sand dollar (Astriclypeus mannii)
Refers to a specific species of sand dollar. In everyday Japanese, the katakana name is used.
I found a sand dollar shell on the beach.
Katakana spelling is standard for this organism name; usually written in kana.
Rarely used kanji form; the kanji are ateji and not practical for learners.
The name スカシカシパン is a Japanese compound. The exact derivation is uncertain, but it is thought to combine 透かし (sukashi, 'openwork' or 'pierced') and 菓子パン (kashi pan, 'sweet bread'), possibly from the appearance of the sand dollar's test.
