摘要

: 2018年1月，在日本中东部神奈川县相模湾的日本沿海海域采集了100多只海参幼虫。根据获得的1只幼鱼线粒体16S rRNA基因区序列，经BLAST搜索，遗传距离为0.3%，鉴定为多元硬趾藻(scleroodactyla multipes)。观察了3个月的发育过程，从250µm长到4 mm左右;在这里，它们显示出明显的触须和真皮小骨。本文首次利用立体显微镜、荧光显微镜和扫描电镜对其形态特征进行了详细的描述。这是第一次描述从浮游幼虫到幼鱼的硬趾足科生活史。

First description of developmental processes in Sclerodactyla multipes (Echinodermata: Holothuroidea: Dendrochirotida) from Misaki, Sagami Bay, Japan

: More than 100 individuals of sea cucumber larvae were collected in the Japanese coastal sea of Moroiso, Sagami Bay, Kanagawa Prefecture, central-eastern Japan, in January 2018. Based on an obtained sequence of mitochondrial 16S rRNA gene region of one juvenile, it was identiﬁed as Sclerodactyla multipes by BLAST search with 0.3% genetic distance. The developmental process of the S. multipes was observed for three months, in which time, they grew from 250 µ m to about 4 mm in length; here they showed distinct tentacles and dermal ossicles. Detailed morphological features of this species were described based on stereomicroscopic, ﬂuorescence and SEM observations for the ﬁrst time. This is the ﬁrst description of life history through planktonic larva to juveniles in the family Sclerodactylidae.

期刊介绍： Plankton and Benthos Research is a peer-reviewed journal publishing quarterly original papers, reviews and notes dealing with any aspect of the biology and ecology of planktonic and benthic organisms and their interactions with the environment in any aquatic system, and is open to all scientists around the world. Submission of a paper is held to imply that it represents an original contribution not previously published and that it is not being considered elsewhere.
