摘要

据报道，在莫桑比克南部伊尼扬巴内省的维兰库洛斯沿海野生动物保护区的受保护水域内，相隔两年分别发现了拟态章鱼Thaumoctopus mimicus Norman & Hochberg, 2005。个体分别于 2020 年 5 月和 2022 年 5 月在水深小于 30 厘米的浅水区被发现。两只个体都完全暴露在潮汐平地水边的沙质基底上。这是在莫桑比克首次发现模仿栉水母的记录，证实了该物种出现在非洲东海岸，并将该物种的已知分布范围从阿拉伯海向西扩展到红海以南。

First sightings of mimic octopus Thaumoctopus mimicus (Cephalopoda: Octopodidia) from the Southwest Indian Ocean with photographic records from the Inhambane Province of southern Mozambique

Two separate sightings, two years apart, of the mimic octopus Thaumoctopus mimicus Norman & Hochberg, 2005 are reported from the Inhambane Province of southern Mozambique within the protected waters of the Vilanculos Coastal Wildlife Sanctuary. Individuals were encountered in May 2020 and 2022 in shallow waters, at a depth of less than 30 cm. Both individuals were fully exposed moving along a sandy substrate at the water's edge in a tidal flat. These represent the first documented sightings of T. mimicus in Mozambique, confirming the occurrence of the species along the eastern coast of Africa and extending this species' known range west from the Arabian Sea and south from the Red Sea.
