The penny beneath the worm is a penny comparing the size of the worm. This is a sample from Lobos Creek 3 and taken here to the lab at Crissy Field Center to identify.
The nematodes ( /ˈnɛmətoʊdz/) or roundworms (phylum Nematoda) are the most diverse phylum of pseudocoelomates, and one of the most diverse of all animals. Nematode species are very difficult to distinguish; over 28,000 have been described, of which over 16,000 are parasitic. The total number of nematode species has been estimated to be about 1,000,000. Unlike cnidarians or flatworms, roundworms have tubular digestive systems with openings at both ends.
