词源

From Late Latin radiolus (“a fossil echinoid’s spine”), from Latin radius (“rod, staff”) (possibly ultimately from Proto-Indo-European *reh₁t- (“beam, pole, post”)) + -olus (diminutive suffix) (ultimately from Proto-Indo-European *-lós). The word first appears in the works of Scottish natural historian and marine zoologist Charles Wyville Thomson (1830–1882).
