Chocolate-Band Snail

Fascinating facts about the Chocolate-Band Snail

• Snail survived a London wall in 2006, showing how far this Mediterranean native can travel. One individual of this snail species was found living on a wall in Lewisham, London, England, in 2006. Even farther north, it can overwinter in temperate zones such as Belgium and the Netherlands, proving its hardiness beyond its sunny origins.
• Each snail can lay around 70 eggs, flooding its environment with potential new generations each autumn. Around 70 eggs per snail are laid 20 days later. The size of the egg is 4.1 × 3 mm. Yet only about 20% of the snails survive to lay eggs in the third year and just 5% manage a fourth reproductive bout.
• They grow over a centimeter each year, reaching breeding size after two years. Juveniles hatch shortly after and grow about 12-13 mm in diameter per year for 2 years. Maturity is reached after 2 years when the diameter reaches 25 mm, the umbilicus becomes closed and the apertural margin becomes reflected. but mortality spikes after the second year, limiting long-term survival.
• It's flagged as a top quarantine threat. This species has been introduced to southeastern Australia, where it is known as the chocolate-band snail. Eobania vermiculata has non-indigenous populations in Belgium, Germany, Hungary, the Netherlands, the US, Australia, Japan, South Africa, Egypt, Israel, Saudi Arabia, Jordan, and Iran. It is already established in the US, and is considered to represent a potentially serious threat as a pest, an invasive species which could negatively affect agriculture, natural ecosystems, human health or commerce. Hence, authorities recommend giving it top national quarantine significance.
• Its shell can reach a whopping 33 mm. The width of the shell is 22-32 mm; the height of the shell is 14-24 mm. In northern Greece, adults can grow to a maximum diameter of 33 mm, a size that may require five years or more to achieve.
