Transgender Clownfish Controversy

On Monday and Tuesday, students of every grade were taught what the school called age-appropriate lessons about gender differences. Some lessons included all-girl geckos, a transgender clownfish, and boy snakes who act "girly" reports the San Francisco Chronicle.

"That's a lot of variation in nature," Gender Spectrum trainer, Joel Baum, told the students. "Evolution comes up with some pretty funny ways for animals to reproduce."

Principal Sara Stone said the lesson on gender differences was part of a larger effort to control bullying in the school, something parents supported last year.

However, after the lessons began, several parents felt discussion in the classroom was too much.
