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
