Cellana radians, common name the radiate limpet, is a species of true limpet, a marine gastropod mollusc in the family Nacellidae, which is one of the true limpet families.


The foot and the head are lightly colored whereas Cellana flava has darker colored soft tissues. The shell exhibits different morphological varieties, even in the same location. The shell can be grayish white on the outside with rather flat ribs that are somewhat darker. Its interior is iridescent and white, with gray muscle impressions. The apex is off-center and sometimes worn off.
