Albinism in the sea cucumber Apostichopus japonicus (Selenka) may be a significant biomarker that can be used to obtain information about behaviors and growth of this species. The goal of this study was to compare the behaviors and growth rate between albino and normal A. japonicus. Total light intensity and specific growth rate were used as statistical indices. Diverse light intensities were tested in the laboratory and in the field to identify ecological characteristics of albino A. japonicus. Experimental results revealed that: (1) both albino and normal specimens had negative phototaxis; (2) normal A. japonicus were more responsive to intense light than albino species, and the latter could withstand longer periods of exposure to intense light; (3) normal A. japonicus grew faster than albino specimens; and (4) both normal and albino A. japonicus grew faster in natural light than in the other light intensities tested.
