Exoskeleton

They clean our beaches and salt marshes, filter out small things in the ocean, and shed their old shell, just to eat it again. What kind of animal could this be? A Fiddler crab! They do all those things to help themselves. They don’t even know they are helping the entire world! Fiddler crabs live in many places. They live in mangroves, salt marshes, and on sandy and muddy beaches. Fiddler crabs are important to salt marshes because when they feed and burrow, they clean the salt marshes and…

known also as the largest carbon sink. (http://www.nrdc.org/oceans/acidification/dive-into-the-science.asp) One of our most vital ecosystems could be lost due to the continuous burning of coal. Most of our crabs, corals and other animals with exoskeletons are composed with calcium carbonate which helps give them that boney exterior structure that some even call home. It has even got so bad in some areas that snails and other animals that use calcium carbonate for their shell aren’t getting…

There are many biotic factors that are being impacted in the lake’s ecosystem. However, the most affected animals include the crayfish, clams, and mayfly. Crayfish need calcium in order to maintain a healthy exoskeleton. However, when a lake’s pH decreases, most of the minerals diminish as well. Affecting the crayfish in the process as they are weak and their source of food is being limited as well. Crayfish can be found in Australia and many other parts of the world but most commonly in North…

Just north of Key Biscayne in sunny Miami, Virgina Key is a protected barrier Island in the Atlantic ocean. Consisting of 863 acres of land, it was once much larger, extending into the Ft. Lauderdale area. Between 1835 and 1838 hurricanes eroded the beach, creating inlets and dividing the island in two. The other portion became Fisher Island, which sits at the southernmost tip of Miami Beach. Virgina Key was a part of the civil rights movement. In a time when blacks were prohibited from going…

Forensic Entomology Forensic Entomology is the study of insects and arthropods which help aid the legal system. This includes insects, arachnids, centipedes, millipedes, and crustaceans most commonly maggots are used. Forensic entomology can not only aid in murder investigations but it can also be used to detect abuse of children and the elderly, to determine the location of the crime scene if the body had been moved, termite damage or even bugs in food. History Forensic Entomology was first…

different and dangerous. Their appearance has the ability to make people feel unease and dread by just looking at them. For example, Count Orlok has fangs, big claws, pale skin, pointy ears, and nose. Xenomorph has a vertebrate-like body, a protective exoskeleton, a long-domed head, and an inner mouth that can stretch. For Pale Man, he looks like an old man with anorexia and his eyes is on his hand. Last but not least, those monster feels…

reduces the water’s ability to absorb and muffle low frequency sound by 40%, which makes certain parts of the ocean noisier than other parts. Ocean acidification alters the reproduction in some species. Species that have or grow shells or have an exoskeleton of calcium carbonate like prawns, molluscs, gastropods and corals. With animals without protection are most vulnerable to get eaten or attacked by predator, this means that there will be rapid changes throughout the food chain. Furthermore,…

At first glance you might think they are from out of this galaxy, you might think they are gross,stenchy ,or even rodent like, but in the end they will smell and taste like a dish from the last supper. Deep in the scorching southern states of America you can find them in every muddy, muggy swamp. I’m not talking about alligators or even turtles, that’s right I’m talking about the little red creature called a crawfish. Or better yet in the backwoods referred to as the “mudbug.” If you ask any…

The most significant lesson of a story is found in its ending. Children’s stories often give the impression that good always trumps evil, and as such, the hero always wins. The stories one encounters when they are older have more critical and realistic perspectives on certain situations. 1984 and Elysium are excellent examples of this. Both of the protagonists in these works are anti-heroes who struggle to fit in and thrive in their societies. They do not achieve their goals merely because they…

The body of the cockroach is elongated and segmented. It is dark brown or reddish brown in colour. Like most different insects, cockroaches have an exoskeleton, which means their skeleton is situated outwardly of their bodies. The exoskeleton is thick and hard made up of calcareous plates called sclerites and it is covered with wax impermeable to water. It shields the body from loss of water and gives unbending nature and surface to connection…
