Blades originate from elongated stem-like structures, called the ‘Stipes’.
The holdfast, a root-like structure, anchors the kelp to the substrate of the ocean.
Gas-filled bladders (pneumatocysts) form at the base of blades to hold the kelp blades close to the surface.
A very clever act of nature on many levels.
If you dive in the waters of the Chatham islands for abalone, cod or crayfish, the thallus is a great hiding place from great white sharks.
This family decided to build their home on the Chatham Islands far from the thallus, but close to the stipes.
