Coffee is one specific species of a bean, roasted, and brewed with varying amounts of hot water, milk, chocolate, and maybe a few other ingredients.<p>There are endless species of fish, with wildly different tastes (salmon, vs tuna, vs tuna belly, vs monkfish liver, vs catfish, don&#x27;t tell me you can&#x27;t taste a difference).  In addition to fish, there are crustaceans (crab, shrimp, lobster, etc), mollusks (oyster, clam, squid, octopus, cuttlefish), and probably other major animal types I&#x27;m omitting.<p>The comparison is not adequate, sushi is inherently more diverse than coffee.
