About Filthy Animals
Filthy Animals is a sex, drugs, and ecology podcast for grown-ups. Every month, science educators discuss the unusual adult activities of the natural world that your high school science teacher was too embarrassed to talk about. This podcast features hosts Rachel Roth, Nicole Brown, and Allan Saylor of Kansas-based nonprofit Grassland Groupies.

S2E8 - A Truly Rotten Episode
Content Warning: heavy discussion of death, decomposition, and impolite body functions. I believe it was Imhotep in 1999's The Mummy who said "Death is only the beginning...", and he was right! Not in the sense of returning from the realm of the dead to fight Brendan Fraser, but in the sense that death turns an organism's mortal shell into a entirely new sort of ecosystem. In this grisly-yet-surprisingly-positive episode, Nicole walks us through the science of decomposition, how it's applied to everything from solving crimes to food freshness, and why we couldn't live in a world without decay.

S2E6 - A Game of Cucks
Content Warning: none In this month's Filthy Animals, Rachel tests the strength of monogamous bonds in the animal kingdom by seeing what the data says about their infidelity. As it turns out, even in species where pair bonds are key to the social survival of the animals, reckless passion can play a big role in their breeding systems. Our host graciously brings us examples ranging from the expected (cuckoos, the species that gives us the word "cuckold") to the obscure (carrion beetles, whose relationship drama plays out in carcasses the world over).

S2E5 - The Dog That Never Died
Content Warning: Discussion of cancer and related illnesses Cancer is scary. A transmissible, STI-based cancer is even scarier.

S2E1 - RANKED: Love (The Dangerous and The Dumb)
Content Warning: cannibalism, suicide, coercive/violent sexual behavior, death during pregnancy, partner death, drowning, necrophilia (start the episode at 36:12 to avoid our discussion of all of the above, which are discussed in the context of "most dangerous courtship behaviors". we promise, it gets much sillier after that!) Filthy Animals is back! We open Season 2 with some very important data-driven nonsense to settle some burning questions about the world of animal courtship. TO WIT: Which animals are mating in the most dangerous way possible, AND who is doing it the most obnoxiously? Danger and stupidity abound. Let the great debate begin!

S1E6 - Let's Talk About (Not) Sex
Content Warning: References to sex and nonviable pregnancies. Spending every moment of waking life trying to get laid has its downsides, and for some organisms, the business of reproduction is just too much of a hassle. So why bother with mating at all? If you want something done right, sometimes you just have to do it yourself. In this episode, Nicole runs down the fascinating asexual strategies of plants and animals, from self-printing bananas to all-female lizards to condor virgin birth.

Koala Chlamydia
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.

Filthy Animals Premiers April 25
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 (https://www.grasslandgroupies.org/), and the music for this trailer is from Haydn London Trios, Hob. IV:1-3, accessed through MusOpen (https://musopen.org/). See you on April 25!
