The ship was also carrying a container filled with highly poisonous chemicals, including one called phenol.
It's found in resins and household appliances. It can cause muscle weakness, loss of coordination, paralysis and even coma.
The wetland itself is protected by a sandbank, but the beach, which is home to turtles, is now under threat.
There are all sorts of wildlife there from flamingos to crocodiles.
The rescue of the ship can't start till the fire's put out.
