Message from the IBO2020 Organizing Committee 

I am very proud to announce that we are holding the IBO2020 competition in Sasebo, Nagasaki. Nagasaki is a historical and memorable place, as it is the last place that experienced an atomic bomb attack. Nagasaki is surrounded by a beautiful sea with hundreds of islands, where you can enjoy numerous marine organisms. Immersed in nature, we are sure that all the delegates will spend a wonderful time with friends from all over the world. We warmly welcome you all with some new challenges including an international group work activity. In addition, of course, you will enjoy our scientific tasks. 

Looking forward to seeing you all in July 2020.

Narke japonica

Narke japonica

No.09 Japanese Sleeper Ray

Narke japonica is a species of sleeper ray belonging to the order Torpediniformes, whose members are known for their ability to produce electric shocks. This species can grow up to 40 cm in length, have a round pectoral fin, protruding eyes, and are reddish-brown in color. Narke japonica can be found in the ocean near southern Japan, Korea, China, and Taiwan. Slow-moving and benthic, this species feeds on invertebrates and is often found along sandy bottoms. Japanese sleeper rays are sometimes caught as bycatch of trawling operations and are listed as vulnerable by the IUCN.

Perkeomeris japonica

Perkeomeris japonica

No.26 Type of Millipede

Perkeomeris japonica is a species of pill millipede and a member of the order Glomerida. Growing up to 6 mm long, these millipedes are black with reddish brown stripes, have eleven or twelve body segments covered by hard plates called tergites, and have 17-19 pairs of legs depending on sex. Like others in its order, Perkeomeris japonica can roll up into a ball when threatened and produce an odorous liquid that wards off predators. Widespread throughout Japan, Perkeomeris japonica are detritivores. They can be found on forest floors or other dark, damp places where they can consume decaying vegetation.

Aspergillus japonicus

Aspergillus japonicus

No.12 Type of Fungi

Aspergillus japonicus is a species of fungus that belongs to the “black Aspergilli” section within the Aspergillus genus. Species in this section feed on decaying matter, are usually found in soil and organic debris, and includes the species that causes black mold, Aspergillus niger. Though some species of black Aspergilli have been implicated in causing disease and food spoilage, other species are used by the fermentation industry to produce hydrolytic enzymes and organic acids, like citric acid. Aspergillus japonicus can been used to produce a variety of enzymes, including invertase, which catalyzes the breakdown and digestion of sucrose.

Mauremys japonica

Mauremys japonica

No.06 Japanese Pond Turtle

Mauremys japonica is a species of freshwater turtle native to Japan. Females of this species can grow shells up to 21 cm long, while males grow smaller shells up to 14 cm long. Found across Japan except for the northern island of Hokkaido, Japanese pond turtles live in rivers, marshes, ponds, and irrigated rice fields. Its diet can include small amphibians, insects, algae, and earthworms. Although not currently considered threatened, habitat destruction via land development, exploitation from the pet trade, and the introduction of invasive turtle species have caused concern for native populations of Mauremys japonica.
