The Excretion of a Living Creature―A Sign of Activity Beyond Space-time
The action of excretion is a natural process, common to all living things. Therefore we can say that excreta is a sign which shows the way of life of the owner. If we examine it, we can understand what a living creature is eating as well as it’s behavioural pattern and habitat. Hence, excreta is valuable “circumstantial evidence” when we try to examine the ecology of a living being. The excreta, discharged into the environment, does not disappear. It is used by other living creatures and the constituent substances circulate through ecological systems. Sometimes, we can find the fossil remains of excreta preserved in geologic stratum. In such a case, we can understand the ecology of a living creature which lived in ancient times by examining the remains. In other words, excreta gives us useful information beyond space-time.
In this lecture, I am going to introduce how we can investigate the lives of living creatures from the action of excretion and its excreta from the view point of marine biology and palaeontology.

- Assistant professor at the Atmosphere and Ocean Research Institute, the University of Tokyo (Doctor of Science) 1981 born 2009 Ph.D. degree at the Graduate School of Science, the University of Tokyo 2009 - 2012 JSPS Predoctoral Fellow at the University of Tokyo, JSPS Postdoctoral Fellow at Port and Airport Research Institute 2012 (June) Current Position Here is his message: My speciality is marine biology and palaeontology. In my field-work, I analyse the burrows and crawl marks of living creatures which live in the bottom of the sea, and I study their ecology. I love going on cruises and diving although I get seasick whenever I sail.
