Interesting bit in the wikipedia article on hydrothermal vents.

Seems that the giant tube worms found there use hemoglobin...

They use it to transport hydrogen sulfide to the bacteria that live
in their bodies. The bacteria use the H2S to produce ebnergy and the
compounds they excrete are what the tube worms live on.

Now *that* is a use for hemoglobin  I'd never have expected!
