Norweigian ridgeback, Peruvian Vipertooth are the first two. But for second two I`ll guess Hungarian Horntail and a Ukrainian Ironbelly" said Barry hand raised.

Professor Morgan shifted uncomfortably on her little wooden seat, leaning forward slightly with the both palms flat on the stool. While she listened, she couldn't help glancing repeatedly towards Less and Annie. She shrugged when she caught Zan's look, blushing instantly and silently prayed that things wouldn't get out of hand.
Smiling at Clifford's enthusiasm, and utterly thankful for him bringing her attention back to the class, she rose from her seat and said, "You're absolutely correct, Clifford." As always, she thought. "The Peruvian Vipertooth, yes. Who has another?"
"Very good Herminny!" Iliana said, flashing her a smile.
"Celandine, I'm impressed with your logic. That's exactly right." WOW! This girl was on fire tonight "The five venomous dragon breeds are the Portuguese Long-Snout, the Antipodean Opaleye, the Hebridean Black, the Norwegian Ridgeback and the Peruvian Vipertooth."
"That's an excellent question, Tobias. One I honestly don't know the answer for." She said. Then she held up her hand to the side of her mouth and playfully whispered. "But I bet Professor Truebridge does." Winking at Tobi, she lowered her hand and smiled.

"Though I have to wonder, even when up against humans, is there really a need to subdue a dragon's prey? Unless perhaps said dragon plans to save its prey for later." She mused. "Once a dragon is close enough to sink its teeth into you, there won't be much opportunity to fight it off. And your theory does coincide with my next question. Thank you, nice work."
"Yes Barry, very good." Iliana nodded her head again and looked over the class. Happy that things seemed to be quieting down a bit, she breathed a sigh of relief.

"There are three types of venom exhibited by dragons. Does anyone know what these are?"

Cela raised her hand, confident in this one considering all the lectures on poisons she'd accidentally had to listen to, "Hemotoxic-and thats also spelled out with an 'a' between the H and the E- is a kind of venom that effects the circulatory system, like your organs and stuff. It's the one that hurts the most. Then there is Neurotoxic, that one is the most deadly kind of venom because it effects the brain and the nervous system. It makes people have fits and froth at the mouth and stuff. The other one is Cytotoxic, and that one is like a break down on a cellular level at the site of the bite. Thats the kind that itchy bites and stuff are. It isn't like, less serious cos you can still die from all of them and sometimes there are mixtures of the three kinds in venom, but in general thats how it goes." Celandine nodded firmly.

Herminny raised her hand and said, "I know some dragons exibit doxy venom, but I honestly don't know the other 2 though".

Upon hearing the Professor ask a question, Anna perked up, figuring she better stop thinking so intently about meeting a dragon and start thinking more about the actual lesson that was going on. She'd spaced out a bit and missed a good portion of the lesson, but she'd heard the professor this time---three types of venom exhibited by dragons. Anna shot her hand into the air, a bit prematurely, as she hadn't exactly figured out the types yet...but she would...hopefully. Seconds ticked on, and Anna still hadn't figured out what she would say now that her hand was raised. Finally, as if a lightbulb turned on in her head, the answers came to her, and Anna opened her mouth to speak. "Okay, so the first type would be Neurotoxic. This poison affects the nervous system and causes damage to the nervous tissues. It works to disrupt or kill neurons, which are cells that send signals to our brain. This would be the type of poison that would drive a person absolutely insane. What a sad, sad situation it is when a person is forced out of their mind due to being bitten by a creature," Anna said, shaking her head. "Then we have Haemotoxic. This poison affects the blood system and works to destroy red blood cells. It also affects the organs, making them...I guess...shut down. People have even been known to lose limbs from this type of poison! The third type would be Cytotoxic, which is damaging to the cells. Even though all three are destructive, I'd imagine Cytotoxic to be the most destructive. After all, cells are the building blocks of life, right?" Anna asked.

Chris Potter raised his hand excitedly. "Well professor, the three types of venoms are Neurotoxic, Haemotoxic, and Cytotoxic. These venoms each have there own form of damage they do to the body. Neurotoxic,which its name helps describe what it is, harms the nervous system. While Haemotoxic damges blood. And lastly Cytotoxic which direclty attaks your cells."

"That's exactly right!" Iliana beamed at her. "Celandine Toussaint, you are my superstar today." She said tossing another chocolatey treat her way. "Brava!"

"For those of you that answered Neurotoxic, Haemotoxic, and Cytotoxic, you are correct." She winked at Ethan, clearly proud of how well her their students were doing and then tapped the blackboard again.

Quote:

Types of Venom Neurotoxic - Nerve acting poison Cytotoxic - Cell acting poison Haemotoxic - Blood acting poison Cytotoxic Cytotoxic venom has a localized action at the site of the bite, it destroys and damages on a cellular level. Hemotoxic Hemotoxic venom effects the blood and organs, causing a breakdown or inflammation in the body. Hemotoxic bites are the most painful as breathing hurts and tissues start to die. Neurotoxic Neurotoxic venom, as the name suggests, effect the nervous system, leading to everything from seizures to death. Neurotoxic bites are the most deadly.

"It isn't as simple as sinking in the fangs and injecting venom into its prey; there are different kinds of fangs and different venom delivery systems. What is the process by which a creature injects venom into another creature called?"

Damn! I know this!

It hadn't been too long ago when he'd been going through some books and seen that awesomely mega cool word. Suddenly remembering, Jake thrust his hand up into the air. "Envenomation, Professor?" he said, stating the answer as a question, unsure whether it was right or not.

Cela caught the chocolate frog in glee and shot a look at Kayla, knowing the other girl couldn't do anything about candy she'd earned in class. Cela raised her hand, "Envenomation?" She ripped into the chocolate frog and began to nibble on it immediately.

Chris listened to the question it sounded like Envenomation. "Isn't Envenomation the process by which a creature injects venom into another creature , Professor?"

Eep! Today's Care of Magical Creature's lesson was hard! Anna found herself having to think a lot harder than she usually did. She was ready to meet the dragon already! Learning all about his venom was proving to be quite difficult! Nevertheless, Anna decided to attempt an answer anyway. Raising her hand, she said, "It's called envenomation, Professor," she said. "Snakes and spiders envenomate, as well."

Herminny raised her hand and said, "I think it's envenomate ma'm".

Tobi raised his hand, and started splitting hairs, it wasn't necessarily a good idea, but he wanted to point something out, "It's envenomation Ma'am. Though interestingly, it's one of those things like, every gecko is a lizard but not every lizard is a gecko?" he wasn't sure if his analogy had quite come off. "Because envenomation refers to the delivery of venom into another creatures body, but not necessarily through biting, though that's the most common. It can also be done by external application to sensitive tissue like the area around the eyes, or in the eyes themself, or ingestion. As far as I know, there isn't really a specific term for envenomation by biting. Is there?"

Feeling energized by the amount of student participation, Iliana began tossing her little frogs to each person with a correct answer. When she heard Professor Bunbury's answer she laughed out loud, shaking her head and walked over to personally hand her TWO frogs. Taking the opportunity to get a good look at her up close, Iliana tried her hardest to read the pretty professor's expression. When she was positive that her behavior just had to be part of some elaborate practical joke, Iliana smiled and walked back over next to Ethan.

"Very good class, envenomation is correct. Though envenomation does not occur with every bite, and death does not occur with all venom types. Any ideas as to why this might be?"

Chris raised his hand with a theory. "Perhaps it doesn't happen with every case becuase, the fangs or teeth may not pierce a vein or artery or the vitim may get the venom out before it spreads."

Cela took another chocolate frog quite happily and thought about the question.

She raised her hand. "Well, they can sometimes control their venom right? And they might not want or need to waste it, like when they bite, depending on what they are biting? And as for not always dying, its 'cos some venom isn't deadly and also because some prey might be resistant."

She raised her hand. "Well because some venoms aren't designed to kill . Some neurotoxins are just to stun their prey or their hunters to they can get away or eat them later after they have dragged them to their lair." She offered.

Kayla raised her hand, "Well perhaps like Celandine said they may not want to kill straight away. They could use their venom to paralyse their victim and render them into a weakened state, so that if they don't want to eat straight away they can leave the leave the blood warm and flowing until later when they are hungry." Cause who wants to eat cold meat?

Raiden raised his hand tentatively. "Well... don't they have to choose to envenomate something? So if they don't think it's worth the effort, they don't bother, do they?" He scratched his head and thought for a moment. "Some of the venoms are probably just to paralyze their prey. So they can't get away, but they won't die either. In case the dragon maybe saw something tasty, but decided it didn't want to eat it until later?"

Though envenomation does not occur with every bite, and death does not occur with all venom types. Any ideas as to why this might be?"

Cedric raised his hand.."envenomation does not occur with every bite,..maybe there's some other parts of the dragons that have a venom not only their teeth..like the sting ray..its tail has a venom so there's a possibility that
dragons have a venom not only in their teeth.....",Cedric explained

"and death does not occur in all venom types...maybe the venom of the dragons are not so effective to the people it bites....some other people drinks the dragon bloods especially the one one who has a tribe but they are not died even though dragons have a venom in their body.."Cedric answered

Anna happily accepted her chocolate frog, hugging it close to her with happiness. My how she loved chocolate frogs! Anna eyed the two frogs Professor Bunbury had received. Yummm. Hearing the professor ask another question, Anna raised her hand. "Well, some creatures can actually choose not to inject venom with their bites. In this case, they'd only bite to defend themselves in some sort of an attack. A 'dry bite' happens when a creatures bites but does not inject venom," she said. "This would be one reason why death would not occur. Another reason would be that the fangs might not have penetrated the skin, therefore the venom wouldn't get into the body."

Tobi had his own stash of chocolate, so he figured the gentlemanly thing to go would be to pass his to Anna. Cela had had enough chocolate. He'd give her a chili cream after class. Meanwhile he raised his hand and threw in his guess,"Ma'am while there are three TYPES of venom there are countless venoms out there, and many are more potent than others." he said, "Even if we forget that for a second, you need to consider location of a bite or envenomation. It's like anything else: imagine getting stabbed in the muscle tissue of your shoulder; it would hurt, but it's probably not fatal. Now imagine getting stabbed in the carotid artery - you would have as little as 15 seconds left on your life if you didn't get immediate help. So consider now being bitten in your big toe by something carrying a mildly cytotoxic venom. That venom probably wouldn't make it all the way to your heart if you acted quickly, besides, you may have the white cells and antibodies to fight off the venom. But being bitten close to an artery would carry the through more of your blood stream, where it can do more damage quicker. Now imagine if it were a more potent venom too."

Wheew! Didn't HE feel like he suddenly swallowed a textbook. He blamed Nona.

"Ah." Ethan tapped his nose, "Not quite."

"Thats right. Again." Ethan nodded at the Ravenclaw, unsurprised she was at the top of her house.

"That is one of the contributing factors, very good." Truebridge nodded.

"Right." Kayla Winters was on fire.

"Right." Ethan nodded and folded his arms across his chest.

"I like that you are thinking, Cedric. However that isn't quite what we were looking for. And all dragon venom is effective for the purpose it is intended for."

"Right. They can choose not to inject the venom." He nodded.


"Good example, Tobi." Truebridge nodded. "Now, a few of you mentioned that a dragon, or indeed most any venomous creature, can often choose whether or not to envenomate. The reason for this is because venom stores are not unlimited and it usually takes a minimum of four days for the venom to be replenished. A reason death does not always occur because not all venoms are intended to kill, some are to incapacitate. Like Anna said, there is such thing as a 'dry bite'. But don't get to excited, if you get bitten by a venomous dragon and it is a 'dry bite', there is still the matter of having just been bitten by a dragon."

Ethan tapped the blackboard and more notes appeared.

"In general, there are four categories as far as Dragon fangs are concerned. In the most simple sense, they are; fangless, fixed fanged, folded-fang and rear fanged. Generally a creature which is fangless, is not venomous. Those that are tend to carry their venom in their saliva rather than in specialised venom sacs. There is one dragon that defies this generalisation, as I will explain in just a moment. Dragons are similar to snakes as far as venom delivery systems go. That goes for both magical and mundane snakes."

Ethan looked around the class, noting that apparently there were quite a few candy fiends.

"When harvesting dragon venom, it is important to know about the type of venom, fang and venom delivery system the dragon has. Can anyone guess why?"
