Aardvarks are notable for their long nose, wider at the far end, their squared-off head, a tapering tail, & very impressive ears. The body is massive with really thick skin & they have very muscular limbs ending in thick-nailed toesies. (Ratzloff 2011) #2025MMM

The aardvark's genetic structure is influenced by climate! Research shows that arid regions limit gene flow among aardvark pops, leading to genetic differentiation, suggesting that climate-associated adaptations play a key role in aardvark evolution! onlinelibrary.wiley.com/doi/10.1111/… #2025MMM

Southern brown bandicoots are a small marsupials are 40% tail… or they would be if they didn't routinely lose chunks of tail (or all of it) from male combat. Their short, coarse fur ranges from black, grey, brown & golden yellow, with extremely small, rounded ears. #Bandicoot #bandiCUTE #2025MMM

Genetics shows how fragmenting landscapes puts species at risk. Genetic analysis of 15 microsats shows Bandicoots living in 14 forest fragments tend to stay close to home. Strategically placed habitat corridors could help, though! #2025MMM link.springer.com/article/10.1…

Tonight in the Nama-Karoo in western South Africa, an Aardvark has dug up… an aardvark cucumber! Usually eating insects, this cucumber is the only fruit aardvarks eat & Aardvark cucumbers rely on aardvarks to disperse their seeds (Shoshani et al 1988) #TagTeam #2018MMM #2025MMM

Marc Kissel (@marckissel.bsky.social) 2025-03-18T01:12:07.511Z

Meanwhile, in Western Australia, Yalgorup National Park Bandicoot is poking nose into the ground, digging just 1 of 45 foraging pits he makes a day searching for invertebrates, tubers, seeds & fungi. Manipulating soil for food (biopedturbation) helps soil turnover (Valentine et al. 2012) #2025MMM

Marc Kissel (@marckissel.bsky.social) 2025-03-18T01:13:52.866Z

Bandicoot hears grunting & squeaking from nearby, indicating another bandicoot is close! He squeaks back, preparing for battle, readying to “strike with its claws & removing patches of hair." Scooting forward… #MMMagic translocates Bandicoot to the Karoo… (Driessen & Rose 2015) #2025MMM

Marc Kissel (@marckissel.bsky.social) 2025-03-18T01:14:41.203Z

Bandicoot sees the big rounded mammal nearby. Clouds cover the full moon's light, shadowing the desert landscape, & Bandicoot mistakes Aardvark for a simple wombat doing wombat deeds. Bandicoot begins to forage for termites #2025MMM

Marc Kissel (@marckissel.bsky.social) 2025-03-18T01:15:24.112Z

Aardvark slakes his thirst- the cucumber is a key source of water in this landscape- but still seeking some protein… Aardvark's long snoot starts sniffing for termite #2025MMM

Marc Kissel (@marckissel.bsky.social) 2025-03-18T01:16:20.592Z

Bandicoot, still certain the nearby stranger is a wombat, seems unconcerned… but the two are about to converge at a termite mound #2025MMM

Marc Kissel (@marckissel.bsky.social) 2025-03-18T01:17:11.399Z

The clouds shift, casting moonlight onto the scene… Bandicoot gazes in horror upon the strange Aardvark… and flees from the stranger in the night… beyond the field of battle! #2025MMM

Alyson Brokaw, PhD (@alybatgirl.bsky.social) 2025-03-18T01:22:05.850Z

The mouse-deer is a small, rabbit-sized ungulate weighing between 5 to 8 kg (or ~30 stoats, #StoatsAsMeasurement). A rounded body perched on pencil-thin legs, male mouse-deer have neither horns nor antlers, but small, tusk-like canines #2025MMM

Greater Mouse Deer on Thai mainland today survive only in captivity. Genetics shows inbreeding/reduced ability to adapt. Are they doomed? Nope! Breeding program = more mouse deer in captivity. Now, urgent habitat improvement needed to support reintroduction #2025MMM http://www.mdpi.com/2071-1050/15…

Nate Upham (@n8upham.bsky.social) 2025-03-18T01:23:27.480Z

With a rounded body and thick, strong legs, the paca is a large forest rodent (6 -12 kg, or ~50 stoats). They have sleek chocolate-brown fur with several rows of white spots and broad cheekbones (Perez 1992) #2025MMM

The Lowland Paca has a one-of-a-kind genetic blueprint that helps confirm where it fits in the rodent family tree! Li et al. (2023) recently sequenced its full mitochondrial DNA, giving us a clearer picture of its evolution. #2025MMM http://www.tandfonline.com/doi/10.1080/…

Nate Upham (@n8upham.bsky.social) 2025-03-18T01:26:53.329Z

Moonlight shimmers across the waters of the Brazilian Pantanal, and the Paca is at the opening of her den. She emits a low, grunt (Sabatini et al 2001) and waits for her young precocious pup to follow her out for a night of foraging. #2025MMM

Alyson Brokaw, PhD (@alybatgirl.bsky.social) 2025-03-18T01:30:00.277Z

On the edge of a different river in Sumatra, the Mouse-deer is moving through the dense underbrush at the edge of his territory. He stop and rubs his jaw along a nearby tree, marking it using the gland under his chin (Ralls et al 1975). #2025MMM

Alyson Brokaw, PhD (@alybatgirl.bsky.social) 2025-03-18T01:30:29.174Z

Satisfied with his efforts, Mouse-deer turns to continue his patrol of his territory, but instead finds himself staring at a hole and the face of an unfamiliar creature. He freezes, one of his front foot slightly raised. #2025MMM

Alyson Brokaw, PhD (@alybatgirl.bsky.social) 2025-03-18T01:31:10.872Z

Paca stares back at the intruding Mouse-deer. GRROOOANNN. A low grumble as Paca grinds her teeth loudly in agitation as the fur along her spine rises. #2025MMM

Alyson Brokaw, PhD (@alybatgirl.bsky.social) 2025-03-18T01:31:40.721Z

Thump. Thump. Thump. Mouse-deer stamps his front feet in an increasing rhythm. Maybe this slightly mouse-deer shaped animal will just go away? #2025MMM

Alyson Brokaw, PhD (@alybatgirl.bsky.social) 2025-03-18T01:32:10.643Z

Paca emits a series of loud grunts and positions her body to shield her pup. With a lurch, she lunges forward, teeth bared… #2025MMM

Alyson Brokaw, PhD (@alybatgirl.bsky.social) 2025-03-18T01:32:27.333Z

And bites down hard on the nose of the Mouse-deer. Startled, Mouse-deer turns and sprints away, leaving Paca still at the entrance to her burrow. #2025MMM

Just look at the Greater Mouse Deer's lil' tongue there! Practically drooling at the potential for new wild habitat after its reintroduction becomes a reality. But until humans can get out of the way, that drool will mostly be applied to captive breeding. #RIP #2025MMM http://www.mdpi.com/2071-1050/15…

With an elgonated nose, pale eye and nose 'mask', and long, slender tail that equals their body length, Coatis look a bit like a stretched out raccoon (to whom they are related, Gompper 1995) #2025MMM

The Fig-eating Bat is nocturnal but has a functional OPN1SW color vision gene, unlike many of its close relatives among noctilionoid bats. It's not just gene loss in this lineage—changes in gene expession (usage) play a role as well #2025MMM elifesciences.org/articles/37412

Over on the Caribbean island of Cuba, our Bat stretches a wing and scratches at her shoulder, just below the patch of pure white fur. A warm wind rustles across the surface of her green leaf tent when…WHOOSH! #2025MMM

Bat's nose leaf twitches rapidly as she echolocates, getting her bearings. Though the forest is not that differnet from home, she does not like moonlight… (Zeppelini et al 2019). #2025MMM

and despite the name, Fig-Eating Bat doesn't particularly like FIGS. Analyses of fecal samples reveal this bat consumes Cercropia seeds, non-native rose-apple (Syzgium) & insects. (Mancina and Garcia-Rivera 2000) #2025MMM

Eastern Grey Kangaroos are <brace yourselves for shock> a mostly grey-furred macropod. In terms of convergent evolution, they are the marsupial equivalent of a deer: eating grass, widely distributed, living in many different habitats. (Joo 2004) #2025MMM
