Organic Snail and Slug Control Nothing is more frustrating than heading out into the garden and seeing your seedlings and plants chewed up by snails and slugs. With just one night’s of feasting, the slimy pests can devastate a newly planted vegetable garden. Fortunately, gardeners have organic options in control that aren’t toxic to the surrounding ecosystem. What Exactly is a Snail and Slug? Believe it or not, but snails and slugs belong in the mollusk family. The main difference between the two is the slug doesn’t have the spiral external shell that snails do. Both use their muscular foot to glide along and this muscle secretes a slimly substance. When this substance dries, it leaves the silvery trail you will notice on foliage. Both snails and slugs are hermaphrodites, meaning they have both female and male sexual parts. Snails lay approximately 80 white, roundish eggs at a time into…

Cone Snail For centuries, the shells of the cone snail have been used as currency within small communities. Their shells each have unique patterns to them, making it great for jewelry and art pieces. But don’t let their innocent looks fool you. The cone snail is one of the deadliest animals in the world, mainly found in the Indian and Pacific oceans, and the Caribbean and Red seas. These creatures, like bees, aren’t aggressive until you mess with them. Many scientists are inspired by this…

Evolution by natural selection and predator induced phenotypic plasticity are mechanisms that have been proposed to describe the effect of crab predation on snail shell thickness. Biologist Robin Seeley hypothesized that the periwinkle populations of New England evolved by natural selection as the European green crab was introduced to the area (Seeley, 1986). The three requirements for evolution by natural selection are that there is variation among a population, the variation is partly…

source of morbidity and mortality for developing countries in Africa, South America, the Caribbean, the Middle East, and Asia (LAPA***). In these endemic areas, there are no resources for access of fresh drinking water and adequate sanitation. Therefore, human feces are the main source for spreading of Schistosomiasis. The causative agent of Schistosomiasis is Schistosoma, which is caused by a parasitic worm or a eukaryotic fluke (Colley, 2014). The parasites that bring about schistosomiasis…

Slow as a Snail, But Fast as 1-2-3 “My son loves to crawl around with this toy!! It does fall over a little bit but that is completely fine because my baby loves to look at himself in the little mirror. Overall, this is a great toy and I would buy it as gifts for other babies” (“Fisher-Price”, 2016).

Snails has been around Earth longer than the beginning of man. According to Samford Singer, gastropods appeared about 600 million years ago [2]. Today, there are thousands different species of snails varying from marine, freshwater, and land. All these species plays a huge role in a diverse ecosystem. They provide important food source to many different predator such as birds, fish, rodents, etc. Perhaps the most common snail is the garden snail, Helix aspersa. The body of a snail consist of…

I remember, as a child, somebody asking me if I would like a book for my birthday, I replied, “I…

Sarah Kummer Mrs. Dooley AP Lang 21 October 2016 The Benefits of Mistakes In The Medusa and the Snail, Lewis Thomas argues that mistakes need to be made in order to motivate individuals and improve mankind. Trial and error also allows an individual to learn from their mistakes and achieve their true potential. Throughout human history, mistakes have led to new discoveries and inventions. Humans have gained knowledge that would have otherwise gone unnoticed if these mistakes had not occurred.…

Throughout history, many important innovations have positively transformed the human way of life for the better. Although, these new discoveries were not made overnight. More often that not, mistakes are made, but these mistakes have in many instances lead to success. Lewis Thomas, author of The Medusa and the Snail, argues that nothing will ever be accomplished if mistakes are not made in the process. Thomas’s views are valid based on the amount of inventions and discoveries created by making…
