What is an intertidal zone?
An intertidal zone is a marine ecosystem that lies between the high tide and low tide line along the coast.
Why are intertidal zones important?
When the tide retreats, it leaves behind shallow pools that stay trapped in the shore’s rocky gaps and cracks. Some of the pools are large enough for a dip, others are palm-sized, but each one pulses with life. They serve as nurseries for juvenile fish, habitats for several marine creatures and feeding grounds for shorebirds.
Which creatures can you spot in an intertidal zone?
You can spot several marine species such as mudskippers, sea slugs, sea anemone, shore crabs and more in the intertidal zone.
