The majority of enoplan ribbon worms are marine and benthic, but there are approximately 100 named and described species of pelagic nemerteans. These creatures inhabit the water column of the world oceans, commonly found at depths of between a few hundred feet and several thousand feet, and they are most abundant at 2,130 to 8,200 ft (625 to ...
Lineus sanguineus, the banded nemertean [2] or social lineus, [1] is a species of nemertean ribbon worm in the family Lineidae.

It is possible that its bright red colouration is aposemetic, giving warning that this particular ribbon worm is toxic or unpalatable. [6]
