because with the starting snail population there was a great variation from 1-7. After the crab began eating only the snails with the thickest shells survived. The snails with the thinnest shells were eaten by the crab. Only snails with shell thickness 4-7 were left after the crab had their meal. The original snails with thickness 1-3 were eliminated from the population by the crab. The crab will usually try to expend as little enrgy as it can to maximaize its happiness so the snails with thinner shells

years ago‚ before the cell phone was invented and the values of that book apply to snails! Snails breakdown decaying plants for nutrients‚ then microorganisms consume that waste and effect the soil’s health which effects plants which help consume carbon dioxide. Midwest Pleistocene Vertigo can easily be saved‚ by less human contact‚ grazing should be decreased because decaying leaves is their habitat and food. Snails maybe 2.1 millimeters‚ yet the result of higher populations will be less carbon dioxide

famous snail in the field of learning and memory who was experimented on to understand how learning worked. The experiment started with shocking the Aplysia snail to teach it of the dangers of its new environment. When the snail’s siphon is touched‚ it triggers a defensive mechanism‚ a withdrawal reflex. It is this reflex that lets scientists know the Aplysia has formed new memories as it is on high alert and fearful from its past experiences of getting shocked. The scientists compared two snails‚ one

The study is focused on the evolution of the Littorina obtusata‚ also commonly known as the Flat Periwinkle Snail. This experiment focuses on Littorina Obtusata snails due to their evolution in shell thickness and shell shape. The purpose of the experiment is to understand the process of evolution and natural selection on organisms and why they occur; understanding the importance. By doing the experiment I hope to explore the effects of predation on a population‚ how predation influences evolution

limitation that affects the population of an ecological community is the dependency of hermit crabs on snail shell availability. Hermit crab species require snail shells to survive in their environment (Tricarico 2006). Shells are essential to habitat structure and processes (Gutierrez 2003). Hermit crabs are soft bodied crustaceans that cannot produce a hard exoskeleton themselves. The snail shells provide shelter from
