Metabolic responses to food and temperature in deep-sea isopods, Bathynomus doederleini

　A group led by Mitsuharu Yagi, Associate Professor at Nagasaki University's the Faculty of Fisheries, investigated changes in energy metabolism in response to feeding and temperature in the deep-sea isopods Bathynomus doederleini (Photo 1).

　The results showed that Bathynomus doederleini is a big eater, eating as much as 45% of its body weight in a single meal and increasing its metabolic rate after eating.
Based on this information, it was estimated that one meal could provide the energy necessary for survival for about six years when converted to whale blubber.
Information on how deep-sea isopods acquire and use energy is important for understanding the effects of climate change and diverse survival strategies.
The results of this research were published online in the international journal Deep Sea Research Part I: Oceanographic Research Papers on 3 March 2023.
