The MU DU BONG freighter was heading to the port of Tuxpan when it hit 250 coral reef colonies in the Gulf of Mexico on July 14, the environmental protection prosecutor's office said yesterday.
One of the habitats included Elkhorn coral, or Acropora palmata, an at-risk reef-building species shaped like elk antlers, the agency said in a statement.
Seven other species were struck by the vessel, including coralline rock on a protected list.
Rescuers removed the 6,500-tonne ship on Saturday, using underwater cameras, buoys and other special equipment.
The environmental prosecutor's office said the North Korean embassy has pledged to reimburse the costs of the rescue.
