| 利用现场观察和数码摄像机记录的方法对虎斑乌贼(Sepia pharaonis)繁殖行为学进行研究。结果表明, 虎斑乌贼的繁殖行为谱包括游泳、休息、捕食、求偶、争斗、交配、产卵等行为, 虎斑乌贼早晚常离底游动觅食, 白天下沉水底, 捕食甲壳类和幼鱼等。在隐蔽阴暗处休息, 在交配行为上不是“一夫一妻”制, 存在一雌多雄交配现象, 交配前有较复杂求偶行为, 包括雄性争斗与对峙、雌性配偶的选择等, 交配为头对头的方式, 雌性受精不久便在产卵区轮流产卵, 卵呈白色, 半透明, 卵群葡萄状, 卵径约14-16mm, 长径约27-34mm。 |

| Abstract: |
| In this paper, the reproductive behaviors of cuttlefish Sepia pharaonis were studied with field observation and recording using Digital Video Recorder. The results show that their reproduction ethogram included in swimming, rest, predation, courtship, struggle, mating, and spawning. In the morning and night, cuttlefish of S. pharaonis often swam to find food from the bottom of sea and in the daytime, they sank to the bottom to prey on crustaceans and juvenile fish etc. in addition, they rested in the shadows of concealment. Their mating was a polyandry instead of monogamy. Before mating, they showed complicated courtship behavior, including struggle and confrontation against other males, and chosen females. The mating pattern was “head-to-head”. Before long, females spawn in the spawning area in turns. The eggs were white and translucence, and the eggs clustered in botryoidalis. Eggs diameter was 14-16mm, in length of 27-34mm. |
