reproduction of snails catches the attention of some people because they usually are unique processes. snails have a striking appearance, but their reproductive habits are also uncommon.
the first thing you should know about these terrestrial gastropod mollusks is that most are hermaphrodites. hermaphrodite is called any organism that has male and female reproductive organs and therefore can produce both eggs and spermatozoa. it is like if the snails were male and female at the same time.
before the intercourse, both approach to start the courtship process consisting of a series of movements and attitudes that will finish or not in the mating. the entire process can last as little as 2 hours or as long as 12 hours. to find a partner, they primarily rely on their sense of smell and touch, as their visual capacity is poorly developed and devoid of hearing. they can recognize chemicals in the air that communicate the receptivity of some other snail nearby.
during the process, both land snails get closer, acknowledging each other and “testing the odds.” as they approach, they begin to interact in a more physical way and can touch each other with the help of their tentacles. some move in circles and can bite the area of the genital pore.
in the final stage of courtship and before mating, some species use a unique weapon: the “love darts.” no, it is not a metaphor, it is a structure of calcium or chitin that only sexually mature snails have, and usually that have mated more than once. seen in detail, they indeed resemble pointed darts.
when both are close enough and touch their genitals, they shoot their love darts. darts are not fired away but are a contact shot. usually, the two snails shoot the structures, and they pierce the skin of the other so that they are united. the dangerous thing about this is that sometimes darts can damage an internal organ or go through the body and exit on the other side.
the function of love darts is not transferring sperm but is a form of sexual selection, and observations concluded that garden snails (helix aspersa) could increase their reproductive success. the mucus that covers a dart contains a type of hormones capable of increasing the chances of success to have offspring.
after the snails shoot their “love darts,” copulation follows. the transfer of sperm through the ***** may be reciprocal or unilateral; this means that either both transfer
