world's smallest animal - world's smallest animal...
After a little research i've come with this result:Scientists in San Diego have described the earth's smallest, lightest animal with a backbone. H.J. Walker of Scripps Institution of Oceanography at the University of California, San Diego, and William Watson of the Southwest Fisheries Science Center, National Marine Fisheries Service, in La Jolla have identified the miniscule "stout infantfish," a new species no longer than the width of a pencil.
