Polychaetes Differ From Other Annelids Because Polychaetes

The polyphyletic group of morphologically similar worm borings refers especially to cavities produced by polychaete annelids and sipunculans which according to the literature are mainly cosmopolitan in distribution but are more likely to represent suites of cryptic species. They are dioecious and multi-segmented.

C have a clitellum used for reproductive purposes. Tubicolous annelids are capable of secreting mucous or other adhesive substance to which sand and shell particles get attached and make the tube strong eg. Polychaetes differ from other annelids because polychaetes A lack any head or specialized sense organs.

The polychaetes differ from other annelids by having a well-developed head that often bears the eyes antennae and sensory palps and is called a ________ or first segment. Polychaetes bristleworms are marine annelids with parapodia bearing numerous setae in distinct fascicles.

B have paired parapodia on most segments. Polychaetes are morphologically distinct from oligochaetes by having muscular appendage-like structures parapodia along the length of the body. Polychaetes and oligochaetes are two subclasses of phylum Annelida.

The literature reports higher polychaete diversity in tropical freshwaters but the reason for this is not clear. A lack any head or specialized sense organs. C have a clitellum used for reproductive purposes.

Lack any head or specialized sense organs B. The sense organs in polychaetes are more highly developed than in oligochaetes. Typically polychaetes exclusively live in marine habitats.

They have simple exit ducts from the gonads. They have many setae usually arranged in bundles on the parapodia. Most of them live in soft or rocky environment on sea floor from intertidal to depth.

Pectinaria Owenia Diopatra Clymenella Sabella. Many sedentary and tubecolous polychaetes eg. Have paired parapodia on most segments C.

E All of the choices are correct. - Annelida 1 Polychaeta 1 Oligochaeta 1 Hirudinea - Crustacea 2 Cladocera 2 Copepoda 3 Ostracoda 1 Amphipoda 1 Decapoda. Meanwhile oligochaetes are another subclass of annelids having few bristles but no parapodia.

Polychaetes like other members of the Annelida have two pre-segmental regions the prostomium and peristomium a segmented trunk metastomium and a post-segmental pygidium. 10 Polychaetes crawl by means of leg-like _____ which also serve in respiration. Explore answers and all related questions.

Tubicolous polychaetes Tubicolous polychaetes live permanently inside the tubes made of mud shell or sand grains parchment or calcium carbonate. B have paired parapodia on most segments. With no significant differences between controls and treatments for the most representative taxa.

Polychaetes differ from other annelids in having a well differentiated head with specialized sense organs and no clitellum. C have a clitellum used for reproductive purposes. The nuchal organs a pair of chemosensory structures on the posterolateral margin of the prostomium are apparently the only synapomorphy of the Polychaeta that distinguishes.

Polychaetes differ from other annelids because polychaetes A. Polychaetes are a subclass of annelids having many bristles arranged in parapodia. And no clitellum Figure 17-3.

Polychaetes differ from other annelids because polychaetes-lack any head or specialized sense organs-have paired parapodia on most segments-have a clitellum used for reproductive purposes-lack setae-All of the choices are correct. The vast majority of the more than 8000 known species of polychaete worms are marine. Prostomium The paddlelike appendages that characterize the polychaetes are called parapodia The segment of the annelids that bears the jaws is called the peristomium.

The many common names reflect the wide array of body forms found in this group unlike the earthworms and leeches. They have many setae usually arranged in bundles on the parapodia. Polychaetes are known by many names.

Polychaetes differ from other annelids because polychaetes Lack any head or specialized sense organs Have paired parapodia on most segments Have a clitellum used for reproductive purposes Lack setae All of the choices are correct Have paired parapodia on most segments The cocoon in the earthworm is produced by the Clitellum Prostomium. All of the choices are correct not correct. PEP has also been characterized from the whole body of a marine polychaete Perinereis vancaurica using an immunoblot assay 3Two GGNG peptides TEP-1 and TEP-2 were isolated from the marine snail Thais clavigera with a bioassay using an isolated preparation of esophagus 4Unlike other GGNG peptides these molluskan peptides have two Trp residues within the ring.

Lugworms clam worms bristleworms fire worms palolo worms sea mice featherduster worms etc but all possess an array of bristles on their many leg-like parapodia-- the name polychaete in fact means many bristles. One of the strangest and best-studied polychaete life histories is that of the genus Eunice.
