Questions & Answers

Q: How do clownfish find their lost children in real life?

While Finding Nemo showed the parents searching for their lost child, in reality, clownfish can find their lost children through scent and sound cues.

Q: Why do clownfish live within anemones?

Clownfish live within anemones to gain protection from predators, as they produce a mucous layer that makes the anemone think they are part of it and not sting them.

Q: How do clownfish reproduce?

Clownfish lay eggs every few weeks, and the male takes care of them until they hatch, protecting them from potential threats.

Q: Why do clownfish change their gender?

If the dominant female clownfish dies, the male clownfish can turn into a female to maintain the balance in the group and continue reproducing.

Summary & Key Takeaways

• The movie Finding Nemo portrays clownfish inaccurately as it doesn't show that mommy and daddy clownfish can actually find their lost children in real life.

• Clownfish have a unique symbiotic relationship with anemones, using them for protection and not getting stung by their venom.

• Clownfish are sequential hermaphrodites, meaning they can change their gender from male to female if the dominant female dies.
