as a weapon, sawfish have taken the electrosensitive rostrum to a whole new level.

Dolphinfish

With their forked-tail fins, massive faces, blunt faces, and prominent foreheads, these ocean fish are easily recognized from others.

Humans are not afraid to fish for them, even with their bulbous foreheads. In various nations, they are considered a delicacy.

North and South America, the Indian Ocean, Southeast Asia, and a few Pacific Ocean islands are home to Dolphinfish, a common breed.

In identifying a dolphinfish as a male or a female, their forehead is also valuable. Protruding foreheads are seen in male dolphinfish, whereas rounded foreheads are seen in female dolphinfish.

Green Humphead Parrotfish

Another large fish with a projecting forehead is the green humphead parrotfish. It weighs about 165 pounds and grows up to five feet tall.

The Pacific and Indian Oceans are home to this kind of parrotfish.

The parrotfish’s forehead is used to eat food, which is unusual. The green humphead parrotfish breaks coral into pieces for easier digestion with the help of its forehead hump.

The humphead parrotfish aids reef-building coral, despite the fact that it appears to be a danger to corals.

The algae that this vast fish consumes allows the coral reefs to flourish and maintain their diverse coral reef ecosystem.

According to another theory, the green humphead parrotfish headbutts rivals with its hump.

Frilled Shark (Chlamydoselachus anguineus)

The deep Atlantic and Pacific seas are home to the frilled shark (Chlamydoselachus anguineus), which is a relatively uncommon shark. Due to its primitive eel-like characteristics, such as the color, length, and location of the back fin, it is considered a living fossil.

The frilled shark maneuvers like an eel while hunting, bending and lunging with its prey. It has unusually wide jaws that can swallow large prey whole because of the 300 curved, needle-like teeth installed on them. Both dangerous animals and unattractive ones exist!

Hammerhead Sharks

Have you ever noticed how a shark appears to need to use one of those pore-cleansing strips when you get up close and personal with it? So, those are Ampullae of Lorenzini, not blackheads! What do you mean? Sharks and other species of fish can detect electric fields and temperature gradients caused by their prey’s muscle contractions thanks to these jelly-filled pores, which are really electroreceptors.

These are occasionally used to detect creatures buried in the sand, according to reports. The unique sensing mechanism may now be used to navigate using the earth’s geomagnetic field, according to more recent studies. To better detect prey with the Ampllae of Lorenzini, Hammerhead Sharks have large surface areas on their heads.

Kamfa

Kamfa is a freshwater fish with a big forehead.

It’s a flowerhorn fish, a freshwater crossbreed derived from several different kinds of fish. It does not have a scientific name and is not recognized as a distinct species because it was created by humans.

Kamfa has a square, white, or yellow body with a huge bump on its head that resembles a forehead. It has square, white, or yellow eyes.

Shrimp, worms, insects, and plant stuff are all eaten by kamfas, who are omnivores. They’re often misidentified as Zhen Zhu, a different kind of flowerhorn fish.

The coloration of flowerhorn cichlids ranges from pink to orange to red to gold to grey to black, with silver markings on their flanks. A KOK, which is made up of fatty tissue and water, is the hump on their foreheads.

Midas Cichlid

Another sea creature with a large, protruding forehead is the Midas Cichlid.

This goldfish lookalike measures about 35.5 centimeters long and weighs approximately 2.5 pounds.

The nuchal hump is the golden fish’s lump on its forehead. That’s odd, since adult Midas cichlids are the only ones that have it.

During the mating season, the nuchal hump, a hormonally generated forehead swelling, inflates on males.

The nuchal hump on a male Midas cichlid is larger than that of a female. This protrusion is barely visible on the female Midas cichlid.

During the breeding season, the nuchal lump is generally only present. Midas cichlids, on the other hand, were said to have a permanent nuchal bump on their forehead while living in aquariums.

Fortunately, no one has reported having such distinctive physical traits thus far.

Angler Fish (Linophrynidae)

Not just the ugliest fish, the angler fish (Linophrynidae) is possibly the planet’s most unattractive animal. It has a huge head with crescent-shaped mouths complete with numerous pointed, translucent teeth and lives in the deep, lightless depths of the Atlantic and Arctic oceans.

They are one of several types of bioluminescent creatures with their name derived from the fleshy portion of their dorsal fin that projects above their mouth and illuminates. Anglerfish come in a variety of colors and sizes, ranging from black to brown and measuring from 0.3 to 1 meter in length.

Male Cichlid Fish

That large bump on the head is actually a nuchal hump, also known as a kok, and it appears that this fish swam straight into a ledge and acquired the worst scrape ever. This forehead bulge enlarges on male cichlid fish just before they mate, and it is hormone-induced.

They are often smaller than the male bumps and only occur on females of certain species. The function of a nuchal hump has been attributed to two possible purposes: sexual recognition or storing fat. So, whether you see a cichlid with a bulging forehead or not, you’ll know he’s in desperate need of a dip.

Green Humphead Parrotfish

Another gray and green ocean fish with a large forehead is the greenhumphead parrotfish. It may reach 4.9 feet and 165 pounds, making it the biggest parrotfish species.

Adults of the humphead parrotfish may headbutt corals to get at benthic algae, which they consume. The Pacific, Indian, and Atlantic oceans all have coral reefs where greenhumpheads may be found.

Because of their odd mouths, which resemble a beak, all parrotfish share the same family name.

Orandas

The forehead of the oranda goldfish protrudes. The protruding bump, on the other hand, is more like a mirage than a forehead.

The hood of this tall tail fish gives the appearance of a bumpy forehead, and it has a bubble-like head. Oranda’s head expands as it ages.

Oranda may live up to 15 years and grow up to 30 centimeters in length.

The body of this fish is usually silver, and the head is crimson. With this color contrast, it appears that the oranda’s head is a raspberry.

Other oranda species, such as the black goldfish, have foreheads that are lumpy.

Red-lipped Batfish (Ogcocephalus darwini)

The red-lipped batfish (Ogcocephalus darwini) is a little fish that some people think is rather unusual, but others find attractive. This fish has an odd-shaped body, a “beard” and “mustache,” large “nose,” and their piece de resistance, bright red pouting lips. It is found around the Galapagos Islands and near the South American coast near Peru. The red-lipped batfish may be able to find a mate thanks to these lips, according to scientists.

Red-lipped batfish are unusual in that they prefer to ‘walk’ on the ocean floor, rather than swim gracefully. Their dorsal fin is employed to attract prey rather than for swimming once they reach maturity.

Front Cichlid

Lake Tanganyika is home to this east African fish species. The term “frontosa” comes from the cichlid’s unusually broad forehead, which is full of fat deposits. The cichlid is commonly known as Frontosa Cichlid or Frontosa.

They have five to seven black vertical bars over a white or blue body and head, with trailing fins that have a distinct blue tint. They are easy to spot.

It dwells among the rocks and feeds on fish, snails, and mussels in groups that live at depths of 35 to 170 feet.

Humphead Glassfish

The humphead glassfish is the last of our list of animals with large foreheads.

The freshwater of Thailand and Burma is home to this 10-centimeter fish.

The humphead glassfish, like its name suggests, blends in well in its environment. It has no trouble swimming around since it has an almost clear body.

All humphead glassfishes have forehead bumps that stick out due to genetics. The forehead bump of a male glassfish, on the other hand, is bigger than that of a female.

The humphead glassfish has a thinner hump than cichlids in comparison. Its forehead appears more like a fin than a normal forehead when viewed up close. For freshwater aquariums, the humphead glassfish is a popular pet.

Monkfish (Lophius)

The monkfish (Lophius) is a bottom-dwelling fish that also goes by the names sea-devils, fishing frogs, frog frogs, and ‘poor man’s lobster’ in the western and northern Atlantic Oceans. The monkfish has mottled skin with little eyes, enormous heads, and lips, and rows of fang-like overbiting teeth, which are all attributes that relate to the monofish’s – let’s face it – unattractive looks.

Despite their unattractive appearance, these fish are increasingly recognized to be immensely delicious, and they are becoming more common on the menus of high-end eateries and beyond.

Lionhead Cichlid

African blockheads, buffaloheads, and humphead cichlids are all names for lionhead cichlids.

These large-headed fish are endemic to Pool Malebo and the Congo River, where they breed in caves.

Elongated and robust bodies, enormous heads, and nuchal humps that expand with maturity in males distinguish them.

Sloane’s Viperfish

Sloane’s viperfish (Chauliodus sloani) lives in virtually all marine environments in the temperate and tropical oceans, ranging from 1,000 to 2,000 meters.

They hold a Guinness Book of Records record for having the largest teeth relative to their head size, and they are not only a unattractive fish (but well deserving of a spot on this list). The Greek terms chaulios (meaning “open-mouthed”) and odous (meaning “teeth”) are actually the origins of their name.
