Various sites claim our body creates (and destroys) about 2 million erythrocytes/sec. Yesterday, I had a kid compute the correction increment required for his growth. I think we overshot by a factor of 2 by using a (presumably adult) count of 2*10^13, getting about 63000/sec. This roughly coincides with the total of vertebrate species, all but 25 of which have erythrocytes! Do see http://en.wikipedia.org/wiki/Channichthyidae. It's enough to warm the subzero heart of a Creationist. --rwg
Also, no coronary arteries, likes subzero seawater, faster than a speeding brinicle. (https://www.youtube.com/watch?v=r4cX2EPt2zE) http://newsinfo.inquirer.net/582509/how-deep-can-fish-go-scientists-may-have... suggests fundamental biochemistry limits fish to shallower than 8.3km. In light of Channichthyidae <http://en.wikipedia.org/wiki/Channichthyidae>, I would be amazed. --rwg
