| 摘 要： | 本文观察了太平深海带鱼早期发育形态,主要特征是背鳍第一棘延长呈鞭状,向后可达体长的1/2以后,随着鱼体的长大,延长的鳍棘退化。到后期仔鱼,腹鳍和臀鳍分别生有刺和棘,形状尖利。发育到稚鱼期臀鳍第二棘长大,似蝉翼状。随着鱼体长成幼鱼时,腹鳍刺和臀鳍棘相继退化。

| Abstract: | The present paper reports the observation of the early stages of Benthodesmus elongatus pacificus. The important morphological characters is that 1st dorsal fin spine developes and extends to the posterior of anus. Which is about 1/2 of the body length, at the earlier stage and disappers with the growth of the fish. At the postlarva stage, the pelivie spines and the 2 anal fin spines appear. At the Juvenile stage, the second anal spine, in the form of Cicada wing has spinules along the edges. At the final stage, the pelvic spines and the anal spines disapper. |
