Male sperm competition in the golden cuttlefish plays a large role in reproduction. After maturity, males perform a variety of visual displays to attract a potential mate. Females often mate with more than one male during each mating season and retain the sperm from the various mates use for later fertilization. This leads to competition between males as well as sperm competition to fertilize the eggs. Male cuttlefish use their arms to remove the packets of sperm from other males off the buccal membrane of the female they intend to mate with, in an effort to ensure their sperm will fertilize the egg rather than the other males' stored sperm. |

'''The Effects of Global Warming and Commercial Fishing''' |

'''Environmental Impacts and Efforts:''' |
|||
In recent decades, ''Acanthosepion esculentum'' has faced a decline in population due to commercial fishing by Chinese, Japanese, and South Korean seafood companies. Until the 1990s, ''Sepiella maindron'' was the most fished cuttlefish in the region, but was later surpassed by ''Acanthosepion esculentum'' in popularity. The golden cuttlefish is harvested for both the meat from its mantle and for the medicinal properties of its cuttlebone in Chinese medicine. Given that this species of cuttlefish dwells on the ocean floor, fishing techniques such as cage fishing and trawling, which further disrupt their habitat. |

Along with the impacts of commercial fishing, global warming has caused harmful changes in the migratory patterns and population health of ''Acanthosepion esculentum.'' Due to raised temperatures in the colder waters this species winters in, the golden cuttlefish’s journey to coastal breeding waters is becoming more and more premature in recent decades. Given that many of the individuals have yet to reach full maturity, there are now higher mortality rates and worsened environments for breeding among ''Acanthosepion esculentum'' populations. |

'''Restoration Efforts:''' |
|||
In response to the decline in the regional populations of ''Acanthosepion esculentum,'' provinces in Northern China have taken measures to help promote and boost population numbers. Annual releases of captively-grown golden cuttlefish have been started and the placement of artificially made structures for ''Acanthosepion esculentum''’s eggs to attach to have been placed on the sea floor of regions around China. |
