Predation in the Deep Sea

October 6, 2014

In this log, we'll be sharing video of different examples of deep-sea predation encountered over the course of the Deepwater Backyard expedition. While these videos definitely rank high on the "cool" factor, being able to witness these kinds of predation events live offers scientists unique glimpses into the lives and behaviors of critters of the deep.
