Crustacean

floating through liquid heaven, soft illumination of ever changing colors, the aroma of salt water, a hint of wood from the floor and bench style seats. Entering the aquarium, visitors are greeted by many specimens of salt water inhabitants; fish, crustaceans, plants, and the obligatory sharks, the infamous predator of the ocean. The shark is not unlike predators found on the casino floor, which are concealed as gaming tables and…

Neoceratodus – * Neoceratodus is commonly known as Australian lung fish. *It is described as “living fossil” as it has undergone little changes during nearly 300 million years. *It is found in rivers and pools of Australia.…

he Red Lionfish is eye catching but venomous and dangerous fish native to the west Pacific. This fish can grow up to 45cm or 17.7 inches in length. These fish are known for their beauty and their venom, they are also aggressive feeders and huge breeders. The Red Lionfish could possibly end up in the United States Atlantic Coast also the Gulf Of Mexico if the precautions are avoided. If this fish enter these waterways it would potentially end most life in the oceans and make it difficult for…

Chitosan is a natural linear amino polysaccharide gained from chitin which is, after cellulose, the second more common biopolymer on earth. Chitin is the primary component in the shells of crustaceans such as shrimp, crab, and lobster. Chitin is present in crayfish, insects, and vegetal species mainly in the walls of fungi. These species require nitrogen for nutritional cycle. Chitin has been sourced from different originate and its composition shown in table 2.1 (synowie). Small quantity of…

which have pacemakers as part of the nervous system found outside the heart. Vertebrates and molluscs have myogenic hearts, where the pacemaker is composed of specialized cardiac muscle within the heart. Daphnia is unique as it is a cladoceran crustacean reported to have a myogenic heart. To test this, use drugs known to change heart rate in myogenic hearts and observe if they have the same influence on Daphnia. Methods: Used a modified pipette to retrieve Daphnia from cultured jar, then…

attracted to it. The pillbug, was originally native to the Mediterranean, but has since then been introduced to different environments and habitats in other countries such as the United States (Holland A., 2014). The pillbug is not an insect, it is a crustacean, which is an arthropod…

with β-(1-4)-linked N-acetyl-D-glucosamine. Found in the exoskeletons of crustaceans (crab, shrimp, lobster, insects) & molluscs, as well as the cell walls of algae and fungi, chitin is the second-most naturally abundant polysaccharide after cellulose [1, 2]. Chitin occurs naturally in the polymorphic forms: α, β and γ. The α-polymorphic form of chitin is the most abundant in nature, present in the strong exoskeleton of crustaceans [6]. α-Chitin forms tightly compact anti-parallel chains,…

The blob fish has always been dubbed "the world's most disgusting animal", but to me it's one of the most wonderful creatures ever tob grace the earth. The blob fish or in scientific terms, the "Psychrolutes marcidus"live in the deep waters around the coasts of Australia and Tasmania. They live in waters of 80 times the normal presure of sea level. Normally any creature at that depth would be crushed and die, but the blob fish has no bones. It's body is entirely made of strange gelatinous flesh…

Before the oil spill came Hurricane Katrina. Much like the movie Forest Gump, the aftermath of Hurricane Katrina saw that many fisheries were destroyed and although there was more than one boat left it did have a major impact on the shrimp industry in Louisiana. Because the supply went down for shrimp in the area the demand went up. This caused a higher price and higher equilibrium intersection although it would not be as high as one might think. Demand is interesting in this case because one of…

Zebra mussels An invasive species is any sort of fungus, animal, or insect that is introduced into the ecosystem of another country they are not native to. The zebra mussel has a pattern similar to a zebra. Zebra mussels are the size of a thumbnail. The zebra mussel has clean the water because they can filter up to one liter of water per mussel. Zebra mussels strain the water for food they eat in order to survive. The zebra mussel has been known to clog up drain pipes and being in big clumps on…
