When I eat seafood or other things cooked whole (lobsters, octopus, crabs), why can't I identify any organs?

The liver, pancreas and most of the rest of the digestive system become a green goopy delicacy called tomalley when cooked. Most of the other organs you'd expect are there but are small and hard to find.

The lobster brain - technically a supraesophogeal ganglion - is one of the trickiest organs to locate. It is about the size of a grain of rice and far forward near the eyes above the esophagus.

There is a heart but it is small, and there are few arteries or veins. Instead of truly having blood they have a fluid called hemolymph that is not confined to arteries and veins, and they rely on body motion to do most of their pumping. This system is called a (partially) open circulatory system. The thing that looks like a vein in the tails of lobsters and shrimp is an intestine.

Orange granular goop in the tail is eggs (roe) and considered a delicacy, and yellowish-white less-granular goop in the tail is sperm (milt).

Carefully removing the brain and waving it around for other people to see at a fancy restaurant will get you mixed reactions.
