From the comments, here’s something bizarre: creationists (at least the ones at Answers in Genesis) have defined life…and it excludes squid! I have yet another reason to reject the Bible, in this case for disrespecting perfectly wonderful invertebrates.
Many scientists make the distinction that vertebrates have hemoglobin,
hence red blood, and invertebrates contain other oxygen transporting
proteins, like hemocyanins, and do not have red blood. As far as
we’ve researched at this time, all vertebrates have hemoglobin and
invertebrates do not, though there may be exceptions we are not aware
So, animals that contain hemoglobin (vertebrates) and therefore have
red blood can be considered “living” and animals that contain
hemocyanin, or other proteins (invertebrates) and therefore have blue
(pink/violet or brown) blood can be considered “nonliving”. This is
further supported by Scripture since the Hebrew for “blood” (dawm)
is derived from the Hebrew for “red” (aw-dam). And with Genesis
1:20-22 and Leviticus 11:10, there is a distinction between
“living” creatures and “swarming/moving” creatures that teem in
the waters. So the logical conclusion can be made that a “living”
creature is one that contains red blood.
There’s much more, but it’s all masturbiblation, picking at words and extracting far more significance from them than is warranted, all to determine that squid actually aren’t alive*. There’s hairsplitting in Genesis, and a silly exegesis of the dietary rules in Leviticus.
What I’d really love to see now, though, is the rhetorical squirming they’d go through when it’s pointed out that human embryos do not develop red blood cells until about the 5th week of development, and therefore the early embryo, by their own definition, is not living. Heh.
One bit of good news: this definition greatly simplifies the project to create an army of death-ray-wielding undead squid-men.
