Female animalization is the depiction of women as animals, or as hybrid human-animals. It’s in fact a subgenre of female objectification, which is itself a subgenre of dehumanization (see also here). Depicting a woman as an animal means taking away her human characteristics and can lead to gender discrimination. It’s easier to deny the rights of an animal than the rights of an individual human being.

Some time ago, this image was the first to appear when people googled for images of Michelle Obama. Because of this Google issued this statement:

Search engines are a reflection of the content and information that is available on the Internet. A site’s ranking in Google’s search results relies heavily on computer algorithms using thousands of factors to calculate a page’s relevance to a given query.
The beliefs and preferences of those who work at Google, as well as the opinions of the general public, do not determine or impact our search results. Individual citizens and public interest groups do periodically urge us to remove particular links or otherwise adjust search results. Although Google reserves the right to address such requests individually, Google views the integrity of our search results as an extremely important priority. Accordingly, we do not remove a page from our search results simply because its content is unpopular or because we receive complaints concerning it. We will, however, remove pages from our results if we believe the page (or its site) violates our Webmaster Guidelines, if we believe we are required to do so by law, or at the request of the webmaster who is responsible for the page.

At this point, I should probably mention that men as well can be animalized, and have been to great political effect throughout history. Here’s one example:
