8 Environmental Study

9 Río Mameyes This River travels 15.6 mi 2 from El Yunque (Rio Grande, origin) and Luquillo. One of the ravines (quebradas) that is connected and nourishes this water body Cascada La Coca, which we will mention later on as one of our stops. But is main water current comes from el Río La Mina.

10 Río Mameyes Our main focus was to find organisms in the rocky river, in order to know if it has habitable conditions. Two students, Abneill Alicea and Aníbal Tornés, were able to find snails that were alive, sleeping, or dead. From the three snails that were obtained one was moving and two were not.
