What order is Nemertea?
Taxonomy of the Nemertea was formerly straight forward, as there are only two classes: Enopla and Anopla. The Class Enopla includes two orders (Bdellonemertea and Hoplonemertea) with about 650 species that have a proboscis usually armed with stylets and a mouth that opens in front of the brain.

Is the ribbon worm real?
Ribbon worms, or nemerteans, are a group of very unusual worms related to mollusks and annelids. Most ribbon worms live in the ocean, and some can grow to over 100 feet long, but are usually much less than an inch wide. Some species live on land or in freshwater. Unlike annelids, ribbon worms are not segmented.
How do Nemertea swim?
Most nemerteans use their external cilia to glide on surfaces on a trail of slime, some of which is produced by glands in the head. Larger species use muscular waves to crawl, and some aquatic species swim by dorso-ventral undulations.
Does Nemertea have brain?
The main components of the nemertean nervous system are the central nervous system consisting of a brain and nerve cords, the peripheral nervous system that includes nerves and plexus, and finally the sensory structures.
Do Nemertea have eyes?
The nervous system includes a brain and several nerve cords; nemerteans also have pigment-cup eyes, ranging from two to 250 such eyes depending on the species (Smith 2008).
Do blood worms puke?
A defining characteristic of ribbon worms is the presence of a proboscis — a unique muscular structure inside the worm’s body. When attacking prey, they compress their bodies to push out the proboscis like the finger of a latex glove turned inside-out. So that thing isn’t vomiting it’s attacking!
