Ragworms : Hediste diversicolor
Most ragworms live in salt water or fresh water land habitats, but there are a few exceptions. This means that they live near the water, but not exactly in them. They usually burrow underground and move under the sand to transport themselves. Each ragworm has more than one hundred segments by the time they are fully grown. Each segment has a pair of crawlers and a pair of swimming legs. The front segment consists of a head with four eyes and two antennae. Ragworms are omnivores and predators. They eat tiny invertebrates, mud, detritus, phytoplankton and plankton.
Ragworms get their food into their system by using a net-like mouth or using their jaws to eat at their food. They have a direct path from the mouth to the anus, without a stoppage in a heart or anything of that sort. The food goes through the mouth and into the esophagus where it immediately goes into the intestine. Nutrients and the like are passed around to the needed areas of the worm, and then the waste is passed on to the anus. The anus releases the extra waste that is not needed anymore.
