Sharks lined up at a fish market. "Several years ago, visiting the Dubai Fish market on any day, you would find hundreds of sharks - species I could only dream of encountering underwater - lined-up, lifeless, waiting to be auctioned. Endangered sharks like this smooth hammerhead were often traded from Oman to the UAE, their fins destined to the Asian markets. After their listing on CITES in 2014 much of this trade has become regulated and the UAE has fully protected the species, so these scenes are hopefully a memory from the past in Dubai, but remain a crude reality in many countries where protection is not yet in place."
