A “Shark’s Eye” View in the Ocean

Scientists have found news ways to gather information about sharks by attaching instruments to their bodies, enabling them to have a “shark’s eye” view in the ocean.  

Scientists Carl Meyer from Hawaii Institute of Marine Biology and Itsumi Nakamura, and Katsufumi Sato from the University of Tokyo have learned many new things about shark’s feeding and movement patterns by attaching data and miniature video loggers onto live sharks.  These loggers even provide them information about behavior, habitat use, and other aspects that were previously unknown about shark ecology.

One of the instruments this team of scientists uses is digested by sharks in order to gain new awareness on these predators feeding habits.  Another instrument this team uses is attached to the sharks in order to provide them with a “shark’s eye” view of the ocean, which help them learn about shark’s behaviors.

According to Carl Meyer, a researcher at the University of Hawaii, the main objective in their research was to find out the major role of sharks in the ocean.  Sharks are an apex predator, or at the top of the food chain, and play a major role in maintaining the health of their ecosystems.  Through this team’s research, many new things can be learned about the ecology of sharks.  In the long run, these new findings can potentially help develop new management strategies for oceanic ecosystems.
