How does blood pH vary across species? I can't find an article or chart listing this kind of information.

So far I've found bits and pieces like:

But no real comparison.

Is there an authoritative comparison of blood pH between: mammals, reptiles, fish, invertebrates, etc.?

Is nominal/average pH at least constant across all mammals, or across all reptiles, etc.?

  • $\begingroup$ Don't forget most plant life needs soil that has a pH of 6.0 to 7.4 to dissolve nutrients easily, so you might as well add plant life to your list $\endgroup$ – user5434678 Mar 16 '16 at 6:43
  • $\begingroup$ @TheVoid, Sure, any plants that have blood. (^_^) $\endgroup$ – Brock Adams Mar 16 '16 at 7:24
  • $\begingroup$ Its all life that needs a pH of level of 7.4 to be in the Alkaline. That is wear life can thrive at its fullest potential. $\endgroup$ – user5434678 Mar 16 '16 at 7:38
  • $\begingroup$ in reptiles variation from 6.5 to 8.1 have been observed. ectotherms in general have a broader range. jeb.biologists.org/content/jexbio/203/13/2065.full.pdf $\endgroup$ – John Mar 18 '17 at 1:57

    $\begingroup$ oh sorry that was the reference for the ectoderm statement. here s the reference for the PH values. seaturtle.org/pdf/… $\endgroup$ – John Mar 18 '17 at 2:28
