Biology

Physiology

File:Ishizumai no rock.png

An Ishizumai without a rock

Ishizumai resemble orange hermit crabs, with large pincers and dark, oval-shaped eyes supported by eye stalks. Its shell, however, is comprised of a sectioned chunk of gray rock. It has a hook-like tail that is concealed underneath the rock, possibly used to keep the rock in place.

Gender differences

None.

Special abilities

It has a special liquid that can dissolve a rock no matter how hard it may be. It is shown that Ishizumai firstly inspect a rock to see if it could become a good home, it then starts to dig a hole, and chip off pieces, it also uses a special liquid to dissolve the rock. When done it uses its hook-like tail to grapple onto it.

Behavior

If the rock where it lives breaks, it won't calm down until it can find another rock to replace it.

Habitat

It lives in the rocks where it bore a hole.

Trivia

• Ishizumai shares some similarities with Shuckle; they are both Bug/Rock, have Sturdy as an ability, and can dissolve rocks which they use for their home or protection.
• No other Pokémon has the same egg group combination as Ishizumai and its evolution.
• Despite being based on a crab, it cannot learn the move Crabhammer.

Origin

Ishizumai is based on a hermit crab, with a shell composed of rock rather than an exoskeleton.

Name origin

Ishizumai may be a combination of 石 ishi (stone) and 住まい sumai (dwelling, house), referring to its habitat.
