Lobster Grey then Lobster Red...why ?
« on: 22/08/2007 13:33:25 »
Couldn't decide if this would be in chemistry or Environmental..so I stuck it here.


Dear Lobster Lovers,

Why do lobsters turn from this:


BEFORE:



to this ?

AFTER



.....after they've enjoyed a bath  or sauna at someone else's behest !

Prawns also turn colour too !..are they blushing ?

It's camouflage. The lobster has checked out the area, seen no rabbits, so decided to make like a carrot.

Believe it or not, I know this one.  After feasting on a delicious lobster dinner the night before (for a king's ransom), I asked this question to one of the researchers while visiting the New England Aquarium in Boston- apparantly cooking destroys all the pigments except the red pigment in the exoskeleton.  While alive, the brown and green pigments are dominant.

I can see how that would work...I've always wanted to look like a  delinquent cabbage....instead my mentality does the impression !!

Thats interesting I wonder what makes the red so tough that it is not destroyed also?
