Why are rockpools the harshest places to live?

But nothing could be further from the truth, because a rockpool is one of our harshest habitats. Life here has to cope with a wide variation in temperature, oxygen levels and salinity, not to mention the turbulent tides that pound rocks and carry in fresh cargoes of predators.

Where are the anemones found in a Rockpool?

The anemones are found lower down in rockpools that never dry out, as they must stay underwater at all times. However, the anemones want to be as close to the surface as they can without drying out because they have a symbiotic relationship with photosynthetic algae, similar to corals, which need sunlight to flourish.

Where do sea scorpions hide in rockpools?

Like the sea scorpion, it is able to change the colour of its skin to blend in with its habitat. Shanny can be found hiding in rockpools, out of the water, under wet stones and seaweed, or in crevices. They are most mobile at high tide, when they will be found foraging over the shoreline.
