What is a Group of Shrimp Called? The Fascinating Collective Nouns for These Crustaceans

Shrimp are ubiquitous creatures that live in oceans, seas, lakes and rivers across the world They are an important part of many ecosystems and also provide sustenance for humans as a popular seafood But when we see a group of shrimp together, whether in the wild or in an aquarium or farm, what exactly do we call them collectively? This fascinating question has several potential answers rooted in history, science and aquaculture.

The Origin of Collective Nouns for Animals

Collective nouns for groups of animals have been around for centuries, with many of them originating from medieval hunting terms. The practice of using special names for animal groups evolved as a unique part of the language of hunters in the Middle Ages. These fanciful terms, known as “terms of venery,” helped hunters identify their prey and added flair to the hunt.

Some examples include a “murder” of crows a “crash” of rhinos, and a “business” of ferrets. Over time collective animal names expanded beyond hunting terminology to include many more species, including ones not hunted like domestic animals and invertebrates. This enriched the English language with colorful and poetic ways to describe animal assemblages.

The Challenge of Naming Shrimp Groups

Coming up with widely-accepted collective terms for certain animals like crows or rhinos is straightforward enough. But what about a species as abundant and ubiquitous as shrimp? With over 2,000 species spanning aquatic ecosystems worldwide, settling on standard group names is difficult. The lack of consensus reflects the diversity of shrimp and their niche habitats.

Additionally, shrimp are not as well-studied as many vertebrate species. They do not garner as much public fascination either, being small invertebrates. All this means shrimp lack definitive collective nouns like “pride” for lions or “murder” for crows. But there are still some common ways to describe shrimp groups, depending on context.

General Ways to Describe Shrimp Groups

If you spot a group of shrimp and don’t know what species they are, you have several collective noun options:

• Shoal
• Swarm
• School
• Colony
• Brood

Of these, “shoal” is the most generally applicable term for shrimp. It derives from the Old English “scol” for “multitude” or “crowd.” “Shoal” can describe any group of fish or aquatic animals clustered together, making it perfect for mixed or unknown shrimp species.

Other collective nouns like “swarm,” “school,” or “colony” also work for generic shrimp assemblages. “Brood” is more specific, denoting a group of recently hatched shrimp from a single mother.

Species-Specific Shrimp Group Names

For identifiable shrimp species, certain collective nouns are more suitable:

• Krill – Shoal, swarm
• Mantis shrimp – Stalk
• Brine shrimp – Colony, cloud
• Ghost shrimp – Cluster, cloud
• Crayfish – Trap

Krill, for example, form enormous shoals that may contain over 10,000 shrimp per cubic meter in certain areas of the oceans. The giant shoals of these tiny crustaceans are crucial food sources for whales, penguins and other marine life.

Mantis shrimp are solitary creatures that only come together briefly to mate. When they do, the assemblage is called a “stalk.” Ghost shrimp often gather in loose “clouds” across tidal flats and wetlands, while burrowing crayfish emerge in periodic communal “traps.”

Why “Clutch” is Used for Shrimp Broods

When it comes to a group of shrimp recently hatched from eggs, “clutch” is the most accurate term. Shrimp carry their fertilized eggs attached to their swimmerets until they hatch into tiny larvae.

“Clutch” comes from the fact that female shrimp physically clutch the egg mass, protecting the brood pouch until hatching. This term is used across scientific literature when discussing reproduction and larvae in shrimp and other crustaceans. Examples include:

“The female shrimp released a clutch of over 2,000 larvae.”

“After the clutch hatches, shrimp larvae will enter a planktonic stage lasting several weeks.”

So if you are specifically talking about a recent shrimp hatching in aquaculture or the wild, “clutch” is the standard way to describe the assemblage.

Reasons for Multiple Shrimp Group Names

The variety of names used for shrimp groups reflects the diversity of shrimp themselves. With over 2,000 species occupying diverse aquatic habitats worldwide, a single collective term does not fit.

Additionally, shrimp terminology caters to different contexts. For example, scientists studying reproduction may use “clutch,” while marine biologists observing shoaling behaviors out at sea would use “shoal.” Shrimp farmers and aquaculturists would use industry-specific terms like “broodstock” for breeding shrimp.

Naming shrimp groups is also challenged by their small size and lack of research compared to mammals, birds, and fish. Without an extensive literary history like lions or crows, shrimp collective nouns are not as defined. The multiplicity of terms for assembled shrimp thus underscores their prevalence across the planet in many ecologies and roles.

Part of what makes animal collective nouns so fascinating is their blend of science, culture and wordplay. While no consensus exists for shrimp, some patterns do emerge. “Shoal” suits any gathering where species is unknown. Industry terms like “broodstock” are used in aquaculture, while “clutch” denotes a recently hatched group. “Swarm,” “school,” or “colony” can also apply generically.

So next time you come across a crowd of these captivating crustaceans, you have poetic license to use a variety of apt descriptors. Just as shrimp thrive across diverse aquatic ecosystems, so too do their collective names reflect this versatility. The nuances of shrimp group terminology ultimately trace back to the animals’ biological success across the waters of the world.
