Marine Biology Lab
Machine-translated · View original
A lab based at a marine biological station that studies marine organisms from cells to taxonomy.

AboutAbout the lab
Exploring marine life, from cells to taxonomy
The lab studies marine organisms, based at the Sugashima Marine Biological Laboratory on Sugashima Island in Toba, Mie Prefecture.
At the station, research teams collaborate and approach marine biology from many perspectives, from molecular biology and systematic taxonomy to oceanographic surveys.
The lab studies the diversity and evolution of marine invertebrates, and the cellular mechanisms of seaweeds and marine fungi.
The lab also has a Nagoya lab in the School of Science at Nagoya University (Chikusa Ward, Nagoya).
Key terms
- Marine invertebrates
- Marine animals without a backbone, including groups such as polychaete worms
- Molecular imaging
- A method of making the movements and functions of molecules inside living organisms visible for observation
- Environmental DNA method
- A method of identifying the organisms present in a place by analyzing DNA from organisms contained in samples such as seawater

At the Sugashima Marine Biological Laboratory, research teams collaborate and pursue marine biology from many perspectives, from molecular biology and systematic taxonomy to oceanographic surveys. The lab invites students to join it in research and fieldwork.
*Illustrative imageDiversity and Evolution of Marine Invertebrates
The lab compares the morphology and genes of marine invertebrates with those of known species, and describes any unknown species as new species, aiming to understand biodiversity. It also clarifies the evolution of form and ecology through observation of fine structures and observation of reared animals.
*Illustrative imageCells of Seaweeds and Marine Fungi
The lab studies seaweeds and marine fungi at the cellular level. For seaweeds, it aims to uncover their unique cell division mechanisms by observing the dynamics of the cytoskeleton and chromosomes and identifying the genes required. For marine fungi, it aims to understand cell dynamics and isolate novel bioactive substances.
*Illustrative imageDeveloping Analytical Techniques Tailored to Marine Organisms
Analyzing marine organisms with modern molecular biology methods requires techniques optimized for each organism. The lab currently focuses mainly on seaweeds, developing laboratory culture methods and techniques for molecular functional analysis and molecular imaging.
*Illustrative imageSurveying Seawater Temperature and Marine Life
The lab studies how the number of species and the timing of appearance of marine organisms change in response to environmental fluctuations. It measures seawater temperature and salinity in front of the station every day, and also monitors algae by diving and surveys fish using environmental DNA methods.
