What life is in rock pools?

Rocks contain silicon dioxide and are a compound Above is true. But if the type of rock is igneous, sedimentary, or metamorphic then it can contain minerals, other rock fragments, and magma.


Why is it important to look after rock pools?

Rock pools are important ecosystems that provide a home for a variety of marine species. By looking after rock pools, we help preserve biodiversity and protect the delicate balance of these habitats. Additionally, rock pools are valuable resources for research and education, offering opportunities to learn about marine life and ecosystems.


How will sea levels rising affect rock pools?

Sea level rise can lead to higher water levels in rock pools, potentially changing the ecosystem by affecting the species that can inhabit them. This can lead to a loss of habitat and changes in biodiversity within the rock pools. Additionally, increased wave action due to rising sea levels may impact the stability and structure of rock pools.


How are rock pools formed?

As the tide recedes, not all of the coast is left behind dry. Depending on the type of rock, one can find shallow or deep rock pools. They offer better survival chances for animals and plants that need to be submerged all the time. Because each rock pool is different, they invite different communities. Deep rock pools near the low tide, have few survival problems, whereas shallow rock pools near the high tide, have many. Thus the pool's placing on the shore as well as its depth and size are important factors. Deep rock pools provide shelter from waves, allowing fragile organisms to live on an otherwise exposed rocky shore. Fragile animals are: sea slugs, shrimps, camouflage crabs, sea eggs, small fishes. Fragile sea weeds are: neptune's necklace, pillow weed, cystophora, sea lettuce and many others. For the snails that are able to survive in between high and low tide (periwinkle, nerita, melagraphia, cats eye) a rock pool is not necessarily a better place because their predators are found there (dark rock shell, white rock shell, trumpet shell). Large fish and octopus may find the rock pools too small, lacking oxygen for breathing. Rock pools may collect fresh water during rain storms, which is worse for shallow rock pools high up the shore where organisms must wait longer for the tide to return. Therefore, most rock pools are at the intertidal and backshore area.


Which rodents live in the porous volcanic rocks?

Rock hyraxes, also known as rock dassies, are small mammals that live in the nooks and crannies of porous volcanic rocks in Africa. They are herbivorous and have adapted well to living in such environments, utilizing the rocks for shelter and protection.
