Crustacean

Introduction The diversity of arthropods extends beyond the location factor alone as multiple influences such as humidity levels, atmospheric content and other environmental conditions contribute to their widespread assortment. Gaps in diversity indices do not only occur amongst insect populations residing at regionally distinct locations as these influences are also reflected in arthropod communities over small distances. Climatic conditions often lead to insect migrations and extinctions which…

Long ago there was a great vast paradise where all insects lived. Among these insects were the worms, the most easily frightened, and the most unwilling to try any new things out of all the insects; some may even say that these worms suffered from Neophobia. Everyday for breakfast, lunch, and dinner, the worms ate dirt. However they did not eat it happily; it was often that they would complain and say, “I am tired of eating dirt. It’s disgusting.” To which the older much wiser worms would say,…

Isopods are interesting creatures that have been decided to experiment upon as the test subjects. However, the term isopods, generally refers to the order Isopda but to be more specific pill bugs are a subcaterogy. Therefore, the classification for them are the family Armadillidiidae, which means that they have the ability to conglobate/curl into a ball, acting as a defense mechanism for them if and when they are in danger. Additionally, the best known and most investigated is Armadillidium…

One of nature’s finest peculiarities is the mantis shrimp, a crustacean closely related to the pistol shrimp. The pistol shrimp occupy the family Alphidae, while mantis shrimp are the most notable part of the broader order Stomatopoda (Duffy, 2003). Nonetheless, the groups are considered evolutionary brothers and the traits and instincts of the organisms are closely related, as both have the strength and agility to create cavitation bubbles as a direct result of their strike (Patek, 2004). In…

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…

The Homarus americanus also known as the true lobster, the northern lobster, and the Maine lobster play a imperative role in the ecosystem. They are a ample source of food for America and all around the world because fishermen harvest such preponderant amounts lobster. Sometimes they are over fished so places such as the European Union, Canada, the U.S, and New Zealand are starting the manage the amount of lobsters harvested so that fishermen do not deplete the source. The reason they are so…

Do Cnidarians replace their stinging cells once used? Many people are familiar with the Jellyfish sting. When a jellyfish brushes against someone and they feel pain, they are feeling the cells along the jellyfish's tentacles referred to as cnidocytes. These cells harbor tiny projectiles full of venom, called nematocysts. There are many questions about the sting of the jellyfish, the structures involved, and the venom delivered. Specifically, do Cnidarians possess any capabilities of…

Discussion: The purpose of this experiment was to observe the effects that salinity content had on the possible hatching successes of brine shrimp nauplii. It was also used in order to find the optimal salinity content and if that content was of high concentration, or that of a lower concentration. It was predicted that the Artemia spp would be much more positively affected, with higher percentages of live nauplii hatchings, in the water containing the lower amount of salinity content. The…

Striped bass eat a variety of foods, including fish such as alewives, flounder, sea herring, menhaden, sand lance, silver hake, tomcod, smelt, silversides and eels, as well as lobsters, crabs, soft clams, small mussels, sea worms and squid. The largest bass in Texas was caught on the Brazos river and it was 53 pounds. Stripped bass inhabit coastal waters up to 10 kilometers from shore and are often found in bays. In spring, they migrate to freshwater rivers and lakes to spawn. There are also…

Arthropods are made up mostly of crustacean about 50,000 known and divided into groups; Branchiopods, Maxillopods, Malacostraca and Ostracods. The Malacostraca is divided into five different groups, decapods, stomatopods, euphausiids, amphipod and isopods. Decapods include crabs, lobster and shrimp it’s the largest species. Decapod means ten to five pairs of legs most first pair are modified as large claws, called chelipeds. Most decapods hatch as a zoea but on some occasion shrimp can hatch a…
