Malacostraca

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 addition, both are within subcategories of the class Malacostraca. Stomatopoda is an aquatic order dwelling primarily in colonies in tropical shallow waters. Their grouping and dwelling capabilities are but one of the features setting Stomatopoda…

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…

Hey there, did you know there are seventy-five different species of stingrays? That's a lot! Sting Rays are also closely related to sharks. The manta rays are the biggest species yet. They can reach up to seven feet wide and a length of fourteen feet long. Their diet is crustaceans, planktons, and small fish. The manta rays like staying just above the seabed to get cleaned. They also have the largest brain of any sea creature, so they probably make even the average dolphin jealous. Manta rays…

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…

The purpose of this experiment was to be able to identify certain substances that the Armadillidium vulgare is attracted to or would be likely to move towards. The substances were three different liquids and three different solids. Another purpose of the lab was to learn the characteristics of an Armadillidium vulgare also known as a pillbug (Mader, 2013). The main topic was based on whether the pillbug would be attracted to certain substances, and the reason they’re attracted to it. The…

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 imperative is because lobsters are the cynosure of scarce fisheries all around the world and are frequently regional icons mainly because lobsters are some of the most researched animals on earth. Also research centers for lobsters have made enormous amounts of money yet still do not fully understand their role in the marine ecosystem and…

ANSWER: Because it is hard to float in water without any salt in it 3. What is Sera sick about? ANSWER: She’s sick of competing in the beauty contest that life is, sick of being a…

are ecologically diverse, filling the roles of benthic deposit feeders, pelagic and sessile suspension feeders, scavengers, predators. Crustaceans are morphologically diverse as well: segmentation may vary, limbs are typically more specialized than those of Trilobitomorpha and still vary among subgroups. (Robison and Kaesler, 1987) The diversity of crustacean morphology has resulted in a precise classification scheme. The class, Ostracoda, includes small crustaceans (typically less than 1 mm in…
