Thread: Imagine Dragons....

I was talking to my sister, who was trying to write a book, and she mentioned venom in dragons. I questioned why a species would feel the need to develop venom after exerting so much energy into size, and this led to a talk about the economics of such a large carnivore existing at all.

What kind of ecosystem would need to be in place to supply these creatures with the food they need? They either eat a lot, or are very lazy (which means no wings, because that's a black hole for resources)

I realized I'd never seen a story with dragon's that properly reflected the ecological consequences of such a thing.

This is not a biology question this is a science fiction question

The question is about the ecosystem required to support large carnivores. The example was fictional, but it's still a biology question

Then to come close to making a reasonable guess you would have to decide on the mythical attributes of the mythical creatures.
Are they warm or cold blooded?
How big are they?
What is their metabolic rate?
What is their sleep same cycle? Etc. Etc.

Given that we have decent examples of those permutations in the fossil record, I see no reason this topic can't be explored. Theoretical biology is a perfectly reasonable topic

Just off the top of my head they would need an ecosystem with plentiful prey animals with no real competition. Or maybe competition would be good to develop the venom and other dragon traits? In any case food being easy and plentiful to find would encourage the larger size.
