it is so hard to narrow it down!! I'll think of general groups and then try to name standouts within those groups, to be concise...

I'll start with marsupials though because that's a much smaller list!!!

NUMBAT :D oh its like an incredible regional variant of a squirrel which eats only termites. So beautiful and so enchanting to see, such an interesting look for this niche...!
BILBIES :DDD YAAAY one of those creatures I could make up in my dreams. mmm another long tongue freak eating spiders... wonderful.

those would be the top 2, honorable mention to gliders and quoll (: I do like wallaby... but they can't beat numbat and bilby...

If I were to be super concise I'd probably say very vaguely, my fav animals are: parrots, mice, squirrels, moose, weasel...

I love parrots/cockatoos/psittaciformes a lot, overall... from broad ecological niches to individual species behaviors and rituals, I really feel a kinship...! standouts would be...... hyacinth macaw (SUCH gorgeous proportions, has that charming lumbering, slow thoughtful touchiness large macaws have... like grabs things with foots slowly...)... golden conure (such wonderful courtships)... and gang-gang cockatoo... (such a powerful beak, short and stubby)!

I love bovines, broadly, so much! I like the temperament of large ruminants, the slow calm energy contrasted by that heavy power, that confidence, and arrgh I love things with intense ruts... while small ruminants have the same qualities I love in rodents/rabbits... some standouts... bison, buffalo, many domestic breeds under that umbrella but distinctly barrosã cattle (the gender dimorphism of these, is PERFECT, I DON'T KNOW HOW ELSE TO PUT IT!!), black wildebeest (my god, fantasy gorgeous... mythical...). I love things like sable antelope, saiga, dikdik.. oooo dama gazelle sooo pretty!

Similar, I love moose very very much, another one of those "the perfect gender dimorphism" animals. I really love their courtship rituals... I wouldn't say cervines are super high in the grand scheme of ungulates for me, but their largest extant member is ideal....

Rodents are an obvious faaavorite of mine overall, it's hard to narrow down to specific species of mice and squirrel....! And JERBOA!!!! On the whole my preferences lean to arboreal squirrels (not big on ground squirrels, though I do love the common chipmunk!)... ugh I love guinea pigs too, such precious faces, and I watch a looot of guinea pig herd channels because I love their interpersonal dynamics! My favorite thing about social rodents are their relationships, expressions of friendships or fussiness. Of all the pets I've had, I think rats are the most special... they are just so wonderful, their hearts and minds are so complex. I never really felt like their 'owner', I felt like their weird friend (: That perfect amount of independence and interest, but able to get mad at you ahahaha. I like things that command and act out like rats can...

Lagomorph, especially haaares...!! I also like very large-eared domestic breeds like english lop...

VIVVERIDS!!! gennet, civet, linsang, binturong...! I don't know where to begin, the movement, and lifestyle, habitat... expressions... one of those perfect things..

random standout of SPRINGHARE!!... one of those very twitchy anxious things, very funny oddly square head, unique jaw, very interesting proportions. I'll always remember being spellbound learning about them as a child. Still pretty rare to find good videos of these... and almost nothing in the wild...!

MUSTELIDS are a huuge fav group overall, of predatory animals I think they are my favorite. One of the largest, the amazon river otter, gosh, one of my favs! Incredible proportions, I love how close to the front of the face their eyes are, their marbled throat markings... things that hunt in shallow water like mink I connect with a lot and loooove to watch videos of, when I play in shallow water I like to pretend to be a mink!! Stoats unbelievably tiny and fierce... Malayan weasel just so spellbinding, very recommend looking at...
martens (yellow-throated...pacific, American...) marbled polecats.

uuughh its never ending, *mongoose... ring-tailed mongoose...!! bushy-tailed and white-tailed...

Skunks...!!

if it's shaped like that, imagine I must logically love it I love this kind of weasely predator always! I feel foxes are relatively close to that ^^ foxes and tanuki are very up there, particularly grey foxes !!

uerggghhh I like horse behaviors and relationships SO much I watch a lot of videos about thissss, but distinctly I really love uhm, things like Kerry bog pony...! and other moor-dwelling breeds with unique traits suited to life in the moor.

CAPRA gooaaats, I like markhor and wild goats but my favorites are actually mostly domestic breeds like the Valais blackneck! Ah I adore the terrible harassment male goats bring a lot, just one of those abysmal rude boy animals I am weak too </3 going to ram everything and piss everywhere and be a major pest... </3 and I simply love low udders suchas this.

I like a lot of monkey and lemur lots...! marmoset like the golden-headed, black-tailed, goeldi's, gold-and-white... for lemurs its very hard to narrow it dooown but lemuroidea

anyway despite the list being this long I'm going to forget things. I actually like a lot of apes... overall I love to read and watch documentaries on such things.

I love herons, distinctly the blue heron... egret, distinctly cattle egret... arggh waterfowl, particularly Canadian geese (love their vocalizations). I feel like I could write an equally long answer just about birds which is like, RIP we don't need that... some other standouts, razorbill, barn owl, hornbills, aracari...

Sealife is like [dies] I can't do that it's too long BUT UHHH predatory tunicates, feather stars, sea lily....!! pulsing xenia coral.... sea lions... *steam coming off of me head* SHRIIIIIIMPS!!!! pipefish... brittle stars...
