"Nature" Names Tsukisome Anemone Research as One of November’s Best Science Images
Kumamoto University Research Breakthrough Captures Global AttentionA groundbreaking video from Kumamoto University's Center for Water Cycle, Marine Evironment and Disaster Management (Aitsu Marine Station) has been selected as one of "November's Best Science Images" by the scientific journal Nature. This special feature celebrates the most visually striking and scientifically innovative research images each month, and the selection is an incredible honor for Associate Professor. Yoshikawa and his team.
Associate Professor. Yoshikawa's research on the newly discovered Pink Sea Anemone—a species inhabiting the shells of hermit crabs in the deep sea—has earned international recognition. The image, which was featured in Nature’s November edition, showcases the remarkable metabolic ability of this anemone to build structures on the hermit crabs' shells, essentially creating its "home" in a unique symbiotic relationship.
The newly identified anemone species, Paracalliactis tsukisome sp. nov. is found exclusively on the shells of hermit crab Oncopagurus monstrosus, marking an extraordinary case of deep-sea mutualism. It is believed that the species' fascinating relationship with these crabs could reveal deeper insights into marine ecosystems and the adaptive behaviors of both organisms.
"Nature's Best Science Images" is more than just a collection of visually impressive research; it selects images that represent both scientific originality and visual impact. Associate Professor. Yoshikawa's research was honored not only for its groundbreaking academic contribution but also for the stunning imagery that vividly conveys the complex biological interactions at play.
The selected video, presented alongside the study's findings, beautifully captures the anemone's interactions with the hermit crabs in their natural habitat, making the study both scientifically significant and visually captivating.
Associate Professor. Yoshikawa commented on the achievement:
"I am deeply honored that our research has been recognized by Nature as one of the best science images. This accomplishment is a result of the collaborative effort of my dedicated research team, and I would like to thank everyone involved. My hope is that someday, the anemone will be displayed in aquariums and museums around the world for people to learn about this extraordinary creature."
The research, along with the captivating imagery, can be viewed on Nature's official website:
