Meet Bob, the basket star, a close relative of star fish, sea cucumbers and sand dollars. This guy, like a star fish has 5 point radial symmetry, but then unlike starfish, his tentacles subdivide repeatedly like a fractal. Underwater, Bob likes to hang out on rock pinnacles, and wave his fractal arms around to catch any food that is flowing by, and put it in its mouth.

We have beein using the Puma AUV as a scout for the submarines. Each day we send the AUV to collect thousands of images of the seafloor, and use ROST based topic modeling to identify interesting locations for further exploration through the submarine.
Today was my first submarine dive. We dove to about 300 meters, near Hannibal sea-mount, off the coast of Panama. I was accompanied by WHOI biologist Vicke Starczak, who enthusiastically answered my never ending stream of questions about deep-sea life. We collected several biological samples including star fish, crabs, sea-urchins, and sea-cucumbers, and brought them back for further analysis. The jellyfish of the deep sea are amazing. Many of them glow blue and green when they bump into the sub. Also saw many Siphonophores, which I think are amazing animals/superorganisms/whatever you want to call them. I learned that although they look like a single animal, they are actually a colony of many different animals, living together and behaving as a single creature. The famous Portuguese Man o' War is probably the most famous member of this family fo organisms.
In terms of robotics, I see autonomous sampling, especially in the context of marine environments, as a promising research direction with much work to be done. Many different problems need to be solved to be able to build such robots. For example: recognizing habitats and animal species; computing utility of the given sample given finitie future opportunities to resample; and AUV and actuator control.
