Carnivorous flatfish eat a variety of fish, crabs, mollusks, and invertebrates. Flatfishes are said to have evolved to reside at the bottom of bodies of water and have both eyes on one side of their heads in order to ambush prey. I consumed flatfish sushi last Sunday. They make their sushi with delectable, top-notch, hand-selected seafood, including premium yellowfin tuna, outstanding Scottish salmon, yellowtail, striped bass, eel, fluke, and other species. They always use the freshest fish as a base. They have put a lot of effort into getting fantastic sushi to you and delivering it to your house.
