General Description
The
Helix Aspersa Muller, also referred to as the common garden snail, is one of
the most well known snail species in the world. As all land snails, the Helix
Aspersa belongs to the gastropod mollusk category. The Helix Aspersa snail is
one of the most populated land mollusks in the world.
Although
the Helix Aspersa snail is commonly known as the European Brown Garden Snail,
they have been given various scientific names. Some scientists have named the
species Cornu Aspersum, other refer to it as Cantareus Aspersus while others
have named it Cryptomphalus Asperses.
The
Helix Aspersa originally originates from Europe. Nonetheless, it has been
introduced in other countries throughout the world where they are regarded as
pests, destroying farmer’s crops and gardens.
The Anatomy of the Helix Aspersa Muller
Helix
Aspersa snails have one lung from which it breathes air. Their soft body is a
brownish colour, which is covered with slickly and slimy mucus substance.
Their
shells have a yellowy or creamy colour with brown-coloured circled rings. When
the snail matures its shell creates a lip on the edge which is attached on its
body. Their shell’s height usually ranges from 1-1.4 inches and its width
ranges from 1-1.5 inches.
The
Helix Aspersa snail’s foot is made up of a flat muscular organ that aids it
move. The snail moves by gliding on the ground. It exudes mucus to help it move
more smoothly by reducing the friction when moving on rough surfaces. The mucus
is the main reason snails leave a wet pattern of slime.
Generally,
the Helix Aspersa snail is active at night and very early in the mornings
before the sun is up completely. They are also active on rainy and cloudy days
when the sun is not bright and shinning.
Several
Helix Aspersa snails are known to hibernate during the winter season. Hibernation
is most common amongst mature snails. During spring they emerge from
hibernation and become active once again.
They
move extremely slowly. Their fastest speed has been recorded at 1.3 centimetres
every second.
The
Helix Aspersa snail originally originated from the British islands, Western
European countries and the Mediterranean. Through the passage of time they
reached other countries also like the Middle East and North Africa.
Today
they have been expanded in other countries like the USA, New Zealand, Mexico,
South Africa, Canada, Australia, Chile, Argentina to name a few. They are
regarded as nuisance and pests as they destroy agricultural crops and plants.
It is estimated that the snails were introduced into the new countries
accidently when plants or vegetable imports reached these countries.
The
Helix Aspersa garden snails are herbivores which feed on plants, crops, fruit
and cereals. Their mouths are found under their tentacles. Their mouth is dotted
with a toothed line known as the radula. The radula is rough enabling the
snails to tear their food. The majority of molluscs have a radula.
Similar
to other gastropod molluscs, the Helix Aspersa snails are hermaphrodites
meaning their body have both male and female sexual organs. Although
hermaphrodites can fertilise themselves, the Helix Aspersa snail needs to mate
in order to fertilise.
The
mating procedure of the snail is a complicated and interesting process. After
courtship, the mating process lasts from four to twelve hours. While mating,
the snails exchange a love dart which is a type of calcareous arrow. The
purpose of the love dart has not been explained yet.
Approximately
three to eight days after the mating takes place, both the snails deliver
approximately eighty to one hundred eggs. Each snail then creates a nest in
order to lay its eggs. They create the nest by digging the soil with their foot
approximately 1-1.5 inches deep. Each snail can carry and deliver eggs up to
six times every year. Each baby snail takes one to two years to fully mature
and develop into an adult snail.
Predators of Helix Aspersa Snails
Lizards,
frogs, worms, predatory insects and other snail species are common predators
that feed on the Helix Aspersa snail. Several bird species like the duck is
also one of the snail’s predators.
Humans eat the Helix Aspersa snail.
Most usually confuse this breed with the popular Helix Pomatia breed of snail
which is known as the Escargot.
Although the Helix Aspersa Snail is a
dangerous pest that destroys farmer’s crops and plants, its popularity is
constantly increasing in the cosmetic world sue to their mucus. The snail’s
mucus consists of regenerative features that are used in cosmetics in our days.
