The long nemertine ( Lineus longissimus ) belongs to the line worms (Nemertea). It is a carnivorous sea creature. It can reach a length of more than 30 meters, making it one of the longest animals on earth.
features
The body diameter is 5 to 10 mm. Lengths of five to ten meters are considered normal, but lengths up to 30 meters have also been observed more frequently. A 55-meter-long specimen is even reported found after a storm on the coast of St Andrews , Scotland, in 1864 . Its color is dark brown with light brown vertical stripes.
distribution
Distribution areas are the brackish water zones of the seas of northwest Europe, i.e. in the north-east Atlantic around the British Isles and along the Norwegian coast to the North and Baltic Seas . Lineus longissimus lives in shallow water zones on hard ground between stones and algae, but it can also be found on sandy or muddy ground or in tide pools.
Systematics
Lineus longissimus was first described in 1770 by the Norwegian naturalist Johan Ernst Gunnerus as Ascaris longissima . Lineus longissimus was confirmed as a separate species in 1995, and also in 1997.
