Is this wild rabbit sick ?

Went cycling along a canal today. I went past it on my bike and it was nestled between the foliage. It didn't move which is unusual behaviour for a wild rabbit when cycling past it very fast. Around half an hour later, on my way back, I cycled past it again. This time it started hopping as it saw me and then it sat still and closed its eyes! I'm surprised it didn't run away. It was in the same place. It was very small, not sure if it's sick or if it was some sort of defence thing.

Could Gorillas and Giant Pandas be described as ecologically convergent?

I don't really know if this makes much sense but I'm kind of curious if it could be said that Gorillas and Panda bears are sort of similar ecologically in being reasonably large, browsing animals that make particular use of their grasping forelimbs in manipulating and pulling selected plants into their mouths, often in a similar position while eating. They seem quite different from other herbivores but I don't really know enough about the specifics of their behaviour and adaptations to know whether or not they are very similar or if I'm just going by surface level interpretation since they both seem to spend most of the time sitting around munching on plants they pull down and hold with their forelimbs.

One of the other reasons I wonder about this is because it sort of seems that there was a recurring ecological role like this among a wide variety of extinct animals including Therizinosaurs, Grounds Sloths, Chalicotheres and possibly some other dinosaurs like Plateosaurus or other mammals like Palorchestes, and I'm wondering if Gorillas and Pandas can be seen as the closest modern analogues to these kinds of animals.

🔥This is a Red ruffed lemur. In the wild, this animal lives exclusively on the island of Madagascar, specifically in the primary rainforests of the Masoala Peninsula in the northeastern part of the country

Why the firefly is much more innovative than any lamp

The firefly converts 98 percent of the energy it consumes into light—whereas the efficiency of modern LED lights is only 50 percent. Interesting text!

suggest me abilities to give my animals for my game :)

(once again not stating the game name or platform for respect to no advertising rule)

you may or may not have seen my other post, but to run through it, I’m currently making a silly animal game where you can choose between a roster of lesser known species that members of the community decided to include in the game, and fight each other to the death :D (not encouraging irl animal fights)

The animal suggestions are still going so you can still submit animals you’d like to see but I was also wanting to ask the community again for any suggestions for potential abilities and attacks that I WILL do what I can to implement them in the game, and if you can you can even include concept drawings in your comment so we further know what to do :>

Mods, this isn’t a karma farm it’s just something to bring the already fun community together to make it even more fun

as always, if youre gonna suggest animals you’d gotta follow these rules:

No elephants, common hippos or giraffes
No fully aquatics
No animals that went extinct more than 2000 years ago
No cryptids
No domestics
No grey night herons (oh no)

Help identifying jaw bone

Found outside a pet store, central coast CA. I thought it might have been a cow or a pig, but someone was telling me they thought it was a dog. It also looked weirdly… fresh? Like, not something a store would sell. Any ideas what it could be?

Male ptarmigans will often stand on the lookout for predators. This behavior also means that predators are more likely to spot him, meaning he essentialy acts as a decoy, while his mate and chicks stay hidden nearby

Gopher vs Chipmunk

I watched a gopher and a chipmunk fighting today (Manitoba, Canada). The gopher killed the chipmunk. I went to check it out, the chipmunk was definitely dead, the gopher scurried off. Went back to my window to watch and the gopher returned, appearing to start eating(??) the chipmunk. When I went closer again, the gopher grabbed the dead chipmunk and dragged it into the bushes and out of sight.

From my quick research gophers are herbivores and this would have been very weird behaviour for one. Can anyone explain what else may have been happening?

give me YOUR niche animals to make as models for my game thing

[im not going to state the game name, what it’s about, or what platform it’s on as respect to the no self advertising rule]

anyways

im currently making a silly animal game with simply yet quirky designs for the critters, and I wanted to do something fun and ask the people of the zoology community for animals that they’ve desperately wanted representation of in the media but haven’t gotten it yet, or just animals you find very intriguing!

I will attach pictures of your suggestions to your comments, as these models typically take around 5-10 minutes to make depending on the complexity of the animal :)

I do have some rules tho:

  1. No elephants, giraffes, or common hippo submissions
  2. No aquatic species, ex. fish, porpoises, octopus, etc.
  3. Recently Extinct species from the past 3,000 years are allowed as suggestions
  4. No dinosaurs bruv

have fun!

Why do some Asian Elephants have lighter patches of skin?

pictured in the first photo, I am curious why some Asian Elephants have these areas of lighter skin, often speckled with darker bits, while others don’t have them at all. It seems different subspecies have this more commonly than others from the images I’ve seen, with Sri Lankan elephangs having it the most. Is it a genetic thing, or an indicator of age, etc etc? I think these patches are beautiful and remind me of my own birth marks, so I’ve always been curious about this

I have a dumb question about bison/musk oxen?

So I know that bison and musk oxen have that big muscle hump over their shoulders for supporting their huge heads and huge neck muscles. But how do they not tip forwards when walking or running?

edit: thank you for the answers, I genuinely appreciate it <3

Documented cases of forced copulation among lions and other big cats

I came across this statement from a post about lion cannibalism which caught my attention:

>Lion cannibalism is a curious subject, as I, along with others, was under the impression that it is not usual for lions to eat other carnivores, let alone one of their very own. Jason Kipling of Umkumbe Safari Lodge sets the record straight and really emphasises the true nature of these apex predators. What makes them the powerful rulers they are is their instinct to survive, and this, according to Jason is purely a display of that predisposition:

>“As far as I’m concerned this is not totally abnormal behaviour, although lions are not usually considered tertiary consumers they will not let a potential meal go to waste … The killing of an outsider is mostly just eradication of potential competition and the dead animal a source of protein and nutrition that will not go to waste." In the words of a professional, the images of those Delta lions feasting from the belly of their fallen relative don’t seem so upsetting and unnatural.

>Courteney Blunden, owner of Africa on Foot, responds to my query about this unusual kill scene with a reference to the Kruger National Park’s most notorious male coalition – the Mapogos:

>“This behaviour is fairly common and it can basically be brought down to pure survival instinct. Lions like the Mapogo males were famous for killing and eating many lions during their reign of terror. Remember the female in the Ross Pride who killed and ate countless cubs including the one white cub in 2012!”

>Jason’s experience in the Sabi Sand and keen interest for Big Cats also refers us experiences with the Mapogos. He says, “I have, on a number of occasions, witnessed lions feeding on another lion. If a lion is caught outside of its territory and killed it is often eaten by the attacking pride/lion. In the Sabi Sand, the well-known Mapogo coalition of 6 males killed and ate many lionesses, often even ‘raping’ them in the process as a show of dominance.

Emphasis is my own.

This made me wonder how many documented instances of forced copulation among lions and other big cats there are. Even domestic/house cats are known to engage in some...peculiar sexual behavior and other morbid acts like infanticide are well-known to experienced cat owners. Can anyone here add to the above?

Animals who rely on claws versus teeth?

Predators, as far as I’m aware, usually have both. I saw a reference on the Wikipedia page for hyenas that they use their teeth rather than their claws when confronting prey. I wasn’t able to find anything in my cursory searches that show there’s specific categorizations of predators who use teeth vs. ones that use claws.

Is there? I would appreciate examples of both, since I’m looking into this for a project. Thanks in advance !
