If you look on or between the leaves of Bell-ware, you will find creatures cleverly hiding. Horned shrimp and squat lobsters are green, just like the leaves, and hide on the undersides of the leaves with their long, slender bodies. The octopus, a member of the syngnathus family, wraps its flexible tail around Bell-ware leaves to support its long, slender body. It swims just like a torn leaf. Try looking for them in the "Small Creatures of Bell-ware Bed" aquarium.

Many small bubbles come out of Bell-ware leaves. What are they? They are oxygen bubbles emitted by Bell-ware. Bell-ware absorbs carbon dioxide through photosynthesis, creates nutrients, and releases oxygen. This function helps to prevent the rise in carbon dioxide concentrations and curb global warming, so the importance of Bell-ware beds is attracting attention.

Tokyo Bay once had vast tidal flats and many Bell-ware beds, but most of these have been lost due to landfilling and deterioration of water quality. Bell-ware beds are an important ecosystem that not only nurtures a diverse range of living organisms, but also purifies the water and functions as blue carbon, absorbing carbon dioxide through photosynthesis. Efforts are underway in various places to restore lost Bell-ware beds.
