Marine Ribbon Worm Facts
- Marine Ribbon Worm serves as the collective common name for any of the roughly 600 species of ocean-dwelling invertebrates in the phylum Nemertea.
- Every known species in this rather impressive phylum moves slowly and most prefer to live on the ocean floor while a few live in the open ocean.
- All known members of this phylum possess an oversized proboscis and consequently, men sometimes refer to them as proboscis’s worms.
- Despite its tiny body width, some individuals actually grow to rather astonishing lengths.
- In fact, a member of this phylum currently holds the record for being the longest known creature to ever known to exist.
Marine Ribbon Worm Physical Characteristics
The different species of the Marine Ribbon Worm attain rather widely varying sizes. Nearly all of these grow extremely thin in relation to the body length hence the source of the common name.
Most measure less than 8 in (20 cm) in length, yet a few species attain enormous lengths.
One exceptional specimen was 177 ft (54 m) long which made it the longest creature ever known.
Most varieties display various combinations of red, green, orange, and yellow in color. The internal organs remain rather primitive.
Given the vast number of different types in the phylum, color patterns tend to vary widely. However, brighter colors tend to predominate.
Marine Ribbon Worm Distribution, Habitat, and Ecology
Various species comprising this phylum live in every ocean on earth. While not every member of the phylum constitutes a Marine Ribbon Worm, the great majority do.
Most commonly, the members of this rather fascinating group of creatures live on the ocean floor.
Typically, individuals either bury themselves in the sand or mud or hide between rocks.
Most species of this worm appear to be carnivorous and typically prey upon a variety of clams, annelids, and crustaceans.
However, a few species appear feed as filter feeders.
