Welcome to Creature Feature, production of IHeartRadio.

I'm your host of Many Parasites, Katie Golden.

I studied psychology and evolutionary biology, and today on the show, it's a listener

questions episode.

I answer your questions that you send to me at creaturefeaturepod at gmail.com.

If you have any questions about evolutionary biology, your pets, animal behavior, I will do my best to answer them.

I love these questions.

They often make me do a little bit of homework, do some research going up on my

evolutionary biology, and so I love them. And I really appreciate you guys writing in. Let's get right

into the first listener question. Hi, Katie. I absolutely love learning and I love animals.

So when I found your podcast, I was ecstatic.

I'm constantly annoying my friends and family with the fascinating facts I've learned while listening to your podcast.

I am still working my way through your podcast, so I'm not sure if you've covered this topic yet,

but I am so fascinated with animals that have evolved to change their sex.

I know there are fish, clownfish, and Asian sheep's head

wrasse that can do it. And also a lizard in Madagascar, I think that lays fertilized eggs

limiting the need to mate with a male. It's just so amazing how nature can just evolve like that

in order to survive. Are there other animals besides those two, fish and that lizard that

have evolved in this way? I would love to hear more from a biologist's perspective on this topic.

Also, if this is an episode already, which is it? Which one is it? I want to hear all the things.

Thank you again for such a great podcast and can't wait to hear more.

This is Chelsea from Cole Valley, Illinois. Hi, Chelsea. Thank you so much for your question.
