Title

MORPHOLOGY AND BIOLOGICAL CHARACTERISTICS OF POLYCHAETE, STREBLOSPIO GYNOBRANCHIATA, AT NOOR COAST-CASPIAN SEA

Pages

  23-29

Abstract

 Morphology and BIOLOGICAL CHARACTERISTICS of polychaete, STREBLOSPIO GYNOBRANCHIATA, sample from the depth 15 m on the NOOR COAST was investigated seasonally during one year. Morphological results revealed that the color of this worm was faint green, possessing a distinguished head with a pair of eyes, palps, gills and a mouth. The last segment of its body (pygidum) is simple and without any branches. Length and wet weight of this worm varied in different seasons and on average (n=120) the biggest length and the highest wet weight were 8.61±2.4 mm and 225±35 mg in winter and the least length and the wet weight were 5.82±2.35 mm and 180±35mg in spring. Annual average length and wet weight of mature female (n=55) were 8.11±1.24 mm and 237±42 mg, respectively. The number of mature female segments on average was 41±1.3. Study of feeding and habitat revealed that this worm was a deposit feeder and feeding on the surface organic matter. It lives from 2-2.5 cm up on the sediment surface and almost every 3-4 days, because of food limitation and increasing fecal plate, it moves about some centimeters around its residence.
