I was trying to backtrack a "common knowledge" claim that pandas give birth to twins about 50% of the time. Unfortunately, the Wikipedia article (and most Google results) led back to a news article citing an unnamed zoo official.

What other scientific research exists to support this claim? Have other studies been done? I would love to see the research/methodology behind this fact.

Thanks!

So humans, we have muscle atrophy if we don't exercise or sit still for too long. we have to work out consistently and eat a specific diet to reach peak muscle capacity.

I get that lots of animals 'work out' through their naturally active life cycles like hunting and playing and running. But i guess i have a hard time understanding why animals like gorillas and chimps are *so* much more muscular than humans and are that way naturally without having to consistently lift large things to grow muscles.

Also, ambush predators. frogs, crocodiles, lizards. They sometimes sit still for months at a time, but their muscles don't suffer from disuse atrophy. Crocodiles are incredibly strong but they don't exercise whatsoever. Is there something special about their muscle structure compared to that of humans? Are humans designed to be lean and low muscle mass and maintaining large muscles via exercise is unnatural for us and that is why it is so hard to obtain and maintain high muscle mass?

I read online that deer love strawberries. I've been taking care of a family of deer that live on my property, I feed them deer corn but today I was out of corn and they came by wanting some food so I tried to give them strawberries but they wouldn't eat them. there's about 10 or 11 of them now, usually new babies show up once or twice a year.

I also tried giving them grapes but again they licked the grape and then walked away from it.

How come these deer don't like fruit? They're white tail deer from the central east coast of north america.

Hello, denizens of r/zoology!

It's time for another weekly thread where our members can ask and answer questions related to pursuing an education or career in zoology.

Ready, set, ask away!

Im a highschool student and my zoology textbook (a bit old) says that flatworms are considered diploblastic organisms because their parenchymal layer(between ecto and endoderm) is not fully developed into a mesodermal layer. However, most resources on the internet and another zoology book written by a different author says flatworms are the first triploblasts and that their mesoderm, divides to form parenchymal layer and not the other way around.

Confused between veterinian and zoologist 😄

When i Go to Wikipedia i learn a some sort of weird Pattern for example when it's a Very famous species or it's often called charismatic megafauna the page is long and they show a picture of a Very famous Animals(ex Lion great white shark bald Eagle) They not only show the Full picture but the page is Also long,however If the page shows only the drawing of a animal or Not even show the picture or drawing of the animal at all the page is too short and sometimes It even becomes a sub,can someone explain this?

Why was the Galápagos tortoise once thought to be it's own species then became a species complex and then became its own species again?

Is animal behavior the best or worst Way in order to know If a animal is a Single or various species?

Why do we need to find New species

Can someone explain in details that why in this year that the Green anaconda and the king cobra's taxonomy were recently questioned and they were possibly reclassifed into two species for the former and four species for the latter because i don't understand that story?

What is the reason that despite their least concern status Why was the pygmy right whale only seen or Heard from only drawings and Beached individuals until It was filmed alive between 2022 and 2023?

Why is sometimes the giraffe is treated like a genus with multiple species or sometimes as a monotypic genus with only one species?

What's going with the king cobra? I Saw it's page on Wikipedia and It says that the king cobra has become a species complex instead of a Full Blown or only species,can someone explain why is the king cobra's taxonomy is changing?

So obviously there is a common misconception that bats are blind, which I know has been debunked and revealed as just being not true, but I am curious to find any research or pockets of information directly relating to this matter to greater expand my knowledge of this fact, I am of course doing my own research as well but I am curious if anyone know's of any interesting research that has been done or somewhere I might see more information on this subject if I wanted to elaborate on it with other people.

A quick Google search told me that ! These tiny rodents can apparently bite with 7,000 PSI?

I find this highlighter likely to be true, since the strongest bite force on any animal live today belongs to that of the nilev crocodile which can deliver 5000 PSI, so this would imply that a tiny squirrel has near T-Rex level jaw power

And if this is actually true, how do the squirrels not break their own Jaws, force their teeth into their jaws whenever they close their mouths or chew acorns

I want to pursue zoology but i want to be able to travel and ive recently learned theres different jobs you can do and im not quite sure which one im meant to be looking at to travel and research animals if anyone could answer this at all with any answer its apreciated
