The plural form of "fish" is most commonly fish itself, especially when referring to multiple individual fish of the same species. However, fishes is also an acceptable plural, typically used when discussing different species of fish.
When you refer to a group of fish, even if there's more than one, the word often remains unchanged. For instance, if you have a single aquatic creature, it's "one fish," and if you have several of the same type, you still say "two fish," "three fish," and so on. This is because "fish" functions as an irregular plural, similar to words like "sheep" or "deer."
Understanding the Usage: 'Fish' vs. 'Fishes'
The distinction between using "fish" and "fishes" depends largely on context:
-
Use 'Fish' for multiple individuals of the same species:
- This is the most common usage.
- It treats "fish" as a collective noun or an invariant plural.
- Example: "We caught ten fish in the lake today."
- Example: "My aquarium has many colorful fish."
-
Use 'Fishes' when referring to multiple species:
- "Fishes" emphasizes the variety or different types of fish.
- It's often used in scientific or academic contexts to highlight biodiversity.
- Example: "The ocean is home to thousands of different fishes."
- Example: "The marine biologist studied the various fishes found in the coral reef."
Practical Examples
Let's look at some scenarios to clarify:
- Scenario 1: Same Species
- If you see a school of tuna, you would say, "Look at all those fish!" (Referring to many individual tuna).
- Incorrect: "Look at all those fishes!"
- Scenario 2: Different Species
- If a documentary is showcasing the diverse marine life, it might say, "The Galapagos Islands boast an incredible array of fishes, from sharks to seahorses." (Referring to various kinds of fish).
- Less common but acceptable: "The Galapagos Islands boast an incredible array of fish..."
