You know which animals move in packs, schools, and herds, but what about a wake, a business, or a flamboyance?

1. A CACKLE OF HYENAS

While clan is the much more accepted term, there's something very appropriate about cackle. And though their laughs and giggles sound entertaining, they're really how spotted hyenas express anger, frustration, and warnings to stay away.

2. A SHREWDNESS OF APES

This term has around since the late 1400s—at the time, shrewdness referred to the mischievous nature of apes, though knowing now how intelligent they are, the term still works.

3. A RAFT OF OTTERS

According to the Oxford English Dictionary, many aquatic animals, such as ducks or puffins, also form rafts.

4. A MURDER OF CROWS

In the 15th century, crows were considered to be omens of death and messengers from the devil or evil powers.

5. A SCURRY OF SQUIRRELS

Jef Wodniack/iStock

Scurries are fairly unusual since squirrels are not pack animals by nature, so the more commonly used dray refers to a nest consisting of a mother squirrel and her young.

6. A WAKE OF VULTURES

For vultures, a wake specifically refers to a group feeding on a carcass. The less morbid terms kettle and committee are reserved for groups that are flying and resting in trees, respectively.

7. A BATTERY OF BARRACUDAS

Just one barracuda is intimidating, but a battery of them? Time to retreat!

8. A MUSTER OF STORKS

A muster can also be used for groups of peacocks/peafowl (though an ostentation of peacocks is much more illustrative).

9. A WALK OF SNAILS

Grotmarsel/iStock

Considering walk is one of the things a snail cannot do, this seems like an unusual choice. Perhaps the lesser-known (but still accepted) escargatoire would be more accurate.

10. A PARLIAMENT OF OWLS

tariq sulemani/iStock

It's unclear when this phrase was invented, with examples dating to the late 19th century. But its origin is likely an allusion to Chaucer's poem "The Parliament of Fowls," alongside the use of parliament as a collective noun for rooks.

11. AN AMBUSH OF TIGERS

guenterguni/iStock

Since tigers tend to be solitary creatures, a grouping of them would certainly feel like an ambush.

12. A COTERIE OF PRAIRIE DOGS

HenkBentlage/iStock

While full towns of prairie dogs are called colonies, the close-knit, individual family units are called coteries.

13. A MUTATION OF THRUSH

Stephen Barnes/iStock

An ancient and medieval belief that thrushes shed and regrew their legs each decade led to the collective term of a mutation of thrush.

14. A MEMORY OF ELEPHANTS

johan63/iStock

Sure, a herd of elephants is the more common collective, but a memory is also a recognized term. We're not sure why a pack of pachyderms didn't catch on though …

15. A SKULK OF FOXES

taviphoto/iStock

This term likely came about because mother foxes raise their young while burrowed underground.

16. A SCOLD OF JAYS

SHSPhotography/iStock

Jays also hang in bands and parties.

17. A COVEY OF QUAIL

SteveByland/iStock

While they can also group as a flock or a bevy, a covey of quail sounds much more poetic.

18. A HOVER OF TROUT

emmgunn/iStock

Since trout tend to swim in groups near the bottom of a lake or river, they likely look like they're hovering over the bed of the waterway. Alternately, it may come from an old term for an overhanging rock where fish—like trout—can hide.

19. A BALE OF TURTLES

dinozaver/iStock

Supposedly, a group of turtles who are cozy in their shells would look like a field of round or squarish hay bales.

20. A RHUMBA OF RATTLESNAKES

User10095428_393/iStock

Because, perhaps under circumstances that didn't involve a large number of snakes, that many rattles in one place would make you want to dance.

21. A CHARM OF HUMMINGBIRDS

Missing35mm/iStock

If just one hummingbird is charming, can you imagine how charming a whole group of them would be?

22. A BUSINESS OF FERRETS

JuergenBosse/iStock

The Book of Saint Albans gave ferrets the collective term busyness ("besynes"), which today has become "business."

23. A STUBBORNNESS OF RHINOCEROSES

CornelisNienaber_/iStock

They can collectively be called a crash of rhinos as well.

24. A PRICKLE OF PORCUPINES

Could this term be any more apt?

25. AN IMPLAUSIBILITY OF GNUS

ANDREYGUDKOV/iStock

Who knew?

26. AN UNKINDNESS OF RAVENS

MRaust/iStock

Ravens aren't exactly friendly fowl. They will often gang up on their prey or animals that enter their space. And because of the impression that they are an ominous presence, an unkindness of ravens can also be called a conspiracy.

27. A HAREM OF SEALS

evenfh/iStock

Specifically, when you have a group of females with a dominant male, it's a harem. If it's just some breeding seals hanging out, it's a rookery.

28. A MOB OF KANGAROOS

leelakajonkij/iStock

And just like in human mobs, there's usually a leader (a "boomer," or adult male) who is only in power for a short while before being challenged and defeated by a rival boomer.

29. A GAM OF WHALES

solarseven/iStock

Gam is a possible derivative of the word "gammon," meaning talk intended to deceive. Considering scientists have only just recently begun thinking they could decipher whale calls, we'd say the gam's gammon is pretty effective.

30. A POD OF PELICANS

They can also be called a squadron.

31. A GENERATION OF VIPERS

Mark Kostich/iStock

A group of snakes is generally a pit, nest, or den, but they're generally thought of as solitary creatures, so collective nouns for specific types of snakes are more fanciful. A "generation of vipers" likely originates from the King James translation of the Bible, in which Matthew 23:33 reads "Ye serpents, ye generation of vipers, how can ye escape the damnation of hell?"

32. A DESCENT OF WOODPECKERS

RT-Images/iStock

Woodpeckers are far more known for their wood-pecking style of foraging for food, but another method some have is to quickly dive-bomb anthills and termite mounds.

33. A RUN OF SALMON

A salmon run isn't just the mass migration of salmon up the river—a run of salmon is also the name of a grouping of the fish.

34. A KALEIDOSCOPE OF BUTTERFLIES

borchee/iStock

Groups of butterflies can also be called flutters.

35. A WISDOM OF WOMBATS

yellowsarah/iStock

Wombats have large brains and are incredibly playful, which is often viewed as a sign of intelligence.

36. A ROUT OF WOLVES

Cloudtail_the_Snow_Leopard/iStock

While pack is definitely the better-known term today, a very old term for wolves is rout, a word that ultimately came from the Middle French for company.

37. A SHIVER OF SHARKS

Janos/iStock

The term shiver applies a bit more to nervous humans when they see a large group of sharks, which is perhaps why the term has caught on in recent years.

38. A SCOURGE OF MOSQUITOES

Nataba/iStock

They're more commonly called a swarm, but a scourge sounds just as accurate.

39. A SLEUTH OF BEARS

Chilkoot/iStock

This isn't a reference to any detective work bears may or may not do—it's derived from the Old English word for sloth, meaning slow (and sloth itself is sometimes used as a collective noun as well). 

40. A GAZE OF RACCOONS

stanley45/iStock

The males are called boars and the females sows.

41. A SIEGE OF HERONS

joesayhello/iStock

When herons pick a new lake or river to rest at, the fish there would certainly feel under siege.

42. A FLAMBOYANCE OF FLAMINGOS

mantaphoto/iStock

Kudos to the creator of this perfect term.

43. A DESTRUCTION OF CATS

lilagri/iStock

A destruction refers specifically to a group of wild or feral cats. A group of domesticated cats is a clowder.

44. A FEVER OF STINGRAYS

EXTREME-PHOTOGRAPHER/iStock

At the very least, swimming with a fever of stingrays would surely cause your blood pressure to rise.

45. A SKEIN OF GEESE

Melbye/iStock

A skein is used specifically when geese (or other wild birds) are flying, while the alliterative gaggle is the term for grounded or domestic geese.

46. A BUNCH OF WORMS

Ben185/iStock

Not terribly creative, but when in doubt, just say "a bunch" of whatever.

47. AN EXALTATION OF LARKS

Supercaliphotolistic/iStock

An exaltation of larks also dates back to the 15th century Book of Saint Albans (which, because of its heraldry section, also happened to be the first book in England to be printed in color).

48. A FAMILY OF SARDINES

Donyanedomam/iStock

There are more than a dozen fish who can be labeled "sardine" in the supermarket. So in this case, family means a large grouping, rather than parents and children.

49. A BARREL OF MONKEYS

Gilitukha/iStock

Not just a game—it's a real term. Monkeys can also congregate as a carload, troop, or tribe.

50. A DAZZLE OF ZEBRAS

They're more commonly called a herd, but a zeal or dazzle of zebras has such a nice ring to it.

As you may already know, the corona in coronavirus has no relation to a certain refreshing beer often served with a slice of lime. Corōna means “crown” in Latin—and Spanish and Italian, too—and virologists chose it in 1968 to describe the group of viruses characterized by crown-like spikes that protrude from their surfaces.

So how do other viruses and diseases get their names? Based on the infographic below, created by Adam Aleksic for his website, The Etymology Nerd, there isn’t just one way. Some, like the coronavirus, are named for how they look under a microscope. The rota in rotavirus, for example, which means “wheel” in Latin, reflects the virus’s wheel-like appearance when viewed beneath an electron microscope.

Others are named after the locations where they were discovered or studied. In 1947, scientists named a newly identified mosquito-borne virus after Uganda’s Zika Forest. In 1977, Yale researchers investigating a string of pediatric arthritis cases in the town of Lyme, Connecticut, started referring to the illness as “Lyme arthritis.” Later, the name was modified to “Lyme disease” when scientists realized patients were exhibiting other symptoms, too.

Still others are characterized by the symptoms they cause. People with tetanus—from the Greek tetanos, for “tension”—usually experience muscle stiffness, and the skin of yellow fever sufferers often takes on a yellow tint due to jaundice.

Unsurprisingly, there's a lot of Latin in this infographic.
