For a better understanding of marine biodiversity

About BISMaL

BISMaL is a data system for biodiversity information, particularly in biogeographic data of marine organisms, constructed by Japan Agency for Marine Earth-Science and Technology (JAMSTEC), and is operated at the Global Oceanographic Data Center (GODAC) of JAMSTEC.

About BISMaL data

BISMaL provides biological information including photographs, descriptions on morphology/ecology, biogeography, etc. of marine organisms mainly around Japan. Movies taken by manned/unmanned submersibles of JAMSTEC may be found for some deep-sea taxa.

How to use BISMaL

Marine organisms registered to BISMaL are searchable by multiple methods. Scientific names, depth, localities or a combination of them, or search by browsing a taxonomic tree may lead you to each taxon page including detailed information of the taxon.

Information on background map.
BISMaL had used Google Map as a background map to display biological occurrence records. On October 5, 2018, we stated to use Natural Earth (Made with Natural Earth. Free vector and raster map data @ as a new background map.
Concurrently, we closed BISMaL Mapper service. Thank you for using BISMaL Mapper for a long time.

BISMaL Mapper

The BISMaL Mapper for Marine Species Distribution, in short, BISMaL Mapper, enables to create a distribution map of marine species or figure representing the spatial variation of marine biodiversity easily and quickly. You may also draw graphs based on the occurrence records of marine organisms on this tool. By default, the data retrieved from BISMaL is provided for the visualization on this tool. Additionally, you may register and login to the system to upload and visualize data downloaded from the Ocean Biogeographic Information System (OBIS) or Global Biodiversity Information Facility, or that compiled by yourself.
