相模湾のスナホリガニ類の生態とハマスナホリガニHippa truuncatifrons (MIERS)(スナホリガニ科・十脚目・甲殻綱)の後期発生について Some Biological Observations of the Mole Crabs (Hippidae, Anomura, Decapoda, Crustacea) in Sagami Bay and the Complete Larval Development of Hippa truncatifrons (MIERS) 加藤, 隆 鈴木, 博 application/pdf According to MIYAKE (1978, 1982), there have been three species of the mole crabs, Hippa adactyla FABRICIUS, H. truncatifrons (MIERS) and H. pacifica (DANA) (Hippidae, Anomura, Decapoda, Crustacea) in the Japanese waters. Only one species, H. adactyla have been known from Sagami Bay. In the course of this study, the latter species, H. truncatifrons and H. pacifica were newly found from Sagami Bay, and H. truncatifrons predominates among the three species throughout the studied areas. In this study, the authors described and illustrated their distribution, variation of the body, colourations, growth rate, and feeding and mating habits. The authors also studies complete larval development of H. truncatifron. The larvae are reared in the laboratory and passed through five zoeal and one glaucothoe stages and reached to the first crab stage. All the larval and the first crab stages are described and illustrated herein, and some brief comparision and discussion with other related species are also given. 横浜国立大学教育学部附属理科教育実習施設 1992-03-27 jpn departmental bulletin paper VoR http://hdl.handle.net/10131/1569 https://ynu.repo.nii.ac.jp/records/1743 AN10398396 横浜国立大学教育学部理科教育実習施設研究報告 8 77 97 https://ynu.repo.nii.ac.jp/record/1743/files/KJ00004479373.pdf application/pdf 1.6 MB 2016-09-15
