Sunlight Tree Eve

The Sunlight Tree Eve (陽樹イブ) is a colossal tree that absorbs sunlight and transfers it to its roots that also supply air to the ocean floor through respiration.

It is said by Neptune that it is like the boss of the Yurukiman Mangrove at the Sabaody Archipelago. It is through this tree's roots that Fishman Island is able to have light 10,000 meters below the surface of the ocean. It was first mentioned in Chapter 612.

Usopp notes there may be some connection between it and the Treasure Tree Adam.
