Mosquito teeth

Post by Gord » Sat Jan 13, 2018 11:04 pm

According to Isaac Asimov's Book of Facts, the average mosquito has 47 teeth. But that's not technically correct (the best kind of correct!). A mosquito's proboscis is formed from its mandibles and maxillae into a needle-like structure called a stylet which it uses to pierce the skin.

Image goes here: http://bugs.bio.usyd.edu.au/learning/re ... quito.html

There are structures on the maxillae which some people call teeth, even though they are not actually teeth* (another image goes here). The number varies by species, but the number 47 seems too high -- I'd expect something more like 24 or 30. It's also an odd number, and since mosquitoes are symmetrical, the usual number for any one mosquito would tend to be even, so it's like saying the average roll of a 6-sided die is 3.5.




* except in the sense that saws, keys, and combs have teeth, too; but in biology I think this is the type of thing you'd expect when you hear the word "tooth": https://en.wikipedia.org/wiki/Tooth

Whats the issue? That there are an odd number of teeth? I go with your symetry argument, but.........it might be an exception to the rule. You know about exceptions? Could still be an odd number of elements to the stylet with some other ancestral part being bent to the purpose? Insect are fascinating creatures. All those parts doing all those things in such small packages. In some other evolutionary chain, I have wondered just how intelligent a creature could become at a very small size. Do you need thumbs?

The issue is that mosquitoes don't actually have teeth.

I opened a back of Dubble Bubble gum today and was confronted with that bit of misinformation.

I assume teeth was just an analogy? That some odd number of parts came together? No??? Just a bad bubble gum wrapper?................................. I hate it when that happens.

Shark teeth are more interesting. They are modified scales, called denticles. They are mounted on skin that moves forward, like a conveyer belt, constantly putting new teeth into place for biting, as the old teeth break off. They are razer sharp. Dozens of them. With constant replacement, no need for a toothbrush or a dentist.

Shark teeth come in all kinds of shapes and sizes. The grey nurse has dagger like teeth, facing back, that grip fish. The white pointer has teeth like short knives to slice off flesh. The carpet shark has teeth like sandpaper backed by hard tissue, to crush shellfish.

And when they smile, the teeth are awesome!

Gales have teeth, so I don't see why insects can't have 'em.

Pianos have teeth, and they aren't even symmetrical......the best ones aren't anyway.

Gail has lots of stuff mosquitoes don't have.

Pianos have keys, which could be made out of teeth.

Buicks have keys too, but that doesn't mean pianos are Buicks. Well, except for this one: https://blog.carsforsale.com/wp-content ... elabra.jpg

Declines can have teeth.

No. Wait. I'm thinking of the Clines.
