Phil Rice answered on 18 Mar 2013:
Hi Coraline; good question. Animals reproduce asexually or sexually (like us). Sexual reproduction is the most successful way because it shuffles genes from both parents which provides an excellent defence against infectious diseases. It generate genetic heterogeneity which evolution feeds on when faced with selection pressures.

Phil’s exactly right there, in most animals it’s pretty similar to us. Things get a little bit different when you’re talking about fungi or plants.
For a fun fact, bed bugs don’t have a vagina so the male actually drills into them to fertilise their eggs!

Thanks, it’s a little bit terrifying. I think I found it out from green porno – there’s a lady who acts out strange ways that sex happens in different animals. http://www.youtube.com/watch?v=MakIB_IJnu0 I’d also check out ducks – that’s pretty crazy too!
