Dolphins face many challenges in our oceans.  They suffer negative effects from oil spills, can drown from entanglement in fishing gear or accidentally ingest marine litter, especially plastics.  They are hit by boats and their propellers and are affected by marine mining and seismic surveys. Fish, their main diet, have also declined in many areas due to changing ocean temperatures and currents, and overfishing by humans.

"Our NMMF team feels strongly about protecting dolphins in our oceans," emphasized Dr. Cynthia Smith, NMMF Executive Director.   "Identifying and following individual animals is essential to researchers worldwide who study dolphins' survival and reproductive rates, population size, and other parameters important for effective conservation actions and finFindR will help them do that "
