The unique location of Heriot Bay makes it possible to explore a rich tidal zone when staying at the historic Heriot Bay Inn on Quadra Island.
Regardless of your level of experience Heriot Bay is a fascinating spot, you may be a seasoned marine biologist, an amateur naturalist, or just someone who loves nature, the intertidal zone of area is a captivating place to take a walk along the beaches of Quadra Island.
An intertidal zone is the shore area between the high tide and low tide marks. It is submerged and exposed due to the tidal cycles, creating a habitat that supports a variety of life that live in these conditions. The intertidal zone in Heriot Bay is particularly rich due to its rocky shores and sheltered bays, which provide various microhabitats. To fully appreciate an intertidal zone, it is best to visit during low tide. Wear sturdy, non-slip shoes to navigate the rocky terrain safely. Be mindful of the delicate ecosystems and avoid disturbing the organisms as you explore. A magnifying glass can be a handy tool to get a closer look at the intricate details of the smaller species.
A few creatures you might spot along the shores!
Star Fish!
The purple sea star is a common species in this area. They are easily recognizable by their star-shaped bodies and can often be found clinging to rocks in the tidal pools. Young purple starfish spend around six months feeding off plankton until they are large enough to begin hunting shellfish closer to shore.
Crustaceans
Crabs, and barnacles are also found in the intertidal zone. The shore crab, with its greenish-brown color, is a common sight scuttling across the rocks. These crabs are omnivores, feeding on algae and small invertebrates. Barnacles, on the other hand, attach themselves permanently to surfaces like rocks and boat hulls or the backs of humpback whales. They feed by extending their feathery appendages to filter plankton from the water.
Anemones
Resembling underwater flowers, sea anemones are another fascinating group of creatures you can find in the Heriot Bay marinas, anemones use their tentacles to capture prey. These animals have a symbiotic relationship with certain algae, which live within their tissues and provide them with nutrients through photosynthesis.
