For the first time, MIT engineers and colleagues have observed the initiation of a mass gathering and subsequent migration of hundreds of millions of animals -- in this case, fish. The work, conducted using a novel imaging technique, "provides information essential to the conservation of marine ecosystems that vast oceanic fish shoals inhabit," the team writes in the March 27 issue of Science. It also confirms theories about the behavior of large groups of animals in general. (source: web.mit.edu)
