Why is a female whale called cow?

Female whales are not typically called "cow." While the term "cow" is sometimes used for female mammals in general, it's not a common or accurate term for female whales.

Here's why:

* Scientific Classification: Whales are marine mammals, not bovines (the family that includes cows). They have different evolutionary histories and physical characteristics.

* Common Usage: The terms "female whale" or "mother whale" are more commonly used in scientific and general contexts.

* Specificity: Using more specific terms like "female humpback whale" or "mother orca" helps to identify the particular species and role of the animal.

So, while you might hear "cow" used informally to refer to a female whale, it's not a scientifically accurate or commonly accepted term.
