Speculative biology is simultaneously a science and form of art in which one speculates on the possibilities of life and evolution. What could the world look like if dinosaurs had never gone extinct? What could alien lifeforms look like? What kinds of plants and animals might exist in the far future? These questions and more are tackled by speculative biologists, and the Speculative Evolution welcomes all relevant ideas, inquiries, and world-building projects alike. With a member base comprising users from across the world, our community is the largest and longest-running place of gathering for speculative biologists on the web.

While unregistered users are able to browse the forum on a basic level, registering an account provides additional forum access not visible to guests as well as the ability to join in discussions and contribute yourself! Registration is free and instantaneous.

David Darling's website has a page about blood varieties. Regarding blue/hemocyanin blood:

Could advanced forms of blue-blooded life - the equivalent of mammals, say - exist on other worlds? Conceivably they might on planets with high surface pressures and abundant oxygen, where great oxygen-carrying efficiency wouldn't be at such a premium.

Wouldn't a higher-oxygen atmosphere enable hemocyanin to function better?

Also the novel Fragment by Warren Fahy (mentioned in this thread) had highly-active creatures with blue blood:

"Here's what we think: the copper-based blood pigment in these animals is superefficient," Quentin told him. "It exhibits a Bohr and Root effect more dramatic than that of any organism I've studied."


Andy stepped in. "Bohr and Root effects are what keep marathon runners like Zero here going."

"Under stress," Quentin explained, "blood chemistry changes to deliver more oxygen to muscles so you can run faster, longer."

"And?" the bewildered presidential envoy demanded.

"The copper blood in these things delivers more oxygen in a single heartbeat than any pigment I've ever tested, from bumblebees to cheetahs," Quentin said.

I'm not a biologist though, so I don't know how accurate that is :D
