    Koala Chlamydia

    · Filthy Animals

    Content Warning: graphic descriptions of STIs, death, some sprinkling of thinking too much about how much of a horror bodies are.

    Koala's are well known for being disease ridden (at least in our circles) so lets talk about it. Chlamydia is highly contagious and deadly in koalas as well as birds, cows, and many other animals. This is a trip down sex education memory lane and details the horrible death that is untreated STIs.

    Turns out lots of animals just wait around till maturity and then turn into horny little guys. The genus Antechinus is no exception as males will mate over and over until exhaustion.

    Filthy Animals Premiers April 25

    · Filthy Animals

    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!
