A scyphozoan jellyfish, Sanderia malayensis, was collected from the Ryukyu Archipelago, Okinawa. The umbrella of this species reaches 15 cm in diameter. Its tentacles and umbrella contain nematocysts. The Japanese name of this species is Amakusa kurage and is named after the Amakusa region where they are commonly found.
Sanderia malayensis is widely distributed in the subtropics and tropical regions of the Indo-Pacific. There were reports of its appearance in several parts of Japan, however there had been no reports of this species found in the Ryukyu Archipelago. This was the first discovery of Sanderia malayensis in the Ryukyu Archipelago, Okinawa.
