Animals whose name sounds like a letter that doesn't appear in its name

EWES

Think of female sheep and the vowel that’s missing from their name—it’s the one you’d say if you were spelling out the word “you.”

The clue plays on the word "ewes," which sounds exactly like the letter "U." The twist is that the letter U doesn’t actually appear in the word "ewes," making it a clever match for the description. Ewes are female sheep, so the answer fits both the animal and the letter-based wordplay.
