Branches of the live oak (Quercus virginiana) loop and twist their way toward openings in the forest canopy. Many branches sag down to the ground before stretching back up again.
These low branches help the oak survive in the hurricane-prone regions of the southeastern US. Short, wide trees resist strong winds better than tall, thin ones.
Those curvy branches helped the USS Constitution stay afloat during the War of 1812. Live oak limbs were frequently used in ship building due to their natural bends, strength and density.
