Here's why:
* Different fish have different structures: Fish are incredibly diverse. Some have fins, others have scales, and others have unique features like venomous spines.
* Defining "body part" is subjective: Do we count individual scales as body parts? Do we count the bones in its skull? Or only major organs like the heart and gills?
Instead of focusing on a number, let's look at the general body parts of a fish:
* Head: Includes the mouth, eyes, gills, and brain.
* Trunk: The main body section, containing the internal organs.
* Tail: The rear portion of the body used for propulsion.
* Fins: Used for steering, balance, and propulsion.
* Scales: Protect the fish's skin (some fish lack scales).
So, while we can't give you a specific number, we can understand the major parts that make up a fish's body!
