Somewhere between formal science and pure fun, a small number of animals ended up with names nobody would guess belong to a real, documented species.
A fish called the sarcastic fringehead. A beetle formally named Agra schwarzeneggeri. A sea snail whose scientific name is, quite literally, Colon rectum. These aren’t jokes or internet myths. They’re accepted, published scientific names and common names, chosen by real researchers who clearly had some fun along the way.
💡 Quick Fact
This guide covers why scientists sometimes choose playful names, followed by 20 real animals with genuinely curious names, and answers to common questions.
Why Some Animals End Up With Such Odd Names
Whoever formally describes a new species gets naming rights, as long as the name follows official taxonomic rules. That small amount of creative freedom is exactly where these names come from.

Playful Wordplay
Some names are puns or jokes that still meet formal naming standards

Pop Culture Tributes
A handful of species are named after celebrities or fictional characters

Once formally published, these names become permanent, official identifiers, regardless of how playful or unusual they might sound to the rest of us.
20 Animals With Genuinely Curious Names
Each of these is a real, documented species, however unlikely the name might sound.
1Blobfish
Famous for its droopy, gelatinous appearance, which only happens after being brought up from deep water. In its natural habitat, it looks far more like an ordinary fish.
2Sarcastic Fringehead
Named for its aggressive, wide-mouthed threat display used against rivals, which apparently struck researchers as looking sarcastic.
3Numbat
A small Australian marsupial with a name that sounds invented but refers to a real, termite-eating species.
4Quokka
A small, famously photogenic marsupial whose short, bouncy name matches its equally cheerful reputation.
5Shoebill
Named directly and simply for its enormous, shoe-shaped bill, one of the most distinctive beaks of any bird.
6Leafy Seadragon
Named for its leaf-like body extensions, which serve as remarkably effective camouflage among floating seaweed.
7Pink Fairy Armadillo
The world’s smallest armadillo species, with a name that sounds like it belongs in a storybook rather than a field guide.
8Star-Nosed Mole
Named for the unusual star-shaped ring of fleshy sensory tentacles surrounding its nose.
9Blue-Footed Booby
Named quite literally for its bright blue feet, used prominently in courtship displays.
10Dracula Ant
Named for its unusual habit of feeding on the blood-like hemolymph of its own larvae, rather than any resemblance to vampires.
11Exploding Ant
A group of ant species that can rupture their own bodies to release a defensive substance protecting the wider colony.
12Wunderpus Octopus
Its scientific name translates roughly to “wonder octopus,” inspired by its intricate, striking pattern.
13Vampire Squid
Its full scientific name translates to “vampire squid from hell,” despite being a harmless deep-sea cephalopod.
14Ba Humbugi
A snail species with a scientific name playfully referencing the phrase “bah, humbug.”
15Agra Schwarzeneggeri
A beetle species formally named as a tribute to actor and former governor Arnold Schwarzenegger.
16Ytu Brutus
A beetle genus with a scientific name playfully echoing the famous line “Et tu, Brute?”
17Colon Rectum
A real sea snail species whose scientific name is exactly what it appears to be, based on its shell’s shape.
18Aha Ha
A wasp species whose short, exclamatory-sounding scientific name has amused taxonomists for years.
19Boops Boops
The scientific name of the bogue, a common fish, which happens to translate loosely to “eyes eyes.”
20Han Solo (Trilobite)
An extinct trilobite species formally named in tribute to the Star Wars character, based on a resemblance researchers noted in its shape.
Frequently Asked Questions
Why do some animals have such strange scientific names?
+
Scientists who first formally describe a species get to choose its scientific name, and while many names describe a physical trait or location, researchers occasionally choose a pun, a pop culture reference, or a playful joke instead, as long as it follows formal naming rules.
Is the sarcastic fringehead’s name based on actual behavior?
+
The name isn’t based on true sarcasm, since fish don’t have that capacity, but rather on the fish’s aggressive, wide-mouthed display used to intimidate rivals, which researchers apparently found reminiscent of a sarcastic expression.
Are joke or pun-based scientific names considered valid and permanent?
+
Yes. Once a scientific name is formally published following official taxonomic rules, it becomes the permanent, valid name for that species, regardless of whether it happens to be a joke, pun, or pop culture reference.
Why does the blobfish look so different in its natural deep-sea habitat compared to photos?
+
The blobfish’s famously droopy appearance mostly shows up after it’s brought to the surface, where the sudden drop in water pressure causes its gelatinous body to collapse and sag. In its natural deep-sea habitat, it actually looks more like a fairly ordinary fish.
Do animals named after celebrities have any real connection to that person?
+
Typically not biologically. These names are usually a tribute or playful homage chosen by the researcher who described the species, often referencing a trait, sound, or simply the researcher’s personal admiration for that public figure.
Can anyone suggest or vote on a new species’ scientific name?
+
Generally, the researcher or team that formally describes a new species has the right to choose its scientific name. Some institutions do occasionally run public naming contests or auctions for naming rights, but the final decision must still follow official taxonomic naming rules.
Conclusion: Science Has a Sense of Humor Too
From the blobfish’s unfair reputation to a beetle named directly after Arnold Schwarzenegger, these 20 species are a reminder that scientific naming, despite its formal rules, still leaves plenty of room for personality.
Every name on this list belongs to a real, documented animal. The names might be funny, but the biology, and the researchers’ genuine enthusiasm behind each one, is entirely serious.
