My oldest went to Red Lobster in High School and paid for a live Lobster and then brought it home, alive and we had to keep it going....it was more like a crawfish...but it lived for quite some time. I think it's because our local Super Market (King Soopers) had a tank of live lobsters (with rubber bands around their claws) - 37 years ago I would put my hand on the outside of the tank and say "poor Lobs"...and I ate one today, I'm not proud of myself. No wonder my stomach is effed up!
They are just big saltwater crawdads, and crawdads taste good too! I have not had one for a while.
