| Abstract: | I report predation of the tanaidacean crustacean Zeuxo ezoensis OKAMOTO et al., 2020 by a captive individual of Haliclystus tenuis KISHINOUYE, 1910 collected from algae in Oshoro Bay, Otaru, Hokkaido, Japan. The behavioral sequence was as follows. Immediately after Z. ezoensis touched the tentacles of H. tenuis, the latter rapidly folded its arms inward and trapped Z. ezoensis inside the calyx. The tanaidacean was digested by six hours after ingestion, except for the exoskeleton, which was ejected from the calyx eight hours after ingestion. Although no tanaidacean has previously been reported as prey for Staurozoa, Z. ezoensis is abundant on algae inhabited by H. tenuis in Oshoro Bay and would be exposed to predation by H. tenuis in the wild. |
