In 2009, Oregon State University researchers found shrimp, crab, limpets and barnacles living around a highly active volcano near Guam. Pacific Sleeper sharks are found in the North Pacific from Japan to Mexico. They’re considered non-aggressive and live really deep, so they’re often difficult to see.
