Does the word wombat need to be capitalized?

Answer 1

only @ the beginning of a sentence.

{particularly if you are writing for school, business, etc & ect.}

come to think of it, beginning a sentence w/ the word wombat would be very rare in any circumstance.

Answer 2

Yes, "wombat" should be capitalized when used as the name of the animal species, as in "Southern Hairy-nosed Wombat."
