Abstract
: 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.
