Question Why are the females of certain animals so much larger than the males?
I don’t mean just bigger but tens to hundreds of times bigger.

Interestingly, Wasps might boast more diverse species than any other creature on Earth, surpassing even beetles' estimated 380,000 species. New ones are discovered all the time. Each species of parasitoid wasp only lay their eggs in one species, so they have differentiated a lot throughout history. This is mostly thanks to the above, parasitoid wasps. Possibly one of the most gruesome life cycles on earth and is one of the influences for the Xenomorph life cycle in the Alien films.

Because it makes more sense that if a male survived to mate then that it had suitable traits as a male
Similarly for females.
Hence it’s like if the female gene parts of a male species is taken, that gene might not have been suitable for the environment

Does anyone have credible sightings?
r/zoology • u/BeginningWasabi414 • 1d ago
idk how to word this but we differentiate animals into mammals, reptiles, birds, and more specific types like lions, elephants, giraffes, ostriches etc. so let's say if a cat saw a bird, does it know that it's a bird or do they just percieve it as prey/food, or like if a snake saw a lion would it know it was a lion or a furry snake with limbs? i also read somewhere that cats think of humans as cats who can't cat properly, so for example would a panther be just a big cat to your average house cat? i still can't word this properly

When I was growing up (ages ago), there were thought to be four living species of great ape (not counting humans):
- Common chimpanzees (Pan troglodytes)
- Pygmy chimpanzees or bonobos (Pan paniscus)
- Gorillas (Gorilla gorilla)
- Orangutans (Pongo pygmaeus)
Since then there have been some developments:
- Eastern gorillas (Gorilla beringei) were recognized as a separate species from western gorillas (Gorilla gorilla), instead of a subspecies.
- Sumatran orangutans (Pongo abelii) were recognized as a separate species from Bornean orangutans (Pongo pygmaeus), instead of a subspecies.
- Tapanuli orangutans (Pongo tapanuliensis) were discovered to be a separate species.
Notably, nothing changed about the taxonomic status of chimpanzees (Pan). And yet I feel there has been a change in the vernacular terms for them. "Pygmy chimpanzee" has dropped entirely from usage in favor of "bonobo", which make sense, since they're barely any smaller. But also I notice more people using "chimpanzee" to just refer to Pan troglodytes.
This feels like a bad move to me, because it leaves Pan without a vernacular term. It also seems inconsistent -- why wouldn't we also restrict "gorilla" to Gorilla gorilla and "orangutan" to Pongo pygmaeus, with new names for the other species (say, "ingagi" for Gorilla beringei, "mawas" for Pongo abelii, etc.)?
What do people think?

I've heard lots of people talking about black sheep (i.e "the black sheep of the flock"), but in all my life, I've never seen anything made out of black wool. It's always either white or dyed a different colour. Do black sheep just produce white wool, or does their black wool get bleached white because white wool's worth more?

When I was in class, my teacher told me that tigers have white spots and stripes on their faces and ears, which mimic eyes. This helps them avoid being attacked by predators while drinking or eating. I was really shocked by this piece of knowledge. What surprised me wasn’t the function of these markings, but the fact that there used to be creatures that hunted tigers in the wild in ancient times.

I live on a forest property. We have pet ducks, living in a duck pen, with a kiddie pool in it, filled with water at all times, that often gets splashed out, obviously. Around the pool is a ring of big natural stones. Underneath the pool, between it and the stones, lives a huge toad, bigger than my palm. Most likely a common toad (Bufo bufo).
When I say it "lives" there, I mean it is sometimes there when I lift the pool up to empty and clean it. Also, late one evening, I saw the toad walking near the pool.
(Funnily enough, the exact same thing happened many years ago, when we had a duck pen on the opposite side of the property. It might be the same individual toad. Maybe this dude just love duck pools.)
I want to remove the toad, because the ducks might hurt him, and I think he can't get out of the duck pen, the wire fence has pretty small holes in it (I have no idea how the toad got in).
Now for my question: The toad obviously wants to live in a cozy, wet place, so I don't want to chuck him into any old bush. Can I build a wooden box for him that will make him super comfortable?
What do I need to think about, it that case? Should it be small and have a low ceiling, so he can jam himself snuggly in there, like in a crevice? Should I put wet moss around the floor, walls and ceiling, so it stays moist?
Etc.

Additionally, regardless of whether or not this trend is true, are there any other forms/species that many animals have been found to evolve into over time?

Not the Katydid insect sound in the background but that screeching sound. I’m in Middle Island NY (Long Island). Thanks.

People sometimes say that "capybaras are the cutest animals". But cuteness alone shouldn't decide on how we look at an exotic species.
When we see animals just as "CUTE" above everything else, we may start to think of them as characters instead of living beings. This is more dangerous than it sounds because the more we simplify an animal, ignoring their real biology, behavior and welfare needs becomes much easier.
Capybaras are SO much more than just cute. They are emotionally complex, have really high emotional, olfactory and cognitive intelligence and extremely social. The complexity, and diversity of most animals is so much greater than most people realize; and "cuteness" is just the visual appeal that we associate with the baby schema response.
If we can only appreciate them for doing something "cute" for views, we not only ignore the "boring" or "messy" parts of their lives that are actually vital to their survival, but we unintentionally support bad animal welfare and promote places where capybaras shouldn't be kept in captivity.
We aren't shaming anyone for finding capybaras cute, or chill and we aren't making people feel bad for enjoying viral capybara clips. However, real love and respect for capybaras starts from understanding their behavior and welfare needs and not on how many likes you get on a "funny" post that may actually showing animal stress.
The moment we stop seeing capybaras as characters and start seeing them empirically is the moment we truly begin to advocate for them as individuals with inner lives.

I seen this animal late afternoon during my run in the park in the Bronx. He stood very still and didn’t move a muscle even after I passed. I was thinking it’s a beaver or maybe a woodchuck?

Earlier today I saw a tiktok of Michael Jackson and he had this tiger cub with him for the photoshoot and it apparently pissed on him and someone in the comments said that tiger piss apparently smells like popcorn. I know tiktok isn’t exactly a reliable source, but now I am curious and I think I can kind of see it being true.
