And as for the type of venom... well, I think only certain types can be used for potions and other things right? Some kinds... will mess it all up." There had to be a better reason than that. "Uhm... and if it's acidic venom, that melts stuff, you'd want to know that... so you would have the right thing to collect it in."
OOC: if we're still doing sources... I'm running off my brain, thank you. >.> Doesn't seem to work in Raiden's favour. | Quote:

So you can do it quickly and not have to use spells or potions that make subdue the dragon for longer than neccessary."
ooc: um if I don't stick a thingy bout my source its cos its a brain thing. | Quote:

No point going in there with container to collect the venom, if it's going to be so potent that it like melts your container or whatever. It's also helpful to know what type of fang the dragon's have so that when collecting the venom you know where to look and also what to avoid, it is also essential to know the venom delivery system so that you can avoid being bitten by the dragon."
ooc: that would be me taking a good hard guess | "Exactly, good answers all of you. Aaaand here are the details about the venomous breeds and their venom delivery systems. It would be useful to take notes."
Ethan tapped the board again as he spoke, "There are a whole bunch of hard to pronounce words coming up, but do be sure to take note. We will be moving on very soon." Quote: Antipodean Opaleye (mild, non fatal Cytotoxic venom) Aglyphous (grooveless) venom delivery system
The Antipodean Opaleye lacks any groove in their teeth for venom to run down. Instead the venom drips down the teeth from any available opening essentially saturating the maxillae. In order for envenomation to occur the dragon must chew on it's prey which is time consuming, but as the venom is meant to incapacitate rather than kill, this is as efficient as it needs to be. Norwegian Ridgeback (Highly Venomous Neurotoxic venom) Proteroglyph (front groove) venom delivery system
Proteroglyphs (front groove) dragons have a groove that has run so deep that both sides of the groove overlap eachother forming a channel for the venom to flow. A lumen is located at the base of the tooth where venom awaits ejection, while a discharge orifice lay on one side near the tip. An adductor (jaw closing) muscle is attached to the glands so that when the dragon bites down the glands get squeezed and a stream of venom flows into the prey.
Proteroglyphs are fixed fanged, That is to say they are unable to fold up their fangs when not in use so the fangs must be kept short enough so as not to puncture the lower jaw. Hebridean Black (Moderate Hemotoxic Venom) Opisthoglyphous (rear grooved) venom delivery system
Opisthoglyphous (rear grooved) dragons have elongate fangs located on the top of the back of their mouths. These fangs have a groove running on the lateral side of the fang which helps direct venom into the prey. Since the fangs are located posteriorly the dragon must make a point of taking a big bite into it's prey in order to assure envenomation.
Portuguese Long-Snout (Moderate Hemotoxic Venom) Primary Proteroglyph (front groove) and secondary Opisthoglyphous (rear grooved) venom delivery system.
The Portuguese Long-Snout has a dual venom delivery system, the fangs are connected to the same venom glands. Peruvian Vipertooth (Highly Venomous; Primary Neurotoxic venom, secondary hemotoxic venom) Primary Solenoglyphous (pipe grooved) fangs and secondary Proteroglyph (front groove) fangs.
Solenoglyphous (pipe grooved) fangs have the groove so deep now that the outside of the teeth completely cover it forming a pipe for venom to enter. The two fangs are attached to a short highly movable maxillary bone. This bone allows the dragon to fold its fangs up in its mouths. This ability to fold up the fangs allows for greater fang length. the fangs hyperextend (up to 180 degrees) but with the separately jointed maxillae the fangs can move individually as well. So a vipertooth can decide whether or not to move one fang or two. Inject one side or two. The amount of venom control in a vipertooth is astounding as is their venom reservoirs.
The secondary Proteroglyph (front groove) fangs are short so they do not puncture the lower jaw. The Peruvian Vipertooth is unique in having a seperate reserve of venom for each set of fangs. These secondary fangs give the Vipertooth the ability to spit their venom, generally as a defensive measure.
The secondary fang tips have beveled, spiral apertures on the anterior surface just above the tip where the venom is ejected. The spiral groove forces a spin on the venom allowing for greater accuracy when spitting.
| Ethan opened the wand case he'd been carrying and carefully drew out his old wand, still split almost directly down the centre by the secondary fang of a juvenile Peruvian Vipertooth. the Fang was the length of his hand and a couple inches thick, his wand splintered around it.
"The dragon that we are dealing with today did this to my wand. This is one of the secondary fangs of a Peruvian Vipertooth." He held the wand so the class could see, carefully replacing it in the wandcase after just a moment. "You can never fully predict the behaviour of a dragon, but one thing for sure about the Vipertooth is that it is fast." Ethan paused.
"It will not be awake and therefore it's speed will not be a consideration, and I will be ensuring it does not wake up for the duration of the lesson. I am going to see to the dragon now, and Professor Morgan will bring those of you who have behaved along shortly." Ethan looked at Iliana and nodded at her, tucking his wandcase under his arm.
"I'll see you in a few moments." With that, Ethan headed off in the direction of the forbidden forest, to double check all preparations. |
