Rocky Intertidal Zones and Species

The video explores the rocky intertidal zones in Monterey Bay, focusing on the splash, high, mid, and low zones. Each zone is described in terms of its unique characteristics, species, and ecological importance. The splash zone is mostly bare rock, the high zone features scouring pad alga, the mid zone is dominated by mussels, and the low zone includes surf grass and tide pools. The video emphasizes the importance of these zones for scientific study and ecosystem health monitoring.

What are the four zones of the rocky intertidal mentioned in the video?

• Splash zone, high zone, mid zone, low zone

• High zone, splash zone, deep zone, low zone

• High zone, mid zone, low zone, deep zone

• Splash zone, mid zone, low zone, deep zone

Which zone is characterized by mostly bare rock and is only reached by the highest tides?

• Mid zone

• Low zone

• Splash zone

• High zone

What is a common algal species found in the high zone?

• Coral line algae

• Iridescent algae

• Scouring pad alga

• Surf grass

What role do the splash zone areas play for birds?

• Nesting and resting areas

• Breeding sites

• Feeding grounds

• Migration stopovers

Which species is a prime indicator of the mid zone?

• Sunburst anemone

• Scouring pad alga

• California mussel

• Surf grass

What adaptation helps mid zone species like mussels survive the tidal cycle?

• Thick shells to prevent desiccation

• Ability to photosynthesize

• Ability to fly

• Bright colors to deter predators

Which species is commonly found in both the mid and low zones?

• Rock weeds

• Scouring pad alga

• Turban snails

• Giant green anemones

What is a unique feature of iridescent algae found in the low zone?

• It is bioluminescent

• It is rubber-like and snaps back when pulled

• It changes color with temperature

• It can survive in freshwater

Why are the rocky intertidal zones important for scientific study?

• They have a high diversity of species

• They are unaffected by climate change

• They provide defined areas to track ecosystem health

• They are easy to access

Which zone is always covered by water?

• High zone

• Tide pool or subtitle area

• Splash zone

• Mid zone
