picture info	Nemerteans Nemertea is a phylum of animals also known as ribbon worms or proboscis worms, consisting of 1300 known species. Most ribbon worms are very slim, usually only a few millimeters wide, although a few have relatively short but wide bodies. Many have patterns of yellow, orange, red and green coloration. The foregut, stomach and intestine run a little below the midline of the body, the anus is at the tip of the tail, and the mouth is under the front. A little above the gut is the rhynchocoel, a cavity which mostly runs above the midline and ends a little short of the rear of the body. All species have a proboscis which lies in the rhynchocoel when inactive but everts to emerge just above the mouth to capture the animal's prey with venom. A highly extensible muscle in the back of the rhynchocoel pulls the proboscis in when an attack ends. A few species with stubby bodies filter feed and have suckers at the front and back ends, with which they attach to a host. The brain is a ring ...

	Tubulanidae Tubulanidae is a family of primitive nemertean worms in the order Palaeonemertea. Characteristics Worms in this family have slightly flattened, rounded heads and approximately cylindrical bodies. Apart from the genera, '' Callinera'' and '' Carinina'', worms in this family have paired cerebral sensory organs located on either side of the constriction where the head joins the body. Some species are red or brown, often with distinctive white bands or longitudinal stripes, but others are small and so translucent that their cerebral organs can be seen through the skin.

	Palaeonemertea Palaeonemertea is a class of primitive nemertean worm. It may be para- or polyphyletic, consisting of three to five clades and totalling about 100 species. These worms have several apparently simple features and, as their name suggests, they are often considered to be the most primitive nemerteans. The primary body-wall musculature consists of an outer circular layer overlying a longitudinal layer. The group includes genera such as '' Cephalothrix'' in which the nerve cords are inside the body-wall longitudinal muscle, and ''Tubulanus ''Tubulanus'' is a genus of primitive nemertean worms in the order Palaeonemertea. Species The World Register of Marine Species includes the following species in the genus: * '' Tubulanus albocinctus'' (Coe, 1904) * '' Tubulanus annulatus'' (Mo ...'', in which the nerve cords are between the outer circular muscle and the epidermis. Tubulanids are commonly encountered in rocky areas of intertidal zones in the northern hemisphere. They are often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
