Quote:My attention was so laser focused on the task at hand that it took me awhile to notice the odd tickling sensation on my right arm.

Someone cleared their throat in front of me. I ignored them, and waved my wand over the cauldron.

Awesome, it’s the right shade of red. Now I just need to turn the burner up and wait about fifty minutes…

Someone cleared their throat again.

I turned the burner on, set my timer, and THEN looked up.

Snape was standing over me holding a clipboard and looking pointedly at my right arm.

I looked over at my arm.

Oh. I’m on fire. Well, that’s annoying.

“Extinctus.” I muttered and waved my wand over my arm. The fire went out instantly. Next to me, Mandy’s workstation seemed to be on fire too. I waved my wand and cast the fire extinguishing spell on Mandy’s area too. I really didn’t want the smoke to affect my potion.

I looked back down at my ingredients. I needed to crush the mistletoe berries so I was ready to add them to the mixture…

Snape cleared his throat again.

I looked up.

Was he trying to sabotage me?

“Miss Thompson, are you hurt?” Snape asked sounding more annoyed then concerned.

“No, sir.” I waved my hand in the air dismissively. “It’s just a little fire.”

Snape raised an eyebrow.

“I cast the flame freezing charm on myself this morning before breakfast,” I elaborated so he would leave me alone to brew.

Snape made a face like he was passing a kidney stone, made a mark on his clipboard, and then moved on.

I focused back on my ingredient preparation.

An Introduction To Dragon Biology, 17th Edition, Oxford University Press, 1793 Wrote:Given the variation across the breadth of dragon biology, it is ultimately self-defeating to speak in anything more than the broadest of generalities on the topic of draconic senses, as there are specific types and breeds and even individuals with exceptional versions of each of the main senses.  However, broad trends can still be observed. 
Dragons tend to have high visual acuity, especially for low-light environments: the majority of dragons are trichromats, but one genetic line possesses a mutation that grants them tetrachromacy, and another line being bichromatic but with exceptional low-light vision (highly prevalent among Boulder-class dragons).
Hearing nearly universally manifests in a wider range than that of humans: the common range reaches down to 15 cycles per second and up to 22,000 cycles per second, with some lines having greater or lesser limits, the lowest limit ever documented being 3 cps.  The majority but not totality of draconic communication conveniently happens in the same vocal range as available to humans, but dragons use the lower-frequency ranges for long-distance communications.  While only simple information can be communicated using this method, historically it was used for navigation to and from nests and over long distances.
Smell is significantly more acute in comparison with humans, with some lines having acuity on par with canine bloodhounds, but all dragons are highly sensitive to scents…
