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.

Scolopendra subspinipes japonica
No.35 Type of Centipide
Scolopendra subspinipes japonica is a species of venomous predatorial centipede found across Southeast Asia and East Asia. A large species, it grows to lengths of 75-130 mm. It has 21 dark green body segments, a reddish-green head, and one pair of dark yellow legs per body segment. In Japan, it can be found in forests, grasslands, and residential areas on the islands of Honshu, Shikoku, and Kyushu. While it stays hidden during the day under rocks, leaves, or in homes, at night it hunts spiders, cockroaches, and crickets. Its venom is poisonous to humans and can cause pain and swelling.
No.37 Type of Green Algae
Lychaete japonica is a species of marine green algae of the order Cladophorales. Whitish-green when alive, it grows in strong, upright, branched fronds that look dense and tufted. Most plants of this species grow up to 20 cm tall and are dark green when dead and dried. Found in the ocean south of the Tsugaru Strait in Japan, it grows on rocks near the low tide zone or in shallow water depths. Other Cladophorales species from the mid-Ordovician have possibly been found in the Winneshiek Shale in Iowa, USA.
Omphalotus japonicus is a species of mushroom known in Japan as “tsukiyotake” or “moon night mushroom.” Like others in its genus, Omphalotus japonicus has a bioluminescent body in darkness. In daylight, it is often brown or orange, with caps that grow in a kidney or half-circle shape. It can be found in beech trees in cool, temperate forests in Japan, China, eastern Russia, and Korea. Omphalotus japonicus is poisonous if ingested, causing nausea and vomiting. It is often mistaken for other mushroom species that are edible, such as Shiitake and Hiratake mushrooms.
No.24 Shijimi (Japanese Basket Clam)
Corbicula japonica is a species of mollusc that is popularly used in Japanese soup recipes. They belong to the class Bivalvia, whose members have soft, invertebrate bodies encased by two hinged calcium carbonate “valves,” or shells. Japanese Basket Clams have rounded triangular shells that grow up to 30 mm long and are black, brown, and yellow in color. They are widespread in brackish water near the coasts of Japan, Korea, eastern Russia, and China. Corbicula japonica can be found burrowed in the subtidal sands of lagoons, lakes, and estuaries that are connected to the sea.
