The longest species of worm of any kind is the bootlace worm (Lineus longissimus), a species of nemertean or ribbon worm, inhabiting shallow waters of the North Sea. In 1864, following a severe storm at St Andrews in Fife, UK, a record-breaking specimen was washed ashore, and was found to measure over 55 m (180 ft) long.
