About The Homepage Video

The larva of a marine snail (Crepidula fornicata) generates powerful currents in the water around itself as it swims in search of food. Inserting brightly colored particles into the water near the animal allows these currents to be easily visualized using time-lapse photography, resulting in two large vortices becoming visible near the animal. The Prakash Lab’s members William Gilpin, Vivek Prakash and Manu Prakash introduce a general visualization technique to identify large-scale coherent patterns generated by the motions of organisms at a variety of scales, a potentially new technique for analyzing locomotion, flocking and swimming without the need for more intensive computational tools.
