Lineus longissimusとは 意味・読み方・使い方

The bootlace worm (Lineus longissimus) is in the phylum Nemertea or ribbon worms. It is one of the longest animals known, with specimens up to 30 metres (98 ft) long being reported. They may grow as long as 60 metres (200 ft), which would make it the longest animal in the world. They are however usually only 5 to 10 millimetres (0.20 to 0.39 in) in width. The body is brown with lighter (longitudinal) stripes. It is the most common nemertean found along the coasts of Britain. When handled it produces large amounts of thick mucus with a faint pungent smell. A specimen washed ashore in the aftermath of a severe storm by St Andrews, Scotland, in 1864, had a length of more than 55 metres (180 ft), longer than the longest known Lion's mane jellyfish, the animal which is often considered to be the longest in the world. However records of extreme length should be taken with caution, because the bodies of nemerteans are flexible and can easily stretch to much more than their usual length.
