Bocas de Ceniza refers to the mouth of the Magdalena River as it reaches the Caribbean Sea in northeast Colombia. It literally translates to “ash mouth” and this name stems from ashy color of its water. The delta of the Magdalena River is one of the most important ecosystems in the Colombian Caribbean Sea. Its waters serve as a transition zone between continental and marine waters and play an important role in the productivity of coastal tropical regions. They provide refuge and breeding grounds to the innumerable marine species that inhabit the region and are now economically exploited by humans. Bocas de Ceniza in Colombia also contains a great degree of biodiversity that sustains food chains of both marine life and coastal terrestrial life.
