Weird Scientific Names for Fishes

The naming of fish species has always been a job best done by scientists. But, every once in a while they come up with a fish name that is weird, funny, and sometimes - rather rude.

This section contains a list of unusual and funny scientific names for fishes, and the thought process behind these weird names for marine animals.

Marine Animals with the Weirdest of Names

There are 1,305,075 extant invertebrate species on earth - according to estimates from the International Union for Conservation of Nature (IUCN).

In addition, the number of vertebrate animals with a spinal column is thought to be around 62,000.

Here's the thing:

A recent tally of living fish species is said to be about 33,000 - and the marine biologists had to come up with an "appropriate" name for every single one of them!

So, our team thought it would be a good idea to list fish names that are either humorous, comical, unfathomable, or downright risqué!

We hope you get a giggle somewhere down the page and please send us an email if we missed anything funnier or weirder.

In no particular order...

Bombay Duck (Harpadon nehereus)

There are several obscure names used for this lizardfish, including bummalo, loitta, boomla, bombili, and lote.

Archives suggest Robert Clive (first British Governor of the Bengal Presidency) first coined the term after tasting its flesh during his conquest.

The Bombay duck fish is a significant annual catch from the waters off Maharashtra, in the Lakshadweep Sea.

Fun Fact: Several decades ago, the UK consumed 13 tonnes of Bombay duck each year. But, in 1996 the European Commission banned fish imports from India after the discovery of contaminated seafood. Later, the 'Save Bombay Duck' campaign persuaded the EU to adjust their strict regulations.

Sarcastic Fringehead (Neoclinus blanchardi)

This funny fish name sounds more like an 80s rock band. But, N. blanchardi are types of blenny fish found in huge numbers along the coast of California.

Sarcastic Fringehead (Neoclinus blanchardi)It's a 'deceptively' small creature, and it would be rare to see them longer than twenty five (25) centimetres (10 inches).

But, make no mistake, sarcastic fringeheads are both fearless and aggressively territorial.

It will make a charge towards anything that gets anywhere near its burrow.

Scientists must have witnessed their temperament when they attributed the common name 'sarcastic'. And the fringehead part? It has to be the distinctive supraorbital appendages on top of their eyes.

Further research suggests that the 'spectacularly ugly' sarcastic fringehead (Neoclinus blanchardi) uses its colourful mouth to communicate.

Lumpsucker Fish (Cyclopterus lumpus)

There can only be one reason why a zoologist would call a fish species 'lumpsuckers'. This lumpy fish looks like a ball and it has a special sucker for sticking onto rocky substrates.

Having a portly, globular body shape helps to protect the lumpsucker fish (Cyclopterus lumpus) against the breaking waves in the cold waters of the North Atlantic.

The lumpfish sucker is an adaptation of fused pelvic fins. Most of the male species have some kind of bony tubercles, often appearing as wart-like decorations on the head and body.

Slippery Dick Wrasse (Halichoeres bivittatus)

So, let's keep things polite and very professional. In fact, Halichoeres bivittatus (slippery dick fish) is one of the 500+ species of wrasses.

Slippery Dick Wrasse (Halichoeres bivittatus)You will find many of them thriving in shallow waters from Bermuda to Brazil (e.g. the western Atlantic Ocean).

But, why would anyone with a good command of the English language name a fish 'slippery dick'?

Here's the answer.

This - shall we say 'out of the ordinary' - name for a fish, derives from its ability to secrete a slick, slimy mucus from its skin to evade capture.

In fact, even anglers find it challenging to handle this greasy fish due to their speed and agility in escaping fishing nets and their natural predators - lionfish.

Pro Tip: You can read more about the different wrasse types (Labridae) in the section that covers marine vertebrates.

Higgins' Eye Pearlymussel (Lampsilis higginsii)

This rare species is actually a freshwater mussel. It is endemic to areas of the upper Mississippi River and the drainages of a few of its tributaries.

In fact, the life history of these marine bivalve mollusks matches the uniqueness of the moniker. It was the first freshwater mussel to get federal protection back in 1972.

Humuhumunukunukuāpuaʻa (Rhinecanthus rectangulus)

Let's state the easy names first. The most common name for it is the reef triggerfish. Some refer to it as the rectangular triggerfish, or even the wedgetail triggerfish.

Humuhumunukunukuāpuaʻa (Rhinecanthus rectangulus)Now, let's try the unpronounceable name that native Hawaiians use... Humuhumunukunukuāpuaʻa.

Moving on...

Obviously, you can find this fish in Hawaii. But it's also found at some of the coral reefs in the Indo-Pacific

In a nutshell, the Hawaiian word means "triggerfish with a snout like a pig".

Following a campaign in 2006, the Governor reinstated this colourful fish as being the official state fish of Hawaii once again. They even added the lyrics "where the humuhumunukunukuāpuaʻa go swimming by' to a song.

Coffinfish (Chaunax endeavouri)

I guess we shouldn't expect marine biologists to give elegant labels to sea toads. But, coffinfish? Really?

Not only is this a weird name for a sea creature, but they look a little strange too. Maybe that's why they are not targeted by commercial fisheries.

Key takeaways:

The coffinfish (Chaunax endeavouri) is capable of holding its breath for four (4) minutes at rest, deep on the ocean floor.

In fact, after inhalation the gills of this sea toad are so big that it can increase its body volume by 30%. To compare, humans would need to inflate their lungs to a size so big that they would match the size of the entire abdomen.

However, that doesn't really tell us why someone named more than twenty different species of coffinfish - coffinfish. One reason could be that this type of anglerfish uses its fins to 'walk' deep down to depths over two kilometres (8,200 feet) on the floor of the ocean.

Dumb Gulper Shark (Centrophorus harrissoni)

There are only a handful of dive spots around the world where this endangered deepwater dogfish exists (e.g. the east coast of Australia and the west of New Zealand). In fact the locals call it:

  • The dumb shark
  • Harrison's deep-sea dogfish
  • Harrison's dogfish

So, is the dumb gulper shark (Centrophorus harrissoni) a worthy contender for this list of marine animals with the weirdest of names?

If so, its pseudonyms must come from the way that it communicates with other animals, such as opening its jaw and head nodding used as gestures.

Red-Lipped Batfish (Ogcocephalus darwini)

The picture shows how appropriate it was for scientists to classify it as the red-lipped batfish. Plus, being a resident of the Galapagos Islands means the locals also dubbed it as the Galapagos batfish.

Red-Lipped Batfish (Ogcocephalus darwini)Some of the distinctive features include the bright red, sullen, pouty lips and 'bat-shaped' bone structure.

In fact, beyond the lipstick aesthetics, biologists think the fish uses the hue for communication and during its courtship rituals.

It might appear odd to some, but this unique feature in red-lipped batfish (Ogcocephalus darwini) may signify a readiness to mate.

There are about sixty different species of batfishes, and this one has modified pectoral and pelvic fins. Yes, they can swim. But, they can also walk (more like a shuffle or a wobbly dance) on the seafloor.

Obese Dragonfish (Opostomias micripnus)

The poisonous obese dragonfish (Opostomias micripnus) is one of the largest Melanostomiidae (around 50 centimetres long). Furthermore, it can exist in very deep water - we're talking five kilometres deep.

This deepwater pelagic species has large, fang-like teeth and a long, ugly barbel. It seems to thrive well in the dark abyss environments of the Atlantic, Indian, and Pacific Oceans.

But, it's not a pretty fish, hence the dragonfish reference in the title. And the obese part? Well it does have a pot belly and you wouldn't want to take it home to meet your mom!

Wunderpus Octopus (Wunderpus photogenicus)

It's known as the Wunderpus octopus (Wunderpus photogenicus) because of the German word 'wunder' - which kind of means wonderful or marvellous. But, I guess you already knew that - right?.

Wunderpus Octopus (Wunderpus photogenicus)Like most of the octopi species, it has long arms that are good at mimicking other shapes and creatures in the sea.

But, it's important not to confuse the copper-brown colouring and spectacular patterns with that of the mimic octopus - they are not the same.

In fact, the wonderful wunderpus has a unique white spot on its mantle.

Features such as these, help biologists study and identify different animal and fish species - before naming them.

This particular species is quite new to science literature. Even though they discovered it in the 1980s, they didn't allocate its common name (and 'officially' described it) until 2006.

Oyster Toadfish (Opsanus tau)

Biologists named this ugly Northeast Atlantic fish specimen after two different animals, but it has a whole host of alternative common names, including:

  • Bar dog
  • Oyster cracker
  • Oyster catcher
  • Oyster toad
  • Ugly toad

It's known for living in the most uninhabitable conditions you could imagine. For example, they are almost invisible in murky waters and muddy oyster beds while they wait to catch their prey.

Pro Tip: NASA sent the Oyster Toadfish (Opsanus tau) into space in 1998. They wanted to test the effects of microgravity on otoliths (balance and hearing organs).

Bloater (Coregonus hoyi)

Even if you belong with the species of freshwater whitefish (subfamily Coregoninae), being called bloaters is not a nice thing right?

They pegged this amusing term to a fish that's native to the very deep waters (198 metres or 650 feet) of all the Great Lakes, except one (Lake Erie).


In a nutshell, these fish would have a 'bloated' appearance when fishers were bringing them up in nets. At one time, the population suffered - primarily due to the sea lamprey vampire fish and the invasive alewife (Alosa pseudoharengus). But, bloater populations are 'swelling' again - especially in Lake Ontario.

Slimehead (Hoplostethus atlanticus)

Calling anything 'the slimeheads' sounds like a bit of an insult - and definitely not something you would put on the dinner table. So, seafood marketers rechristened them to (take your pick):

  • Slimehead (Hoplostethus atlanticus)Redfish
  • Orange roughy
  • Roughies

In fact, the funny common name relates to the mucous-producing canals on top of the fish's head.'

While we're on the subject of amazing fish facts. The slimehead (Hoplostethus atlanticus) waits until they are more than twenty years old before they start reproducing. Plus, reports suggest they can live for nearly 150 years.

Spotcheck Stargazer (Ichthyscopus sannio)

Yes you guessed it - spotcheck stargazers (Ichthyscopus sannio) are a spotty fish and they are a member of the stargazer fish family.

So, they are good at burying themselves in the sandy substrate and using the eyes situated on top of the head to locate prey.

Tasselled Wobbegong (Eucrossorhinus dasypogon)

You can find this bottom-dwelling species of carpet shark in the shallow reef areas of Australia, Indonesia, and the western Pacific.

Tasselled Wobbegong (Eucrossorhinus dasypogon)The 'tasselled' stamp refers to the dangling tassels that surround the periphery of its head. It kind of looks like side whiskers or a colourful beard.

The wobbegong part?

We understand that it comes from an Aboriginal word that probably translates to something like 'living rock'.

Most carpet sharks are small, measuring about one metre in length (4 feet). The tasselled wobbegong (Eucrossorhinus dasypogon) is one of them that rests motionless on the bottom of the ocean waiting for an easy meal.

Pirate Perch (Aphredoderus sayanus)

The forward placement of its cloaca is one of the quirky features about this small freshwater fish. Another one is the use of crypsis (chemical camouflage) to avoid detection.

Why is it called a pirate perch (Aphredoderus sayanus)? Early observations of it eating other fish species is the best answer. Even though the funny fish name stuck, it actually eats the larvae of aquatic insects.

Monkeyface Prickleback (Cebidichthys violaceus)

The monkeyface prickleback (also called monkeyface eel) is the last inclusion in this list of funny scientific names for fish species.

Monkeyface Prickleback (Cebidichthys violaceus)The species, which is actually a fish and not an eel, is widespread around the coastal areas of central California.

The derogatory, yet amusing, name comes from its monkey-face-like demeanour and appearance.

But, there's a lot more to learn about the monkeyface prickleback (Cebidichthys violaceus) - a remarkable specimen.

The life expectancy of these fish is something close to fifty (50) years. So, they must enjoy living in rocky, intertidal habitats.

Their staple diet includes several examples of marine invertebrates, including marine mollusks, and aquatic crustaceans

Finally, they are sequential hermaphrodites that start their life as a female. As they develop and get older, some will transition into males in preparation of the breeding process.
