Crustacean

The green sea turtle, also known as Chelonia Mydas, is an endangered species. Sea turtles are targeted by people due to their meat, eggs, and shells. For people, this is a way of not only getting food but also an income source. Another factor that contributes to the green sea turtle endangerment is overfishing and poaching. Sea turtles are also used by some for ceremonies or even medicine. Technology such as propellers or getting hit by a boat can also pose threats to sea turtles, as the…

by a burning sensation that causes the host to put its foot into water for pain relief. Once there the female worm erupts through the skin and releases larvae into the water. These larvae are then eaten by a small crustacean called a copepod. This copepod is a free swimming crustacean that lives in natural water sources, and when that water is consumed without a filter the consumer will be consuming the infected copepod with it. The copepods cannot survive in the digestive tract, and upon death…

Welcome to the most colossal biome on Earth, the marine! This ginormous place on Earth is home to many plants and animals within its many oceans and three different levels. Pacific, Atlantic, Arctic, Southern, and Indian are the five main oceans on this planet. Each ocean is separated into three levels, known as euphotic, disphotic, and aphotic. The euphotic zone is also known as the sunlight zone, this is the top layer of the ocean and it receives almost all of the sun's rays. The next section…

help control the population of fish below them in the food chain. Research has shown that the decrees in shark population has had a major effect in the oceans eco system. Species Diet Most species of sharks eat the normal fish, meaning they eat, crustaceans, mollusks, plankton, krill, marine mammals and other sharks. Sharks also have an accurate sense of smell, this allows them so detect blood in the water from miles away. Population There are many types of sharks so it is hard to determine…

they are, this is an indication that one is derived from the other. In addition, embryological studies examining similarities during development of various species. For instance, the “similarity of larval stages supports the conclusion that all crustaceans have homologous parts and a common ancestry” (“Science”, 1999). Further, scientist Motoo Kimura has also supported Darwin’s theories in the field of molecular biology with his theory of molecular evolution, which consists of the gradual,…

This thesis revolves around the idea that monsters always escape because they refuse easy categorization (Cohen 6). For example, in the film Alien, the monster Ridley Scott created is part reptilian, part humanoid, and part crustacean. Monsters may have some sort of deformity or body part that prevents them from being classified. Thus, it is impossible to classify these organisms and they “escape” the margins of our coherent epistemological system of classification (Cohen 6)…

composed of phytoplankton and zooplankton which are on usually tiny animals found near the top in aquatic environments. Like phytoplankton , Zooplanktons are weak summers and often just sway along with the currents. The huge category of zooplankton crustaceans both the larval of larger animals. The small zooplanktons are single celled protozoans aka microzooplankton which eat the smallest phytoplankton. Jellyfish are classified as a type a zooplankton that both drift in the ocean have some…

above for color vision that allows them to see above the water and below the water at the same time, an average mudskipper can be measured around 7cm to 25cm. The diets of the mudskippers are carnivores and eat small animals that include insects, crustaceans, and worms. For some of the mudskippers time, the mudskipper sits motionless in the mud, waiting for insects to eat. They use their strong shoulder fins to chase the insects across the water into the…

Carbohydrates are the main source of energy for living beings; its consumption is vital to our existence. The Carbohydrates play various roles in our body; the main ones are the nutrition and energy supply. The body will use every trick to keep the fed cells, as the glucose supply cannot stop. Foods rich in carbohydrates, such as breads, cereals, rice and pasta, are an important form of energy for the body and, therefore, are very important to a healthy diet. However, when consumed in excess,…

asphyxiation, must be regarded as inhumane. The close quarters where farmed fish are raised means disease can spread fast, while contaminants and deadly pathogens can spread beyond the nets and get into the free fish swimming past. Sea lice, a type of crustacean that is easily incubated by captive fish on farms, have become a major problem and have been the reason for declining numbers of wild pink salmon, as well as the animals that depend on them for food, such as bears, and eagles.…
