Back in 2007, Microsoft acquired Jellyfish.com, a comparative shopping engines.
Sometime recently, it seems Microsoft set up a 302 redirect from Jellyfish.com to Bing's search results for [jellyfish].
The interesting part is that this is a rare case where Google has indexed a link to Bing's search results.
The second result in Google for [jellyfish] is jellyfish.com:
When you click it, it does a 302 temporary redirect to http://www.bing.com/search?q=jellyfish&form=MSDTR1 and then shows search results on Bing for Jellyfish.
I am sure Google will remove the result soon from the search results but this is just a rare case of Google indexing a Bing search result page, because of a weird redirect.
