porcelain crab
A decapod crustacean of the family Porcellanidae. Not a true crab, but resembles one. The Japanese name literally means 'crab deceiver'.
I found a porcelain crab on the rocky shore.
Kanji form with okurigana; rarely used.
Compound of 蟹 (kani, 'crab') + 騙し (damashi, 'deceiving'), from the verb 騙す (damasu). The name reflects the fact that porcelain crabs resemble true crabs but belong to a different group.
