Which of the following is a characteristic of polychaete worms?

The known species of polychaetes share only a few characteristics.

It’s these bristles that give the worms their name: “polychaete” is Greek for “with much hair.”

What is the most distinctive feature of ribbon worms?

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.

Which of these organisms exhibits all the characteristics of chordates as an adult?

Tiny food particles are trapped in mucus and moved through the gut (housed in the coelom). There are many beautiful species! The subphylum CEPHALOCHORDATA is named for the fact that the notochord is ALSO in the tail. This small group of species is the only group which exhibit all 4 chordate characteristics as adults.

Which is a characteristic of ribbon worms and flatworms?

Ribbon worms differ from the flatworms by having a digestive tract with separate mouth and anus and possession of an eversible proboscis contained in a fluid-filled rhynchocoel located dorsal to the gut (Sundberg and Gibson 2008).

What do ribbon worms and flatworms have in common?

The affinities of the nemerteans may lie with the flatworms, although molecular evidence generally fails to support this view; both groups have similar types of embryonic development and the same basic body plan. Unlike the flatworms, however, the ribbon worms have a complete gut and a circulatory system.

What is the most important feature of ribbon?

The typical structure of a ribbon includes large, tabbed toolbars, filled with graphical buttons and other graphical control elements, grouped by functionality. Such ribbons use tabs to expose different sets of controls, eliminating the need for numerous parallel toolbars.

What is the difference between Errantia and Sedentaria?

What are the characteristics of oligochaeta?

Oligochaetes, which range in length from a few millimetres (a fraction of an inch) to more than 3 m (10 feet), are notable for the absence of a head and parapodia, the flat, lobelike outgrowths used by many polychaete annelids (class Polychaeta) for locomotion. They have few setae, or bristles, on the body.
