At 9 am we were joined by our guests, a group of Grand Classroom students from Ohio. As we headed out to our tagging location we talked … Continue reading

Shark Tagging with Aventura City of Excellence School

This upside-down view of a Nurse shark's mouth reveals adaptations for hunting crustaceans, a preferred prey group. The barbels near the nostrils are sensory organs and the small but powerful mouth is filled with tiny teeth, all designed to pulverize the hard shells of crabs and lobsters.

by Emily Rose Nelson, RJD student After collecting gear from RSMAS I met up with the rest of the team at the dock of divers paradise. We had a great crew on board and everyone was excited to get out there. Our guests for the day, students from the Aventura City of Excellence School, made their way on board and immediately I could feel their excitement. There definitely was something in the air telling me it was going to be a great day on the water. We were fishing at a sight our team has nicknamed “Sandbar Palace.” It is … Continue reading
