octopus
Octopuses have soft bodies.
You can hide well by changing the shape of your body or the color of your body.
Clams
Clams belong to the same family as cockles (Hamaguri), which are all types of mussels.
They use their strong legs to burrow in forcefully.
Shiofuki and mategai are both members of the clam family, just like hamaguri.
I'll use my feet to dive into the bottom of the muddy, sandy sea.
crab
A crab relative, the Mokuzushoi, is walking around.
Because they have ulcers and other growths on their bodies, they are difficult to find if they stay still.
