Just one example is the giant bull kelp Nereocystis luetkeana, which have evolved to change blade shape in order to increase drag in water and interception of light when exposed to certain environments. Bull kelp are not unique in this adaptation; many kelp species have evolved a genetic plasticity for blade shapes for different water flow ...

Red abalone live in rocky areas with kelp. They feed on the kelp species that grow in their home range, including giant kelp (Macrocystis pyrifera), feather boa kelp (Egregia menziesii), and bull kelp (Nereocystis luetkeana). Juveniles eat coralline algae, bacteria, and diatoms. [7]
A curious sea creature stalked a team of divers through a giant kelp forest in California, and even decided to nibble on one of their wetsuits.
