Thus, E. mucronata extracellular hemoglobin is the sole oxygen transport molecule m this animal and is very abundant, comprising 19% of the animal's dry wt. It seemed likely, therefore, that this molecule plays an important functional role in the respiratory physiology of this by: Thoracophelia (Annelida, Opheliidae) are burrowing deposit feeders generally found in the mid- to upper intertidal areas of sandy beaches.

Thoracophelia mucronata (Treadwell, ) is found along the west coast of North America, including at Dillon Beach, CA. The potentially large effect on the reduction of food density by a sand-particle AKIO TAMAKI swallowing opheliid polychaete was demonstrated by McConnaughey & Fox (): they estimated that a high-density population of Thoracophelia mucronata processes as much as 21 % of the surface layers of a beach sand by: 8.

A cladistic analysis of spiralian taxa (with special reference to polychaete annelids), based on a suite of adult and larval characters, is used to assess several hypotheses: (1) that the trochophore (in a strict sense) is a plesiomorphic form for the Spiralia; (2) that die stricdy defined trochophore is plesiomorphic for members of the Spiralia such as the by: Abstract.

The digestive tract of Sabellaria alveolata (L.) is partitioned into 4 main regions: oesophagus, gizzard, intestine and rectum. Histoenzymologic study of the repartition of the protease activities along the digestive tract has shown that the proteases are secreted in the anterior intestine, where numerous serous gland cells are by: 5.

Polychaetes are a taxanomic class of segmented da is the phylum for segmented worms and polychaetes are the marine varieties of segmented worms.

These worms were created on the fifth day of creation. Some polychaetes might not even look like worms but they come in all kinds of different shapes and colors and sizes.

Polychaetes can inhabit mostly all marine. Burrowers and borers are ecosystem engineers that alter their physical environments through bioturbation, bioirrigation and bioerosion. The mechanisms of moving through solid substrata by burrowing or boring depend on the mechanical properties of the medium and the size and morphology of the organism.

Interstitial marine meiofaunal worms of the genus Diurodrilus have always been considered part of Annelida, either as basal or derived, though generally with reference to Dinophilidae.
