This is the first time i see a yellow common shore crab (Carcinus maenas). Look at this tiny boy. #marinebiology #plyMBIO

This big boy is called Black Rock Crab (Xantho hydrophilus) and he just LOVES rock pools in the UK. He’s very shy and likes to hide under huge rocks, he’s also a very strong gripper and knows how to survive tide changes. A true survivor. #marinebiology #plyMBIO
