For women, who throw a weight of 20 lb, the world record is 24.57 m (80'07Â½) (outdoor) set by Brittany Riley of Southern Illinois University on January 27, 2007 and 25.56 m (indoor), also by Riley, on March 10, 2007. The weight throw event has had an enduring history in American track and field.
Detritus, mud, plankton, phytoplankton, and soft-bodied  invertebrates are what ragworms eat.    Specifically, the ragworm (Nereididae family) has  many legs with whi â¦ ch to move through mud in search of dead and live  animals and plants. It has strong jaws with which to prey upon  invertebrates.
During wet seasons when there is a lot of grass this is what they usually eat. They find their food in the dry season by digging. They use their snouts and their feet to dig, and they sometimes kneel down on their wrists to get lower. They have pads on their wrists to prevent them from damage. The food they are digging for includes roots, bulbs and rhizomes.
