What about spitting acid? I don't mean weak acids like stomach acid or citrus, I mean major acids that could melt muscle and bone quickly. It would be a weapon, and it would get pretty complex, but acid spit is doable. All you really need is a system to keep it from corroding the inside of your creature. I think that a large amount of saliva in the storage area for acid would work, sort of like a saftey net. (BTW, I searched for things along those lines, there weren't any. Sorry if you already have something like this or a suggestion like this.)

Strongly thermal organs? Going beyond heat transfers in the blood that actually produce heat using various reactions? Arctic dweller has movable heat pad for thawing food and melting ice without cooling it's own body. No clue if a strong heat removing is possible in biology (I honestly doubt it based on earth) but I'm aware of a few animals that produce heat beyond warm-bloodedness

Waxy Monkey Frogs have a gland that produces a substance which is kind of like sunscreen. It pretty much allows them to sit in the sun longer without drying out since it's an amphibian.

Also, Bombadier Beetles have two pouches in their abdomens filled with two chemicals that when the mix them together it produces a volatile chemical reaction and the stuff explodes out their backsides and literally melts the flesh of the predators attacking it. It's VERY, VERY painful.

Also some sort of gland like poison dart frogs which get their poison from venomous ants in their ecosystems. So, if your creature doesn't eat enough of a certain prey item, it isn't poisonous anymore.

So I guess those would all be glands, do you guys like the ideas?

I remember "odd lumps" being mentioned in the concept. Would it be possible to store water in the humps, like a camel? I didn't see anything about it, just thought I should ask. (I remember that there was a suggestion for special sacks that would hold water, this would be similar to that.)

whoops, sorry. But would something like the water storing hump be possible? I also read about the fat application in the concept. I know, this is a stupid question, but when you apply the fat to a hump, would it make the hump itself grow bigger after eating? (not just were the fat was applied, but the entire part)

Okay. Now, I have two things to cover: Eyes and the dragon-fire breathing thing.

First off: Eyes. Have compound eyes (insect eyes) been thought of yet? Also, I remember UV-detecting and Infrared-detecting aspects being discussed in a camouflage thread, but wasn't really discussed. Are those types of eyes suggested?

Also, there was the whole dragon-fire-ability discussion. Would it be possible to swallow platinum, have it get sent to a special sac were it is stored near another sac holding the hydrogen, and then be able to have the two mix together bombardier beetle style?

It's okay, the main thing I was wondering about was the eyes.

One last thing: You know flying squirrels? Would the flaps they use to "fly" (glide) be handled in the skin tab or the wings? (I remember that wings were talked about in the concept.)
