The bootlace worm feeding on dead annelids

The specimen of L. longissimus in the video had a length near 2 meters and was collected by dredging the fjords near Bergen, on the West coast of Norway. And yes, it eats four whole annelid worms in a row.

Nemerteans are slender worms that glide through the bottom of the oceans and seashores worldwide. One particular species living in the North Sea—Lineus longissimus, the black line-worm or bootlace worm—is considered to be one of the longest animals on Earth. Individuals can grow up to 30 meters! One Scottish specimen might have been 55 meters long (McIntosh 1873-1874, Carwardine 1995), but these estimates are tricky!
