Under H2O

The Intertidal

5:49

One of the most difficult habitats for any organism to inhabit is the intertidal. Wave energy, temperature fluctuations, and salinity changes make living here impossible for all but a few of the hardiest plants and animals. In the 4th episode of our series UnderH2O, we sneak into this mostly unexplored habitat during the short window of time when the tide is out and the tidepools are accessible.
