Electropositive shark repellent Atlantic longlining vessels in 2008. As expected, teleosts (bony fish) are not repelled by the electropositive metal’s cation liberation in seawater. This is because teleosts lack the ampullae of Lorenzini. Teleost response was confirmed using captive Cobia ("Rachycentron canadum") and Pacific halibut ("Hippoglossus stenolepis"). In July 2008 swordfish ("Xiphias gladius") catch was reported on experimental hooks treated with electropositive metal. As with all shark repellents, 100% effectiveness will not be achieved with electropositive metals. The metals are particularly effective when the shark is relying on its electrosense. It is likely that electropositive metals are ineffective for deliberately stimulated (chummed) sharks,
The World Is Flat Science, wrote another critical review of Friedman's book called "The World Is Round". In it, Gray confirms Friedman's assertion that globalization is making the world more interconnected and, in some parts, richer but disputes the notion that globalization makes the world more peaceful or freer. Gray also declares, "least of all does it make it flat". Geographers on the whole have been particularly critical of Friedman's writings, views influenced by the large body of work within their field demonstrating the uneven nature of globalization, the strong influence place still has on people's lives, and the dependent relationships that have been
