Molecular clock analyses indicated that Dactyloradula diverged from other Radula species during the Mesozoic era, positioning it as an ancient genus-level lineage. The estimated age of divergence placed it as old as many flowering plant families, unusual for what was previously considered just one species within a larger genus.
The radula (US: / ˈ r æ dʒ ʊ l ə /; pl.: radulae or radulas) [1] is an anatomical structure used by mollusks for feeding, sometimes compared to a tongue. [2] It is a minutely toothed, chitinous ribbon, which is typically used for scraping or cutting food before the food enters the esophagus .
The most common compounds found in Radula species are 3,5-dihydroxy-2-(3-methyl-2-butenyl)bibenzyl and 2-geranyl-3,5-dihydroxybibenzyl, which often form the basic structure for more complex molecules in these plants. [17] Of particular interest is the presence of compounds similar to those found in cannabis (cannabinoids) in some Radula species

Radula visianica is a small, green to yellowish-green plant that grows in patches. Individual shoots are typically 0.3–1.5 mm (0.012–0.059 in) wide and can reach up to 20 mm (0.79 in) in length.
