The longest animal in the world is … a worm. It is the Ribbon Worm, belongs to the phylum Nemertea, also known as Lineus longissimus. Lineus can grow up to a length of 100 feet or 30 metres surpassing a blue whale. Their body is brown with lighter stripes. Scientists believe it can actually reach 200 feet or 60 metres if it stretches it’s body.
It is found under boulders at low tide along the North Sea and has been reported to exceed 150 feet in length and commonly exceeds 15 feet. Lineus longissimus can be found on sandy shores, muddy shores, and in tide pools.Their body is brown with lighter stripes.
Exact length of nemerteans can’t be measured because nemerteans are capable of stretching from 2 to more than 10 times their most contracted length.
So 60 metres is not the limit!
