Are rock pools microhabitats?
Rock pools are extremely productive microhabitats that contain a diverse range of plant, invertebrate and fish life; however, they are isolated and patchily distributed along the shore and are highly variable in time (i.e. tidal, seasonal and diurnal) and space (from geographic to local scales) (Martins et al.
Why does a rock pool have higher biodiversity?
Rock pool structural complexity plays a role in determining which species are found in them. A deeper rock pool can mean more space for different species, and a greater volume of water is less likely to have large fluctuations in salinity, temperature and oxygen levels, creating a more stable environment.
What sea creatures live in rock pools?
Seaweeds, corals, worms, sponges, barnacles, limpets and other molluscs like mussels, snails, whelks, nudibranchs and oysters may be found in the depths of rock pools.
What is the source of energy in the rock pool?
the sun
Almost all of the energy that supports the life in the pool arrives in the form of light from the sun. Some of this energy is captured by seaweeds attached to the rocks and microscopic plants (types of plankton). These plants are eaten by animals, which are eaten by other animals, and so on.
Who lives rock pool?
The only vertebrate animals you are likely to come across living in a rock pool are a few species of fish. Rock pool fish may be permanent residents or just visitors stranded by the tide. The fish you are most likely to come across from the upper shore downwards is the common blenny or shanny.
What is a rock pool ks1?
Description. Creatures living in a coastal rockpool must adapt to the water being heated by sunlight and diluted by rainwater, as well as to the water levels dropping. In a rockpool at the coast we are introduced to an anemone. Anemones are animals which are found all along the shoreline.
Why are rock pools important for the coast?
On rural coastlines, rock pools form naturally over centuries or millennia and serve as refugia for marine life, offering protection from the elements and predators, and consequently support a high diversity of species.
Does rock pool volume impact species diversity and abundance?
Species diversity increased with pool size (Table 1b). This effect was mostly correlated with depth and volume, but not with area. In early-successional pools there was a significant positive relationship between pool depth and species diversity at both locations on the lower, but not on the upper shore.
Can you find seahorses in rock pools?
Seahorses are related to the pipe fish, a long, bootlace-like fish that is quite common in rock pools. The seahorse can remain still for very long periods, secured by its prehensile (it means good for gripping hold of something) tail and well camouflaged among weeds, eelgrasses and corals.
