Arthropods can get humongous. The main reason they don't is they are far too tempting targets for warm-blooded vertebrates.
But about that? Why couldn't an arthropod also be warm-blooded? Maybe some were.
And that thing you heard about "giant insects needed higher O2 levels" also questionable. Arthroplura was still around after the levels crashed... something else ended the golden age.
@futurebird It depends on what you mean by warm blooded. There are a whole bunch of moths that can generate their own body heat for flight (endothermy), although they don't maintain a constant body temperature (poikilothermy).
Where to get all-day #currypuff (karipap) in #PetalingJaya ? Seems not as widely available these days, other than some early morning nasi lemak vendors. And I don't mean the fancy $5+ ones from restaurants either. #malaysia
@art_history_animalia That's not a bee. The front legs, thin hind legs, short wings and face look like a cicada nymph. (It's a good carving of a cicada though, all the details are accurate)
@irfan Munchkin cats, dwarf cats, there are a few breeds of cats that are cute but do all sorts horrible things to the insides of the cats. They exist but most reponsible breeders dont do it for ethical reasons.
