High intertidal zone
Q. Do hermit crabs live in rock pools?
The crustaceans you are most likely to come across in a rock pool are the shore crab, hermit crab and common prawn. The shore crab does not easily dry out so it can live under stones and in cracks well up the shore, as well as in pools.

Q. How have hermit crabs adapted to their environment?
A marine crab’s adaptations include: their hard exoskeleton, their claws, and their concealing coloration—when an animal hides itself against a background of the same color. The Northern Hermit Crab has a soft and long, spirally curved abdomen.
Q. How do hermit crabs protect themselves from crashing waves?
3. How do they protect themselves from crashing waves? Their shells allow them protection from crashing waves. They can wedge themselves tightly into crevices in rocks and retreat into their shells to avoid being harmed or pulled out to sea.
Q. How do blennies protect themselves from crashing waves?
Blennies are tiny sea animals with long bodies that live in shallow water along the sea-shore. If the waves coming in from the sea are very strong, they can hide underneath rocks to protect themselves. Blennies have teeth that grow in their lips and these help them to scrape algae from rocks so they can eat it.
Q. What organisms have to adapt to low tides?
Barnacles, mussels, and kelps can survive in this environment by anchoring themselves to the rocks. Barnacles and mussels can also hold seawater in their closed shells to keep from drying out during low tide. Intertidal zones richer in sediments are filled with different species of clams, sand dollars, and worms.
Q. What do hermit crabs do at high tide?
Hermit crabs live near the ocean in tidal zones that are underwater at high tide, but out of the water during low tide. Their primary defense mechanism when scared or attacked is to retreat into their shell, hence the name.
Q. What is the life cycle of a hermit crab?
Hermit Crab Life Cycle. Hermit crabs can live 40+ years. They begin their life in the ocean then adapt to live the rest of their life on land. Mating between hermit crabs occurs when a spermatophore is transferred by a male to the female as both crabs partially emerge from their shells.
Q. What is needed for a hermit crab habitat?
Line the bottom of the terrarium with 2 to 3 inches of silica play sand, soil and/or coconut fiber; your hermit crabs will burrow into it when they’re molting. Create several hiding places in the terrarium. Furnish the habitat with at least 3-5 larger empty seashells per crab, to use as future housing.
