White Ragworm (N. Diversicolor)
Ragworms are predators. They have very strong jaws. They have many legs and reproduce in the spring. These type of worms are used a lot for fishing. Ragworms eat by scavenging and by feeding on decomposed matter. A female ragworm can contain at least one million eggs! They can have a lifespan of one to three years. They have long, flattened bodies, two pairs of antennae, and four eyes. The ragworm evolved in the sea.
The ragworm's circulatory system is very similar to the closed circulatory of an earthworm. However, it has a few differences. Blood still travels through the blood vessels, but the ragworm has more bristles than an earthworm. Bristles are short, stiff hairs. The ragworms also contain more appendages and live in marine environments.
