Bivalves

Biology Essay - Oran O'Sullivan One of the most dangerous and controversial contaminants today is tributyltin (TBT). Tributyltin is one of the most poisonous substances to be released to the aquatic environment today (Knutzen, 1995). The tributyltin compounds are a subgroup of the trialkyl organotin family of compounds (Extoxnet, 1996). The main use of Tributyltin is as a stabilizer in the manufacturing of plastic products, such as anti-yellowing agent in clear plastics and as a catalyst in poly…

Left unchecked, the sea urchins overgraze the benthic vegetation and the kelp forests. Kelp forests provide habitat for fish including “Irish lords Hemilepidotus spp., greenlings Hexagrammos spp., and the rock sole Lepidopsetta bilineata; Ayres” bivalves (including the rock jingle Pododesmus macroschisma; Deshayes), chitons (including Katharina tunicata; Wood, and Cryptochiton stelleri; Middendorf), limpets, crabs and seastars…

at all like atomic DNA, which is passed on from the two guardians, mitochondrial DNA is for the most part uniparentally acquired (with some outstanding exemptions). In creatures mtDNA is gone on maternally through the egg, with the exception of in bivalve molluscs where biparental legacy is found. In plants mtDNA might be passed on maternally, in a fatherly way, or biparentally. There is additionally prove for fatherly spillage of mtDNA, where the posterity acquires a large portion of their…

The cutest most microscopic critter in the deep ocean just might be the dumbo octopus. It has large, rounded fins on its body that resemble the ears of “Dumbo, Walt Disney’s animated elephant.” And like the adorable little elephant, the dumbo octopus uses those big “ears” to get around. It’s biome is the aquatic Marine. Dumbo octopus can be found typically in every ocean in the world. Although, the dumbo octopus is a deep sea animal that lives on the floor of the ocean at extreme depths. The…

Zebra mussels are a small bivalve mollusk that originate from Eastern Europe and Western Asia (kdheks.gov). Zebra Mussels get their name because, of their cream and black stripes on their shells. Zebra mussels have small dime sized, triangle shaped shells. Zebra Mussels in large numbers are known as colonies and can contain millions of individual mussels. They’re known as an exotic invasive species because they are nonnative to US waters. Unlike our native Kansas mussels, Zebra Mussels don’t…

Each species in the world have a specific job in our world, a niche, some species are important and get the title keystone. Keystone species have an important life, without them the ecosystem they live in will have a domino effect that will change the ecosystem or destroy it all together (Nancy, 2013). The Sea Otter (Euhydra lutris) are remarkable creatures in that they help keep their environment in check (Konar, 2000). The genus name Euhydra and the specific name lutris are both translated…

Zebra Mussels Invasive species are pretty common this day and age. An Invasive species is a species of animal living in an ecosystem it does not live in naturally (NISC, 2006). Usually, when a new species is introduced into the ecosystem through humans, it does not have any natural predator. This means the species invading the ecosystem can reproduce all it can, taking the ecosystem over. However, animals aren’t the only organism that can invade ecosystems. Plants do it often, and have bad…

20,000 Leagues Under the Sea by Jules Verne is a classic for the ages. Its crisp details of the oceanic life and its scenes of action will leave a reader breathless. Through the eyes of Professor Aronnax, we learn about ocean life and why Captain Nemo does what he does. Our main character is Professor Aronnax. Smart and well-known around the world, he travels with his servant, Conseil to teach and lecture about the marine world. Conseil, on the other hand, is quiet, and speaks whenever he…

The marine world is highly dependent on the activity of microbes in many different ways. Microbes in the ocean come in the form of autotrophs and heterotrophs and come in any of the three domains of Eukaryota, Archaea, and Bacteria. Members of these domains can range from all niches as producers at the bottom of the food change, critical gut microbes and decomposers. Arguably, somewhere these and more duties are most important is around the hydrothermal vents found at the bottom of the ocean.…

Mud flats are a vital type of marine habitat that provide several different functions for various marine invertebrates. They provide both permanent and temporary homes to small invertebrates including several species of worms, crabs, snails, and other benthic fauna. These organisms are responsible for the breakdown of organic materials often deposited here, as well as filling the role of prey for many predators that hunt in the shallow waters (Dyer et al., 2000). Mud flats are most often…
