The shore crab body is square shaped. Their abdomen is small and tucked under their body. The crabs’ exoskeleton is very hard, to protect them from their many predators. Their front legs have pincers that are used for hunting, feeding, cleaning, mating and protection. They use their other eight legs for walking.
They are often found hiding under rocks and in crevices of rockpools and rocky platforms. Where there are no rocks they will dig burrows. There are many different species of shore crabs. Some are good hunters. They help to keep the sea clean by finding and quickly eating rotting dead animals. They are important food items for octopuses and birds that feed along the seashore.
