Even though rocky shores are subject to some of the same abiotic factors as sandy beaches, such as changes in temperature and salinity, the species diversity is much higher in the former than the latter. What other variables do you think contribute to this high species diversity in the rocky intertidal?

What will be an ideal response?


The most notable difference between the two habitats is the greater number of diverse microhabitats in the rocky environment. This means that there are more niches that can be exploited by animals living in the rocky intertidal, which results in a greater species diversity.
