Guided by the Texas Department of Wildlife and Fisheries' experts it was an easy find. The Golden Orb is one of many mollusks that are diminishing in numbers and may well promise to go the way so many other. Of the three members of the Quadruls species know to have existed in the San Marcos only two are left. The shown location is not the actual site but one of the public access points to the river.
