I did my Biology at University College,—getting out the ovary of the earthworm and the radula of the snail, and all that.
It is a mollusk because it has a mantle, a foot, and a radula.
This is called the radula, and is used for tearing or rasping the food.
Conus is accused of having a poison-gland connected with the radula and of having shown vicious traits when captured.
Head broad, surrounded by a funnel-shaped velum or hood; no radula; dorsal appendages foliaceous.
The Testacella also resembles the tiger and the shark in the possession of long, fang-like teeth upon its radula.
In front of the radula is the so-called tongue, a fleshy projection corresponding to the sub-radular organ of other Mollusca.
radula with very numerous marginal teeth arranged like the rays of a fan.
Teeth of radula beam-like, and at most three marginal teeth on each side.
The radula has a number of uniform teeth on each side of the median tooth in each transverse row.
