Pangasius, or Iridescent shark, is one of several species of shark catfish. These fish are not sharks, but rather catfish that bear some resemblance to sharks.
Another name used is "Swai", but this is actually a close relative, not the same fish.
Iridescent shark is a popular fish for eating and lives in rivers and is farmed in the US and especially in Asia.
You might also find it under the name “Panga”, “Basa”, “River Cobbler” and variants on “catfish”. The misleading name “Vietnamese sole” is also found. It's all very confusing...
