The baobab stores thousands of gallons of water in its spongy wood.

The elephant has a special relationship with the baobab, eating its fruit and spreading its seeds. The elephant also uses this tree as a key water source during migration, using it's water-rich inner wood to quench their thirst on long migrations. This damages the baobab, but it normally regenerates. Global warming has disrupted this cycle.
