Where do intext citations go in a direct quote mla?

Example:
One reason why the zoo needs more exotic animals is for income increase and more tourist attraction. People love animals. People love animals they've never seen before even more.(J.Walker, pg.56)

Hope this helps:) If you're doing a research essay, don't forget MLA format in your works cited page too, I recommend EasyBib.com to convert a simple link into mla formated citations on your works cited page. :) Also you don't have to put in bold the direct quote, just put in parethesis the author and page number.
