What is the difference between fish and seafood?

The difference between "fish" and "seafood" is primarily a matter of categorization. Here's a breakdown:

Fish:

* Specific: Refers to aquatic animals that have fins, gills, and usually scales.

* Scientific Classification: Belongs to the class "Pisces".

* Examples: Salmon, tuna, cod, catfish, trout.

Seafood:

* Broader: Encompasses all edible organisms that live in the ocean or other bodies of water.

* Includes: Fish, shellfish, crustaceans, mollusks, seaweed, etc.

* Examples: Shrimp, crab, lobster, clams, mussels, oysters, squid, octopus, seaweed.

Essentially, all fish are seafood, but not all seafood is fish.

Here's a simple analogy:

* Think of "fish" as a category of fruits like "apples".

* "Seafood" is the broader category "fruit".

Therefore, seafood is a wider term, encompassing all edible organisms from aquatic environments.
