Clownfish Dads Can Become Moms After Tragedy, Reveals Groundbreaking Nature Doc

In the months leading up to November 2025, a groundbreaking nature documentary titled "Second Nature: Gender and Sexuality in the Animal World" has been generating significant buzz. Directed by Drew Denny and narrated by Elliot Page, the film explores the remarkable diversity of gender and sexual behaviors observed across the animal kingdom.

One of the film's most intriguing revelations is the ability of clownfish to change sex from male to female. This fact, which may surprise many viewers, is used to pose a playful question: If Nemo's mother died in the Pixar film "Finding Nemo," could his father have simply become another mother? The documentary delves deeper into such biological realities, drawing on the research of evolutionary biologist Dr. Joan Roughgarden and other leading experts in the field.

Beyond clownfish, "Second Nature" examines a vast array of animal species, from reptiles and fish to insects, primates, and large cats. The film showcases the existence of diverse sexual behaviors and gender presentations, challenging the notion that such diversity is unique to humans. Elliot Page's narration helps to connect these scientific findings to broader societal discussions around gender and sexuality.

The journey to bring "Second Nature" to audiences has been a long one, spanning over a decade. Director Drew Denny's personal connection to the subject matter, having grown up as a young queer person in Texas, has fueled her determination to share these important stories. The film's production has faced some challenges, including concerns from potential funders that "there were more urgent issues than gay animals." However, Denny and her team have persevered, securing key funding from the Sundance Institute Documentary Film Program and Frameline's Completion Funds grant.

As "Second Nature" prepares for its upcoming release, the filmmakers are anticipating both praise and potential backlash. Denny acknowledges that the film's subject matter may face resistance, particularly in certain conservative or religious communities. However, she remains committed to sharing these scientific facts and challenging traditional narratives around gender and sexuality, both in the human and animal worlds.
