Which is the biggest seed?

                  The biggest seed is the coco de mer, a kind of coconut that grows in the Seychelles, a group of islands in the Indian Ocean. The coco de mer seeds weigh 20 kg each, so it can be dangerous to walk beneath the parent tree. These giant seeds take 10 years to develop on the tree.

                   Strangely, the coco de mer does not grow close to the beach, so how the giant seeds reach the sea is still not understood.
