Welcome to March Mammal Madness! This library guide is your official location for MMM tournament info and resources to help you fill out your bracket.
Since 2013, March Mammal Madness asks the question “Who Would Win?” when two animals encounter each other in an absurdly complex and wonderfully nerdy way… a simulated tournament within a structured game universe!!!
Participants fill out their brackets with their choices for the winners for each bout. Scoring occurs at the end of the tournament, points allocated as follows:
Nerd Alert: This sequence of numbers may seem familiar! The scoring system used by MMM is the Fibonacci sequence related to the Golden Ratio... and found so often in Nature!
We can only suggest the following for maximal fun and learning. Print out the bracket, predict who will win in each of the match-ups in round one, then round two, and so on and so forth, all the way out to your prediction who wins the championship! Get your friends, colleagues or family to play. Post brackets on wall prominently. Follow along in real time with battle play by plays on Bluesky by following @mmmletsgo.bsky.social and #2025MMM on scheduled bout nights. If social media isn't your thing, check this library guide for updates a couple of hours after the bouts conclude for the night (or the next morning).
The battles are not always “nature, red in tooth and claw.” Sometimes the winner "wins" by displacing the other at a feeding location, sometimes a powerful animal doesn't attack because it is not motivated to- in 2014 for the “Who in the What Now?” Division, dhole lost to a binturong because the night before dhole had gorged on babirusa and the gut passage time of wild canids is 24-48 hours. This meant that the dhole was still full from the night before and unwilling to take the risks of tangling with the binturong. Even a small claw cut or bite wound can get infected and lots of times an animal will back down rather than take a risk for little potential benefit.
Typically, battles are one on one. However, in 2017 there was a team: the Neanderthal Hunting Party, which was a small group of hunters working together with Neanderthal technology. In general, assume that the combatants represent the most prime-aged, healthy and strong specimen of that species. Also, just as in nature, there can occasionally be scientifically-grounded outside interference.
Not necessarily! Real fans don’t abandon their favorite animals just because they are pathetic at this kind of battle (although hopefully well-suited to their particular environmental niche). People will clown you if your bracket is too conservative by always picking the better-ranked combatant. Also the rankings are not infallible and there are upsets in nature too. Upsets are what make March Mammal Madness exciting.
Although originally the tournament only featured mammals, for many years many animals and sometimes plants, fungi, lichen and bacteria are invited to the big show. Most importantly, all species are awesome, so we’ve expanded the combatant line-up and but kept the name for tradition.
MMM is indeed inspired by, but in no way affiliated with or representing, the NCAA College Basketball March Madness Championship Tournament. But we’re pretty sure the term March madness, at least in part, comes from the long-time English idiom about fast-paced and sometimes unpredictable animal battles.
Have we got you covered in our MMM scholarship and data section!
Most probably not. If you have a deep affinity for an animal, but your identity means you are culturally appropriating when you use the term, there are many options. We suggest: "inner animal", "anima", "emblem", or "animal quiddity/quidditas." #WordNerds. And please be thoughtful about those reaction gifs too.
Our friends at the Denver Museum of Nature & Science are excited for 2024 MMM!
The ASU Library acknowledges the twenty-three Native Nations that have inhabited this land for centuries. Arizona State University's four campuses are located in the Salt River Valley on ancestral territories of Indigenous peoples, including the Akimel O’odham (Pima) and Pee Posh (Maricopa) Indian Communities, whose care and keeping of these lands allows us to be here today. ASU Library acknowledges the sovereignty of these nations and seeks to foster an environment of success and possibility for Native American students and patrons. We are advocates for the incorporation of Indigenous knowledge systems and research methodologies within contemporary library practice. ASU Library welcomes members of the Akimel O’odham and Pee Posh, and all Native nations to the Library.
