Hirondellea gigas is a type of gammaridea that inhabits the deepest waters of the world, including the Mariana Trench Challenger Deep, which is deeper than 7,000 m. It can be captured not only from the Mariana Trench but also from the depths of the Japan Trench and the Izu-Ogasawara Trench. Hirondellea gigas is a valuable deep-sea creature that can be caught by feeding traps. It is also a rare deep-sea creature that can ascend to the sea while retaining its shape. In addition to the white-spotted snailfish, the white-spotted snailfish also inhabit the water depth of 7,000 m, and gather in the bait trap. However, when the Shinkai Kusauo is pulled up from this water depth of 7,000 m, it becomes almost melted due to the decrease in water pressure. It may be said that Hirondellea gigas is the only deep-sea creature that can be observed in good condition.

Resin-embedded specimens of Hirondellea gigas were exhibited at the Deep Sea Exhibition held at the National Museum of Nature and Science.


The resin-embedded specimen of Hirondellea gigas, which will be rented out this time, is an individual captured in the deep trench of the sea near Japan. On the other hand, the Hirondellea gigas exhibited at the Deep Sea Exhibition was captured at the Mariana Trench Challenger Deep. Previously, as a result of comparing the trench near Japan and the Hirondellea gigas in the Mariana Trench Challenger Deep, it was reported that the results were morphologically and genetically identical. Previously, when I exhibited Hirondellea gigas at the Deep Sea Exhibition, it was put in a glass case. Also, it was exhibited a little away from the exhibition course. At the deep sea exhibition, it was not possible to observe the small Hirondellea gigas in detail. You can actually pick up the rented Hirondellea gigas resin-embedded specimen and carefully observe it from the top to the bottom, from the side, from the front to the back. Please try to join the ecology of deep-sea creatures.


The rental fee is 1000 yen per day + 1000 yen for shipping (excluding consumption tax) in Japan.


This time, the rental fee for the resin-embedded specimens of Hirondellea gigas is 1000 yen per piece! It costs a lot of money to catch Hirondellea gigas. However, we set it at a low price because we want many people to use it. I've heard that the annual budget of an elementary school science club is around 5,000 yen. The price is set so that it can be used for elementary school club activities.


Please use it for commercial activities and creative activities.


Previously, resin-embedded specimens of Hirondellea gigas were also rented by the Japan Agency for Marine-Earth Science and Technology. Actually, all the specimens were made by me, but I think the resin turned brown and was discarded. Even if it is on display, I don't think it looks good if it is browned. In addition, the Japan Agency for Marine-Earth Science and Technology lent it to educational institutions such as schools, but did not rent it for personal or commercial purposes. This rental can be used for personal creative activities and event exhibitions. Currently, deep-sea creatures are gaining popularity. It may be fun to show your child the real thing. In addition, it can be used for events to attract customers. When used at an event, we will also produce posters for explaining deep-sea creatures and Hirondellea gigas. With about 10 specimens of Hirondellea gigas and posters on display, you can expect a great effect of attracting customers. For posters, please contact us by e-mail regarding the content and target age.
