Crustacean

biological process by which an animal physically develops after birth or hatching, involving a conspicuous and relatively abrupt change in the animal's body structure through cell growth and differentiation. “Some insects, fishes, amphibians, mollusks, crustaceans, cnidarians, echinoderms and tunicates undergo metamorphosis, which is usually accompanied by a change of habitat or behavior”. (http://en.wikipedia.org/wiki). But this change has been incorporated to human’s life and an attempt is…

Blood is everywhere, in everyone, in all living animals. The type of blood and what makes it look how it does is all based on its composition. The uses of it are vital to all animals survival as it is the key component to living. Unknown to most, but the blood's composition must be kept at near perfect balance at all time for it to perform all its functions. Blood is a crucial part of an animal's existence. Without it, it could not survive. Blood has numerous types as well as appearances, and…

People have existed on earth for billions of years. Many species of animals and fish that do not have males as a part of their community, but instead, they have the ability to reproduce asexually. Even though males are not necessary for survival, Matt Ridley argues using different business references and nature examples to prove men are similar to animals by nature because that is how women bred them to be. Ridley uses a different style of writing to further prove his point of the essay. The…

hundred billion gallons a year of phosphorous laden fresh water to the saltwater sounds at the mouths of both rivers (Ferguson). This pollution wrecks havoc with the soft ecosystems there, causing vast amounts of algae blooms that kill fish and crustaceans. In 2011, a field study was done in the St. Lucie when the first super algae made its way to the saltwater canals, the death toll for the wildlife was estimated to have killed more than 1.2 million animals compared to the year before that only…

For anyone who has taken a walk around the nature, as his or her favorite thing, one could have look up to the sky and listen to the birds singing in the high, blue sky. Additionally, that person could have count the number of birds that were heading homes. Suddenly, the wind slightly swept through and whispered through the ears. Took in a deep breath, he or she could sense the taste of fresh air. The mind opened. What a time to be alive. However, time changed. In reality, the air that used to…

Hydrurga leptonyx, also known as leopard seals, are incredible creatures that possess traits of survival and adaptability. Their widespread residency throughout the Antarctic and some parts north of that combined with their diversified eating habits places them highly in marine mammals as a potential species to survive environmental changes. This essay connects an understanding of the population and foraging ecology of Hydrurga leptonyx with their future existence in relation to climate change.…

Lionfish Invasive Introduction Non-native species have be released and introduced all over the world, but nothing quite compares to the invasion of the Lionfish. Species invasions, such as the Lionfish, can serve as a major threat to native ecosystems by causing ecological damage (Côté, 2013). Finding out what these ecological damages might be and how to slow down the process is Pterois volitans & Pterois miles The fish commonly known as the Lionfish has two species, Pterois volians and…

The idyllic image of a nuclear family, although indistinct at first, comes to take a firm grasp on a myriad of different types of families, as gendered language seeps into their thoughts and actions. Through historical pressures and Western influence, one can view the significance of gendered ideologies in the Philippines having to be contoured and contorted in order to satisfy the restructuring of economy and politics from colonization; ultimately favoring a patriarchal reign in all political…

Previous knowledge of normal equilibrium potentials for various ions proved to be imperative information for deciphering our results. We referenced extracellular (Eqout) and intracellular (Eqin) concentrations (MM) of giant squid neurons to predict crustacean cells at rest, Eqout[K+]=20, Eqin[K+]=400, Eqout[Na+]=440, [Na+]in=50, Eqout[Cl-]=560, Eqin[Cl-]=40-150 (Purves et. al…

differs according to sex or age classes (Casaux, 2009). Juvenile seals normally feed on krill, while older seals consume seals, penguins, and other species (Hiruki, Schwartz, & Boveng, 1999). Generally, prey includes cephalopods, penguins, fish, crustaceans, other seals such as Southern Elephant, Fur, and Crabeater seals, and krill, which has been found to be the primary prey during the winter (Southwell et al., 2012; Hückstädt, 2015). However, the importance and prevalence of prey depends on…
