Why is the lobster blue?

crustacyanin?

because of his immunity to frost damage.

Over (under?) expression of a certain protine.

>>8263566

Because if he was green he would die.

shiny

reddit-tier? then why are you here?

>>8263566
Lacks correct expression of a certain protein that has something to do with adding copper, or some manner of pigmentation. Occasionally you'll find a crustacean like that.

Crayfish have it happen too. I found one in Vermont, in a lake way out in the woods with an old dock long abandoned. It was just sitting there under the dock. Then it burrowed into the mud.

Curious, what was reddit-tier about his post?
Seemed fine to me.

Thats not even the lyric. Fuck off

Hemocyanin in it's unoxidized state is colorless, and blue in it's oxidized state.

If a lobster is blue, it's blood is still well oxidized. They lose this blue color in oxygen-deprived conditions, or when you cook them as the heat releases the oxygen atoms from the hemocyanin molecules.

That lobster has just been taken out of the water, while the rest have been there for a while.

No, it has nothing to do with the oxidation of their blood. It's about their exoskeleton synthesis.

Report and hide this poster. They go to threads and just spam something semi-related to the thread and make sure to list that website in their post.

The exoskeleton is made by hardening the soft, inner tissue. The hemocyanin, amongst many other molecules, winds up in the exoskeleton. If, inside the exoskeleton, oxidized hemocyanin can't shed oxygen atoms or oxygen-containing functional groups, it will remain blue.

The genetic mutation you speak of surely has something to do with a gene that removes or reduces the hemocyanin within the forming exoskeleton.

because it's depressed

give it a prozac and throw it back in the water

not sure how exoskeleton coloring is determined but Id guess either albinism or something to deal with light penetration at certain depths causing different coloration

>>8263566
Copper.

>>8263566
SHINY

at least he's not bipolar

GIVE HIM LITHIUM.
HE'S BEING DIFFERENT.
HE JUST WANTS ATTENTION.

>>8263566
Don't lobsters have blue exoskeletons right after they shed their last exoskeleton?

>>8263566
Because it reflects light from 420nm to 490nm

>>8263566
because someone painted it

>>8263566
Which one (color blind)

>>8263566
Because he is very sad. He is a very sad lobster. Quite blue. Quite blue, indeed.
