Tough as snails

The lowly sea snail, of all things, has a unique way of manufacturing armor from soft ingredients. God equipped one of the simplest and slowest of creatures with a surprisingly robust shell that combines two brittle ingredients. Scientist are only beginning to understand and replicate this new way to create “composite” materials that could lead to new and better products At first glance, the shell of the snail does not seem so impressive. The ear-shaped armor consists of mainly calcium carbonate, which is the same compound in Tums tablets, but when that compound is stacked in a special way it becomes quite durable. Recently researchers in Zurich Switzerland discovered ways to mimic the process that manufactures this “snail-strength”. Although God designed the snails shell to be used a more complex way, it inspired scientists to developed similar convenient ways to produce structures

    The shrimp also uses its club to break rock it will do this as a way of extending its burrow or cave. The speed of the strike (up to 50 mph, or 23 m/s) creates cavitation bubbles between the shrimp 's hammer-like club and the struck object. The bubbles collapse, and generate heat, light, and sound. Though the mantis shrimp 's tough club is impregnated with hard minerals it will still shed it and regenerate it every few months.…

    Did you know that the mantis shrimp is the boxer of the sea. With the use of a hyperbolic porabola on the underside of its elbow, the peacock mantis shrimp can puch as fast as a 22 caliber bullet. It's punch can also create a cavitation bubble on impact, something you usually see with explosions under water.…

    Known as Birgus latro it is a derived type of hermit crab. Only young crabs use snails shell to protect their soft abdomens, adolescents sometimes are seen using broken coconut shells to protect their abdomens, hence the name coconut crab. Unlike all other hermit crabs, the adult crabs do not carry a shell but instead harden their abdominal terga by depositing chitin and chalk. Not being constrained by the physical confines of living in a shell allows the species to grow much larger than other hermit crabs in the family Coenobitidae. Like most crabs, the coconut crab bends its tail underneath its body for protection. The hardened abdomen protects the crab and reduces water loss on land. These animals are true crabs that shed their exoskeleton annually. The adults dig a burrow up to 1m long to hide while they are vulnerable in the process of moulting (shedding). It remains in the burrow for three to sixteen weeks, depending on the size of the animal. After it is done it takes one to three weeks for the exoskeleton to…

    The phalanges of forelimbs limbs also became extended, thin, and flattened to gain optimum resistance to water while swimming (Le Buff 1990). This makes the limbs poorly adapted for terrestrial movement; however, because of the importance of aquatic movement in sea turtles, sea turtle species have adapted to have uncompromised adaptations for aquatic locomotion, while evolutionary sacrifices were made for terrestrial locomotion, making movement on land more slow and labored (Pritchard 1997). The loggerhead turtle has a relatively large head and beak compared to other turtles. Loggerhead turtles also have a harder and stronger mandible than other turtle species. This is because it is adapted for it’s foraging behavior of crushing hard bodied organisms such as mollusks. The neck of turtles of the Cheloniidae family is short. All turtle species in this family have lost the ability to completely retract the head and limbs. This is likely due to adaptation to marine existence. The skull of turtles of the Cheloniidae family also provides more protection compared to other turtles (Kamezaki…

    In the 1980’s the Asian shore crab arrived in the waters around New England, and it quickly became one of the most dominant crab species in New England (Science Daily, 2006). However, the blue mussel that is native to the are has evolved to defend itself against the dominant crab which eat the mussels by crushing their shells. The favorable adaptation of the crab is its ability to thicken its shell in when an Asian shore crab comes close to it.…

    In the video “Making Stuff Stronger,” David Pogue explores the various types of strength in a material and how scientists can change the amount of it. Scientists can strengthen either a material’s compressive strength, tensile strength, or toughness. In addition to that, they can also create entirely new materials for real world purposes by altering the chemical structure. One example of this is a synthetic polymer with very high tensile strength and toughness called Kevlar®. Soldiers wear it as part of their uniforms because it is a tough “shield” against bullets. However, Kevlar® is not the absolute strongest material. Other scientists have discovered how nature produces strong materials, such as a toucan's beak or spider silk. By studying the natural world, our world can now grow carbon nanotubes and make artificial spider silk by genetically engineering goats to produce milk that contains spider silk…

    Stomatopods, also known as mantis shrimp, are an ancient group of marine arthropods that belong to the class Stomatopoda. There are approximately 350 species of stomatopods that have been discovered to date, ranging in size from 1 to 30 cm. (Caldwell 1975) Stomatopods are a group of crustaceans that belong to the class Malacostraca, along with familiar crustaceans such as crabs, lobsters, and shrimp. The malacostracans are defined by their unique bauplan, which consists of a segmented body divided into three distinct tagmata: the head, thorax, and abdomen. All living stomatopods are represented by four families: Squillidae, Lysiosquillidae, Gonodactylidae, and Bathysquillidae. (Caldwell 1975)…

    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 / interferes with natural selection, the effects of the introduction of a non-native species on populations, and how evolution and natural selection is affected by non-native species. I expect to find that the snails’ shell thickness and shell shape…

    The class of Gastropod is closer to the hypothetical ancestral mollusk than the other classes of mollusks. Gastropods such as snails have a similar body layout that contains the basic broad foot, shell with mantle inside, and mouth with radula present. The class Bivalve, on the other hand, looks to be drastically different in appearance than the Gastropods. Bivalves such as clams have two distinct halves that open and close by muscles. Although they look entirely different they have many of the same physical characteristics. Clams also have a foot present although it is not as broad as that of a snail. Clams have a…

    You’ll need to apply at least two theses to Frankenstein using examples from two different volumes of the text. You’ll also need to apply at least one thesis to The Strange Case of Dr. Jekyll and Mr. Hyde. For the entire essay, the minimum number of theses to discuss is three (three different theses), but you are welcome to go beyond that number and include an additional thesis that apply to the novel or the excerpt. Keep in mind that you need to demonstrate your reading of the entire novel Frankenstein, so the examples need to come from different volumes.…

    This conclusion is based on the moon snail’s preference of preying on the small to moderate sized bivalves. Because smaller bivalves are more likely to be preyed upon both the incongruous and blood ark populations will evolve in favor of having a larger shell in order to better survive against their environmental factors. This conclusion is further supported by the type of selection seen within the incongruous and blood ark populations, which was directional. Because one extreme seemed to be favored in terms of survival the frequency of the bivalve population will most likely shift towards the larger sized…

    All monsters have that one thing that sets them apart from the rest whether it’s the notorious big foot and his big foot, Michael Myers and his huge kitchen knife, or even werewolves and the fact that they transform when a full moon is out. Every monster is unique and different, but in the book Monsters there are seven theses and one thesis stood out. Theses number six in the book Monsters states that “Fear of the monster is really a kind of desire.” That thesis is true when it comes to a certain fictional monster by the name of Freddy Krueger.…
