...that tarantulas have no hemoglobin in their blood. This brings up the question 'how does oxygen get around their body'?
Also they have no platlets in their blood so if you drop it, it will most likely die. So when they say don't handle tarantulas it's for their health as well as your own.
They have really screwed up blood don't you think?
PS if you have read any of my other posts today I'll admit I'm obsessed with them just now.

Tarantulas use hemocyanin as opposed to haemoglobin, hemocynanin is copper based as opposed to iron and its a protein bound to a metal ion cofactor ( combined these are called metalloproteins). This binds a single 0

molecule, but unlike haemoglobin that binds it as a ring, these are more 'stuck on the side' as a prosthetic group.
Other than a little biochemistry I don't know a massive amount about them, but I think hemocyanins are common in crabs and molluscs type creatures.
