You are an organism living along either a rocky or sandy beach. Tell me which organism you are, whether you're in the rocky shore or sandy beach, and identify the zone in which you live. Describe your typical day. Be sure to explain what you will be doing and why. How will you get food and avoid becoming food? Who are your predators? How will you survive the changing tides?

Crab in Rocky shore By rock pools - deep in ocean as they get older

Typical day - just shuffle along the rocks

To get food - from rock pools use claws to get fish

As they get bigger, they eat protozoa, diatoms and smaller crabs that live on the ocean floor. When the crabs reach 2 to 4 years of age, they move to deeper water where they join the adult crabs that eat worms, clams, mussels, snails and sea urchins. They also eat sand dollars, barnacles, fish parts and algae.

Hard shell is their protection and claws as a defends mechanism

PredAtors - possibly birds while on shore but bigger fish on ocean floor
