NEXT UP: #3 Crabeater Seal Vs. #6 Jaguarundi!!! #2018MMM
This battle was written by @Drew_Lab. Josh is in the UK right now & he was at Darwin's House today. How cool was that? #2018MMM
The Crabeater Seal skated into R2 after lightly munching on the surprisingly aptly named Edible Dormouse, while the Jaguarundi defeated the Desman #2018MMM
As the Crabeater Seal is a higher seed, tonight's battle will take place on the pack ice of the Southern Ocean #2018MMM
The Crabeater Seals' global population is estimated at 15 million, making it the second most populace large mammal species other than humans antarctica.gov.au/about-antarcti… #2018MMM
Unlike other seals, Crabeaters spend most of their life on pack ice: free floating ice that surrounds the Antarctic continent arkive.org/crabeater-seal… #2018MMM
Side bar, Josh is currently in the UK looking at old ship records to understand the historical ecology of sea ice dependent species like the Crabeater Seal #2018MMM
Tonight's battle takes place on the ice as the Crabeater Seal has retreated from the water to rest and digest #2018MMM
The Jaguarundi, while not a fan of the cold, is at least on solid ground..well ice #2018MMM
Big-cat researcher Michael Tewes (Texas A&M Kingsville @JavelinaNation) has done a good bit of research on Jaguarundis, esp. in relation to conservation onlinelibrary.wiley.com/doi/full/10.10… #ActualLivingScientist #2018MMM
The Jaguarundi smells the Crabeater Seal, redolent of sea breeze, salt air, and... crustacean breath #Krillmonger #2018MMM
The Crabeater Seal perks up. There usually are no predators on the pack ice; this is a place of safety! The Seal is unaccustomed to danger not coming from the sea #2018MMM
The Jaguarundi hunkers down low and adopts its normal stalking motion. However, as the background cover is bright white, despite its best efforts it is fairly obvious. Sort of like the picture below #2018MMM
Crabeater Seal undulates over to investigate, baring its teeth #2018MMM
The Jaguarundi pounces forward hoping to use what little element of surprise it has remaining. Jaguarundi sinks its 9.7mm canines into the Crabeater Seal while clinging with his claws academic.oup.com/mspecies/artic… #2018MMM
However the Seal's blubber is up to 5 cm thick (sciencedirect.com/science/articl…) so the bite does little damage #2018MMM
The Crabeater Seal thrashes to dislodge the little kitteh! #2018MMM
And rolls over. 600+ lbs of pinniped bulk are crushing down on the Jaguarundi! #2018MMM
Jaguarundi's last breath escapes his lungs as he fails to escape Crabeater Seal #2018MMM
CRABEATER SEAL SQUASHES JAGUARUNDI #2018MMM

UP FIRST TONIGHT: everyone's favorite river horse, the 1-seeded PYGMY HIPPO Hexaprotodon (formally Choeropsis) liberiensis, vs. the scrappy 4-seeded brush wolf, COYOTE Canis latrans! #2018MMM
Many minds came together to bring you tonight's first battle, so a quick hat-tip to @AnneWHilborn, @PKurnath, @TCastanea, & @tinkeringprim8. Seriously, the #teamwork has been amazing #Monstars #2018MMM

UP NEXT: #3 seed Berlin Boar (Sus scrofa) vs #7 seed Porcupine (Erethizon dorsatum) #2018MMM
The top-ranked competitor still has homefield advantage, so this Urban Jungle battle takes place in Berlin, Germany. Berlin Board & Porcupine don't have a lot in common; they last shared a common ancestor ~96 mya (timetree.org) #2018MMM
Did you know what "Porcupine" is Latin for "Quill Pig"? Follow #ActualLivingScientist @porcupinedoc for some more amazing porcupine facts #2018MMM

NEXT UP: 7th seeded Porcupine (Erethizon dorsatum) vs 10th seeded Delhi Rhesus (aka, Rhesus Monkey or Rhesus Macaque; Macaca mulatta) #2018MMM
Erethizon dorsatum are the 2nd largest rodents in North America (1st place goes to beavers), weighing anywhere between 5-14 kg (23-64 stoats #stoatsasmeasurement) #2018MMM
When we think porcupines, we think quills, right? Quills & spines have evolved multiple, independent times across the mammal tree of life as a defense strategy & are excellent examples of convergent #evolution (see the hedgehog battle) (animaldiversity.org/collections/sp…) #2018MMM
