Research Paper On Krill

The sea mink (Neovison macrodon) was a mammal from the eastern coast of North America, in the family of weasels and otters in the order Carnivora. The largest of the minks, it was hunted to extinction by fur traders before 1903, when it was first given a species description. Some biologists classify it as a subspecies of the American mink. Estimates of its size are speculative, based largely on skull fragments recovered from Native American shell middens, and on tooth remains. Some information on its appearance and habits was provided by fur traders and Native Americans. It may have been similar in behavior to the American mink: it probably maintained home ranges, was polygynandrous, and had a similar diet, supplemented by saltwater prey. Sea

On this image, we see the external dorsal side of a preserved crayfish. As part of the largest animal phylum the Arthropoda, the body of the crayfish is segmented, with jointed appendages and exoskeleton. The paired antennae (1) are long appendages located the front of the mouth and modified for help the animal to sense touch and taste. The antennules (2) are shorter, also paired with the same function but they also help to maintain balance. The chelipeds (3) are located on the front of the thorax, and they are responsible for defence and grasping food. On the at ventral part of the thorax, we found four pairs of walking legs (4), with these legs the crayfish changes locations on the bottom of freshwater lakes, streams and also on land. They

It’s a beautiful day at the beach, the sun is shining down on you as you float and drift on top of the waves. As you lay there without a care in the world, you are suddenly interrupted by a massive swarm of jellyfish; also known as a bloom. Not only does this send you into sudden terror, it also causes a much bigger threat to the ecosystem below you. The excessive growth of jellyfish swarm drastically lowers the population of fish eggs in the ecosystem. Because of this, fishermen lose millions of dollars. People in local communities are figuring out ways to solve this mass production.

The different types of seals are the Leopard Seal, Harp Seal, Gray Seal, Northern Elephant Seal, Southern Elephant Seal, Weddell Seal, Hawaiian Monk Seal, and the Mediterranean Monk Seal. Seals have quite a spread when it comes to their habitats. They can be found in the cold regions of the Antarctic, to warm, extremely sunny places. They are able to survive in the icy conditions due to the layers of blubber on their bodies that keeps them warm. The seals that live in colder regions are heavier in size. Seals are breathtaking, more people should educate themselves on seals so the seals can be

One of the most mystifying creatures of the deep blue sea, the cuttlefish is not a fish it is some squid-like mollusks. The cuttlefish has a large out stretched body with its mouth being surrounded by tentacles, giving it the nickname head-footed. Cuttlefish around the world varies from sizes of 15cm to 60cm and weigh from the range of 6lb to 23lb. This creature is found throughout the warm tropical shallows of the ocean to the cold depths of the deep ocean.in order for the cuttlefish to survive they are able to change their body color and they body texture to blend in with different marine environments, while being prey upon dolphin, sharks, seals, cuttlefish, and other big fish. The cuttlefish uses its ability of changing colors to hide itself

It is a very common photosynthetic dinoflagellate found year round in the Gulf of Mexico. These dinoflagellates have two whip like appendages that enable them to propel themselves through the open water. K. brevis thrive in warm waters with high salinity. The Gulf of Mexico meets these conditions perfectly which is where there is such an abundance of K. brevis in the area. The region where K. brevis blooms the most is along the West Florida Shelf, extending from Key West all the way to the Panhandle coast in the North. In this region, there is discharge from several rivers and coastal upwelling will often occur (Li and Weisberg, 1999). The currents in this area are influenced by win and tides, and the Continental Shelf contributes to the circulation. This zone is a shallow ecosystem that has a wide variety of communities and sections. These include mangroves, seagrass banks, and coral barrier reeds. This area is very diverse and serves the economy in more ways than one. It is important for commercial fishing and for tourism. It is important that the water quality remains in good condition because it is in this area that the Florida Keys National Marine Sanctuary, and the Everglades National Park are located. Blooming season in these regions typically begins around August and will last all the way through to early Spring, around March. More than 80% of K. brevis blooms have taken place in

It was interesting to read that the hypothesis provided by the scientists turned out to be opposite of what happened to Valley Creek. The macroinvertebrates were already living in a low quality creek full of pollution, so I would have also expected their population to decrease after introducing a predator to their environment. The crayfish reminded me of the keystone species sea stars, that I learned about through a lecture on communities and ecosystems. The study conducted on crayfish was similar to a study conducted on sea stars, except they were removed from coastlines instead of being added to see the effect they had. The sea stars were believed to have a negative effect on the coastlines since they preyed on mussels, but it turned out

Imagine living at the bottom of the sea with little food to eat and you are suddenly caught. You realize you are coming up through the sea. You are pulled out from the water and you are having trouble breathing. The fishermen throw you onto the deck of the boat and you suddenly realize you have just lost everything but then after the picture is taken they throw you back into the sea. You swim back to the bottom of the sea and see your mate and babies. The blob fish was allowed to do this because they respond to the environment, reproduce, gets energy, exchanges gases, and

They also prey on smaller fish such as skates, eels, herring, and cod. On occasion remains of larger mammals such as seals, moose, polar bears, and reindeer have been found in their stomachs. Its even speculated that these sharks ambush seals, with their ice holes being like beacons. Female Greenland sharks are ovoviviparous, meaning that they retain the developing embryo inside of their bodies to hatch instead of depositing it into the mud. While the gestation period is unknown there are usually 10 pups per litter that are about 90 centimeters

A Marine Biologist Will be a Right Careen Scientist for You ! Marine biologist are scientist that study water bodies, performing a number of duties that vary by the specific job. They may research experiment or create plans for action to improve and sustain aquatic life, healthy, and productive. Marine biologist spend many hours in oceans, lakes and rivers studying plants and animals, in addition to the time spent in the classroom learning about the sciences applicable to marine biology. Marine scientist study and analyze ocean ecology and aquatic life.

In 2004, the giant squid had been discovered in deep, inky waters (Schembri 1). These creatures had frequently been misconstrued as monsters throughout history, in sailors’ yarns, wives tales, and even official reports. With a length of 40 to 42 feet, the leap of faith does not seem so difficult. (Giant 1) Giant squids are not known anymore to sink ships like their Kraken persona, but they are extremely territorial, even fighting sperm whales to protect their homes (Coppens 4). Despite being capable of eating just about anything with meat on it, Giant Squids mainly feed on small fish and clams (Schembri 1). For millennia, the giant squid lived in the realm of legends. Its existence lied in the study of cryptozoology, or “the pursuit of wildlife

Antarctic krill (Euphausia superba) is one of the most abundant organisms in southern ocean, with a total biomass of hundreds millions of tons. It is a cold water species and they mainly feed on marine algae. Their lifespan is five to six years and they can grow up to six centimeters long. Atlantic krill start life as eggs that sink and hatch in spring. They develop though Nauplius, Metanauplius, Calyptopis stages and reach the fourth stage - furcilia - by winter. Antarctic krill that hatch at the depth of shallow Antarctic shelf (300 - 400 meters) can swim back to the surface water before winter. Therefore, furcilia are able to survive the first winter by feeding on algae and a small portion of zooplankton on the undersurface of pack ice before using up their stored supplies. Antarctic krill that hatch in water deeper than 500 meters may starve before they are able to swim back to the surface and find food to feed on.

Ever since a young age, I have been extremely interested in ocean life. Due to annual summer beach trips, I was exposed to aquatic life often as a child and became very comfortable in and around water. My interest in the ocean is the main reason that I can see myself as a marine biologist in the future. Another trait of mine that contributed to this career choice is that I enjoy working with others, but also work well independently. For this reason, I want career where I can collaborate ideas among my coworkers, but also work on independent projects or investigations. In addition, I will enjoy a career where I can interact with other people and animals, rather than work strictly in an office. I also enjoy science classes, including chemistry

Antarctic krill are one of the most recent sources of bio-inspired computing [15]. Krill are tiny crustaceans similar to prawns.(with large black eyes and are usually around only two inches in length). By volume, krill constitute a significant portion of living beings under the oceans [16] [15]. (The worldwide population of Krill has been estimated to outweigh the human population of the world). Krill are considered to be one of the most abundant and successful animal species on earth, and they provide the driving force behind the marine ecosystems of the planet. Many consider Krill to be the “fuel” that the planet’s marine ecosystem runs on; without them, most of the life in the Antarctic would begin to

The Equation (7) suggests that if the distance between two krill individuals is less than the calculated ds, then they should be considered as neighbors, and thus, they could influence the movement of one another in a direct manner. An analytical review of the Equation (7) also reveals that the mentioned formula have a tendency to calculate higher ratios of ds for those krill individuals that are separated from the herd (placed in a low-density position). This way there is a better chance that the neighbors of such krill, could make a greater impact on its motion so that it could decrease its distance from the
