The Echiura, or spoon worms, have a pear shaped, non-segmented body and a large and non-retractile proboscis. In the anterior ventral region there is a pair of setae or hooks. They live in burrows in sand, mud, corals and coral crevices. Some species are found inside the tests of dead sand dollars and between the shells of dead bivalves. There is strong evidence that echiurans are in fact modified annelids.
