Actually, yeah, I do! I’ll post that in a few minutes - did you know that our average mortality rate from blood harvest is down to a historic low? Less than 2% of the animals don’t survive the process, and we’re still learning tons from the hemocyanin in their blood, not least of which includes potential new treatments for several hemophilias!
