Seaweed is adapted to live in rock pools through features such as the ability to tolerate changing water levels, temperature fluctuations, and high salinity. They have the ability to anchor onto rocks to prevent being washed away during high tides and can store water to survive during low tides. Seaweed species that inhabit rock pools have developed strategies to efficiently absorb nutrients and sunlight in these dynamic environments.

Rock pool predators have adaptations such as strong grasping limbs or claws to catch their prey in the turbulent water, camouflage to blend into the rocky surroundings and ambush unsuspecting prey, and a keen sense of smell or vision to detect prey in the murky environment. Additionally, some predators may have specialized mouthparts or teeth for crushing shells or tearing apart prey.
