Title: Helix (gastropod)
Content: are due to predators and parasites. Since its publication in March 1974 issue of "Natural History" an estimate for the highest speed of garden snail equal to 0.03 mph (1.3 cm/s) became popular. However, the accuracy of this estimate has been questioned by Robert Cameron, who pointed out, that in competitions between snails only 2.4 mm/s speed had been achieved. There is a need for clarification and behavioural observation here though: competitions are usually held on the flat, whereas a snail's natural preference is vertical ascent, possibly an instinct derived from hatching in an earth 'pod' and having to climb

Title: Utah roundmouth snail
Content: to 5.5 m (up to 18.37 feet) and temperature up to 17.2 °C (up to 63 °F), and Utah valvata snail density was positively correlated with macrophyte (a water plant large enough to be observed with the unaided eye) coverage, water depth, and temperature. Similarly, Hinson (2006) analyzed available data from several studies conducted by the USBR (2001-2004), Idaho Power Company (IPC) (1995-2002), IDFG, Idaho Transportation Department (2003-2004) and others, and demonstrated a positive relationship between Utah valvata snail presence and macrophytes, depth, and fine substrates. One study reported Utah valvata snails in organically enriched fine sediments with a heavy

Title: Red-rimmed melania
Content: has been recorded in waters with a salinity of 32.5 ppt (1,024 specific gravity salinity). It is however a warm-climate species. It appears to prefer a temperature range of 18 to 25 °C or of 18 to 32 °C. Research has been conducted to determine the snail's lethal high water temperature, which is about 50 °C (120 degrees Fahrenheit). This information is helpful in the disinfection of fishing gear and research equipment, which otherwise may inadvertently spread the snails to uninfested waters. This species is resistant to low oxygen levels. The pollution tolerance value is 3 (on scale 0–10; 0

Title: White-lipped snail
Content: tolerates wetter and colder areas than the grove snail can. This species of snail creates and uses love darts during mating. The size of the egg is 2 mm. White-lipped snail The white-lipped snail or garden banded snail, scientific name "Cepaea hortensis", is a medium-sized species of air-breathing land snail, a terrestrial pulmonate gastropod mollusc in the family Helicidae. It is a close relative of the Grove Snail. The white-lipped snail is very slightly smaller than the grove snail, the shell being usually about in maximum dimension. Like the grove snail (brown-lipped snail), it has considerable variability in shell colour

Title: Land snail
Content: consist of up to 100 eggs. Garden snails bury their eggs in shallow topsoil primarily while the weather is warm and damp, usually 5 to 10 cm down, digging with their foot. Egg sizes differ between species, from a 3 mm diameter in the grove snail to a 6 mm diameter in the Giant African Land Snail. After 2 to 4 weeks of favorable weather, these eggs hatch and the young emerge. Snails may lay eggs as often as once a month. There have been hybridizations of snail species; although these do not occur commonly in the wild, in captivity

Question: What is the maximum speed of a garden snail: 0.03 mph, 0.3 mph, or 3 mph?
Answer: 0.03 mph
