What is the function of love darts in Helix mating?
The love dart’s role during the mating process According to another hypothesis, the love dart is a gift of calcium to the receiving snail. That would at least help in the production of egg shells. Calcium carbonate, besides, is an important resource for snails, that must be taken in from nature.
Are snails reptiles or amphibians?
A common misconception is that snails are amphibians – although some snails are found on land and some in water, these are two distinct varieties; snails are not amphibians. There are four reptile orders in existence today. Crocodilia refer to animals like crocodiles and alligators.

What is radula function?
The radula, part of the odontophore, may be protruded, and it is used in drilling holes in prey or in rasping food particles from a surface. It is supported by a cartilage-like mass (the odontophore) and is covered with rows of many small teeth (denticles).
What are cilia and radula used for?
The radula is unique to the molluscs, and is found in every class of mollusc except the bivalves, which instead use cilia, waving filaments that bring minute organisms to the mouth. Within the gastropods, the radula is used in feeding by both herbivorous and carnivorous snails and slugs.
What is the chemical composition of a love dart?
calcium carbonate
Abstract. The love dart of the snail Helix pomatia is a four-bladed, hollow spicule of calcium carbonate. The calcium carbonate is largely in the form of microcrystalline aragonite, the crystals being not more than 0.5 μm in size but assembled into sheets or blocks of much greater size.
Which animals use a Gypsobelum or love dart?
A love dart (also known as a gypsobelum, shooting darts, or just as darts) is a sharp, calcareous or chitinous dart which some hermaphroditic land snails and slugs create. Love darts are both formed and stored internally in a dart sac.
