Polychaete

Myles Lawary 4-4-17 Mrs.O’Connor Marine Science Barrier Reef The Barrier Reef is the largest reef in the world, and it is located in Australia. It is made up of different types of coral and fish, but sadly the reef is bleaching. Bleaching is the process of water temperatures getting too warm and as a result coral reefs can bleach. When water gets too warm, corals will get rid of the algae living inside

The Pompeii worm is related to the Polychaete which are marine worms. This worm can handle temperatures up to 80℃ and can length up to 13cm. Their back is coated in a bacterial mat that reacts as an insulation system. Not only is their back coated with bacteria, but their whole body is covered

Producers of Zoophycos traces are observed to be more dominant in the shelf and slope environments; but are found ubiquitously, and considered to have tolerated variable water depths, substrate grain sizes, food resources, energy levels and dissolved oxygen content. Nereites ichnofacies is characterized by abundant and variable intricate meandering farming and grazing traces. These features can only be achieved in stable environmental conditions with low energy, poor sedimentation, adequate oxygenation

The Japanese volcanic island arc known as the Ogasawara Archipelago enjoys a warm, marine subtropical climate and is free from the industrial overpopulation of mainland Japan. These islands are situated in one of the most highly active volcanic regions of the world, part of the Pacific Ring of Fire, and formed by the subduction of the Pacific Plate and the Philippine Sea Plate boundaries. The islands themselves were formed by eruptions of lava due to undersea oceanic plate convergence over fifteen

In the ever-expanding field of aquaculture, the demand and production of Atlantic salmon (Salmo salar) has increased substantially, having grown over six-fold in the last two decades worldwide (Howard, 2014; Murray, 2014). Increased emergence of parasitism and disease has met this expansion, particularly in areas where disease-control strategies are not yet locally coordinated (Murray, 2014). Salmon lice (Lepeophtheirus salmonis) have significantly impacted the salmonid farming industry since the

Imagine you’re out camping in a pitch black forest. The moon is hidden by the canopy of trees and you’ve left your lantern back in the tent. There is no way to see where you are going and panic begins to set. When all of a sudden the ground around you begins to glow and visibility has returned. What is the cause of this phenomenon? To whom or what should you be thankful for? This is known as bioluminescence, a feature that causes eukaryotic and prokaryotic organisms to illuminate. This is a rare

A fossil Lagerstätten is a form of sedimentary deposit that is of high value due to the fossils that it contains (Clarkson, 1998). The geological horizons containing these deposits were named by the German Palaeontologist Adolf Seilacher in 1985 (Nudds & Seldon, 2008), ‘Lager’ meaning Stratum and ‘Stätte’ meaning place (Allaby, 2013). Palaeontologists divide fossil Lagerstätten into two types; Konservant-Lagerstätten (Nudds & Seldon, 2008), or conservation deposits, are horizons that show exceptional

The crown-of-thorns starfish (Acanthaster planci) is named for the brightly colored spikes that coat the legs. A. planci can grow up to 16 inches across and can have between 12 and 19 legs. The spikes coating A. planci hold poison that can cause temporary paralysis at the sting site and can also cause nausea in humans. A. planci can also regrow arms. At the end of each of the arms is an eyespot that can detect light and darkness, but can not detect color and shape (Fisher 2011). A. planci preys

having nowhere to go, having to find new resources and a new home. The BP Oil spill which happened in 2010 happened in the Gulf of Mexico destroyed many homes for animals.”The spill area hosts 8,332 species, including more than 1,270 fish, 604 polychaetes, 218 birds, 1,456 mollusks, 1,503 crustaceans, 4 sea turtles and 29 marine mammals.”(Wiki) Those numbers are just the species and not each specific numbers of animals. The impact it had on the animals in the water had just as big of an impact for

Life in Extreme Conditions Planet Earth plays host to a myriad of exotic ecosystems and environments, both natural and artificial, from the deepest hyper-saline lake of the Dead Sea to the hydrothermal vents along mid-ocean ridges in the Pacific and even the nuclear radiated wastelands of Chernobyl. In these extreme environment where humans generally can’t live or would die there, organisms known as extremophiles flaunts life’s ability to exist inside the harshest of environments. In mankind’s
