| Abstract: | On December 3rd, 2012, a male adult fish was captured near the shore of the Penglai waters in Bohai Sea Strait. The fish had smooth and naked skin. The body length was 34 cm, and withers height was 18 cm, and head length was 12.5 cm andtrunk width was 4.5 cm. The body length was 1.9 times the withers height and 2.7 times the head length. Tubular lateral lines passed centrally through the lateral body, and curved in the first half and became straight in the rear half. Both sides of dorsal fin base had 12 pieces of spinous bone plates and both sides of anal fin base had 8 pieces. One backward spines passed centrally through each bone plate. Six pieces of spinous bone plates passed through the abdomen and went left and right from the third. Seven pieces of spinous bone plates passed through the belly and went left and right from the second. Spines of the bone plate was small and formed ora serrata in belly and abdomen. Dorsal fin was 1 and one deep notche lied between spine and pterygiophore. The fin membrance extends into filaments between every two spines and the longest slender fin spine extends beyond the end of the tail fin. Based on the morphological characteristics and measurements, this fish was identified as mirror dory Zenopsis nebulosa, which was first recorded in this area. |
