ELI5: Why do seafood meats taste so noticeably different from land-based meats?

I don't even understand enough about this situation to describe it adequately.  There's a vividly recognizable flavor to shrimp, crab, lobster, fish, etc. that just isn't there in chicken, beef, etc. - what causes it?  What does it mean?

Those animals are entirely different taxa and are the products of a hugely different environment, spending their existences in salt water. They contain high amounts of iodine and other minerals compared to land animals. Their musculature evolved for environments with very low amounts of gravity.
