The skin, however, will still blister and turn greenish black. And if the body is floating in water less than 70 degrees Fahrenheit (21 degrees Celsius) for about three weeks, the tissues turn into a soapy fatty acid known as " grave wax" that halts bacterial growth. On the open ocean, however, flies and other insects are largely absent. Vultures, dogs or other large mammals may also take pieces of the decomposing flesh, sometimes reducing the corpse into a skeleton in under two weeks. Shortly after death, flies and other insects consume the soft tissue. On land, bacteria and other microbes in the body will rapidly multiply and break down the soft tissue.
