Sand Crab
The sand crab is a species of crab that lives in the sand and mud flats found all along the Pacific coast, from California to Alaska; they can also be found in Japan, China, Korea, and Taiwan. The life cycle of sand crabs begins when eggs develop inside their mother’s body; they hatch into larvae which live on their own until they are ready to grow up into adults. The larvae look like tiny shrimp with two large antennae (feelers). Their sandy translucent appearance makes them masters in disguise.
Sand crabs spend most of their time hidden beneath rocks or other debris on beaches, but at night, they come out onto open areas where there is less danger from predators such as birds or humans who might eat them. This behavior has earned them another common name: beach hoppers. They hop around on land instead of swimming through water like most crabs normally would during daytime hours instead of going back under cover before dawn breaks over again tomorrow morning.
