The giant tun shell, Tonna galea, is found in the Caribbean, Atlantic, Mediterranean and Indo-Pacific oceans.  Tonna galea shells or Tun shells are thinner and usually roomier than helmet shells.  Tonna galea shells are almost exclusively tropical and prefer deeper water and feed mainly on fish, sea urchins and crustaceans.  We carry tonna from 3 inches up to 8 inches in length.  These brown pretty shells are light weight and make perfect homes for hermit crabs and are perfect for coastal home decorating and make a perfect seashell centerpiece for wedding reception tables.  Tonna Cumingi are globosely ovate, thin, inflated, and lightweight with a rounded body whorl.  They feature consists of about seven transversely ribbed whorls featuring linear grooves, a slightly twisted columella, and a simple lip.  A bright fulvous chestnut background, beautifully clouded with distinct brown and white spots or zigzag patterns.  Found across the Indo-Pacific region they inhabits sandy bottoms in tropical marine environments.  Tun shells generally bury themselves in the sand during daylight hours and emerge at night to hunt.
