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
This organ is involved in chemoreception - that is, in judging the nature of food or the substratum. In this sense, it can be considered a 'smell' or 'taste' organ; food is sensed before each stroke of the radula. [1] Nerve cells from the subradular organ join into the buccal nerves. [2]
The main cannabinoids in Radula marginata are not THC or CBD, the most common psychoactive chemicals produced by cannabis, but they are of similar molecular structure. [4] The liverwort contains perrottetinene and perrottetinenic acid. [4] It also contains a CBD analogue called Perrottetinene diol (trans-PTD) [6]. The proportion of cannabinoids ...
Raja radula distribution (in red). [6] Raja radula is a benthic species native to the Mediterranean Sea. [7] Some Atlantic records are probably misidentifications of Leucoraja naevus and/or Raja africana and need to be clarified. [8] This species inhabits coastal areas, between 2 and 300m depth on sandy or muddy bottoms of the continental shelf ...
Turritella radula is a species of sea snail, a marine gastropod mollusk in the family Turritellidae. [1] The Mollusk is found in the south-eastern Bioregion, it is found mainly in Santa Cruz. Mexico, Acapulco, Ecuador and the Galapagos islands.
Gahnia radula, commonly known as the thatch saw-sedge is a tufted perennial sedge native to south-eastern Australia. The leaves are long, flat and rough, with sharp edges. It has a distinctive brown inflorescence, which darkens to black. It grows to 50–100 cm in height, spreads through its rhizomes and is found in eucalypt forest and grassy ...
