Filthy Animals is an ecology podcast for adults. Episodes may contain strong language and graphic descriptions of natural phenomena. A more detailed list of content warnings is included in each episode description.

Science educators will talk about the unusual adult activities of the natural world that we believe you need to know about. Every month, we’ll expose you to the latest research on all the filthy topics your high school science teacher was too embarrassed to talk about.

This podcast is produced by Grassland Groupies, and the music for this trailer is from Haydn London Trios, Hob. IV:1-3, accessed through MusOpen.

See you on April 25!
