The paddleworm Phyllodoce maculata resembles a small thin ragworm with two rows of black spots. The Dutch think it looks like a diesel train and has named this worm appropriately the 'spotted diesel train worm'. The animal propels itself in unusual jerky movements. It has what looks like a long tongue for sucking out its prey. You don't often find the worm itself, however in the spring the bottle-green one-centimeter large jelly lumps containing its eggs are easily spotted. The eggs are anchored to the bottom and hatch between two days to two weeks (depending upon the temperature).
