Abstract:
A Serpulidaepolychaetae, Spirobranchuskraussii, was newly recorded in the Persian Gulf, Iran. It is the first record of Serpulidae species in Iran. Serpulidaeforms dense aggregations in rocky shores in Bandar Abbas. This research investigated the biological structure and the effect of temperature on embryonic stages of S. kraussii. Sampling was conducted with a quadrant of 10×10 cm2, in rocky shores from January to May. The largest specimen of S. kraussiimeasured to a total body length of 36.4 mm, body width of 2.3 mm, total tube length of 48mm, and body wet weight of 0.11mg. Outer surface of tube is white and triangular in cross-section, inner surface colored blue or violet. Body color in ventral surface of thorax is dark violet, blue and pink. The sex ratio in S. kraussii was 1:2 and 1:0.81 in winter and spring respectively. Length-weight relationship was exponential and growth seems to be allometric for S. kraussii. A linear relationship was found between total length and other parameters. Correlation coefficients between parameters were positive and significant (p
