抄録
The tanaidid species Zeuxo ezoensis Okamoto et al., 2020 has previously been reported from among brown and red algae in the intertidal zone at Oshoro and on Rishiri, Rebun and Okushiri Islands, Hokkaido, Japan. Here we first report Z. ezoensis from an artificial environment, an open-air pool in the Rishiri Sea Urchin Seed Production Center on Rishiri Island. The pool is used for the temporary storage of laminarian algae, and tanaidaceans may have entered with the algae. Our sample collected in October 2020 contained famles with marsupium scars, indicating that Z. ezoensis reproduces in the pool. The sample also contained mail individuals that are larger than the largest male collected in fall 2011 at Oshoro. This occurrence of large males in the pool may be related to the absence of fish, which are known to prey on Z. ezoensis.
