The Giant Pangasius, or Paroon Shark, is a huge fish inhabiting the Mekong River Basin in South East Asia. It can reach an incredible length of 3 metres! It is not a shark, but rather a species of whisker-less catfish. It is a migratory fish and lays its eggs just before the monsoon season. It has a perfectly streamlined body with an elegant dorsal fin. The natural population has declined drastically over the last couple of decades as a result of overfishing. This has made the remaining Giant Pangasius populations severely fragmented and critically endangered.
