This week: pyrosomes!

Pyrosomes are pretty cool!  I recently saw many on the research cruise I was on in August off the coast of Oregon.  Using the cameras on the remotely operated vehicle onboard the ship (think underwater robot), we got a sneak peak at pyrosomes in action as the vehicle descended through the water column to the seafloor.  Their bioluminescence was beautiful to watch, especially in the middle of the ocean with no other lights in sight.  Have you seen bioluminescence?
