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.
In the deep ocean, where resources are often scarce, organisms are in fierce competition for food. During our dive in Washington Canyon, we observed several crabs fight over a recently caught squid.

While exploring Phoenix Canyon, scientists came across this eel who had recently captured a squid. After a struggle on the seafloor, the eel swam into the sediment cloud, the squid held firmly in its jaws.

During exploration of Retriever Seamount, scientists imaged a cup coral that had recently captured a small jellyfish for its next meal. These deep-sea corals usually eat whatever falls from above or comes close enough for them to capture with their tentacles.
