Characteristics
A small crab with a shell size of about 3 cm. It camouflages itself by wearing seaweed on its head. Body color varies from red to green. The shape of the shell differs between males and females, with females having a wider shell, while males have a triangular shape.
Ecology
It mimics the surrounding seaweed to live. During the day, it hides in seaweed and becomes active at night.
Habitat
Hayakawa beach at night
Taken during a night dive. It also had two pieces of seaweed on it. It looked quite conspicuous when I saw it in a place where there was no seaweed around.
