How Do Animals Express Emotions?

I found out about animal and animal behavior was fascinating. I first started with a series of short film, comical film for Sand Dance Channel called Green Corner. And they were incredibly successful. So then I made a second series I tried as he called it seduced me - another one about motherhood because biodiversity exists. In this one I talk about expression of emotion in animal and in humans but also my experience as an actress to fakingly portray them in films. It connects all my different interests.
