Describe how human impacts are causing many species to become endangered or go extinct. Humans do a lot of bad things, that cause many species to go extinct or become endangered. One of the biggest problems is human predation. Humans do a lot of harm by hunting. They erased the megafauna mammals of the last Ice Age, decreased the population of whales and other marine mammals, and wiped out the Dodo Bird and the Passenger Pigeon. Another problem is that animals lose their habitat. Mostly, animals

The Red Snapper is also known as Lutjanus campechanus, they are pink to a red color (Louisiana Fisheries). They are commonly known as the North American Red Snapper, Snapper, Genuine Red Snapper. Their color starts to fade off under their bellies (Louisiana Fisheries). Some key characteristics are their red eyes, and their anal fin pointed than rounded. (Louisiana Fisheries). They can be found in the Gulf of Mexico and the Western Gulf (Louisiana). They can weight about anywhere ranging from 10-50

The scallop industry is growing in North America with the aid of Japanese technology and recent grants to adapt aquaculture techniques to the waters off the Eastern coast of the United States. However, Árni Kristmundsson and Mark Andrew Freeman have discovered that the common whelk carries a parasite which is deadly when it infects scallops. Scallop aquaculturists will need to remain vigilant to the threat. Scallops: seafood with a shell A scallop is a type of saltwater clam or mollusk with a shell

"There is nothing to throw away from a whale except its voice" (Arader, 2012). This ancient Japanese proverb demonstrates the depth of whaling within the Japanese culture throughout the ages. According to the Kijoki, the oldest chronicle in Japan recording the ancient Japanese history; the first emperor of Japan used to eat whale meat and fishing villages built whale monuments to celebrate whale hunting and shrines to worship the whale as well (Facts About Japan, n.d.). Similarly, whaling has a considerable

1911, Southern sea otters swam on every coast near the Pacific, Including the Sea of Japan. They lived in large kelp forests near shores and would usually stay on the surface of the water only diving when food was necessary. Being the most important part of the food chain, sea otters kept anything that would eat the seaweed like snails, and sea urchin populations in check so the kelp forests wouldn 't die out. Southern sea otter populations near the west were unknown, but the American east coast

The ocean is constantly in motion. The energy that arrives into the oceanic system on the planetary scales create large scale mean flows that are constantly breaking down into smaller scales features. The most important source of energy is the differential solar heat, warmer in the equator and colder in the poles. With the water transport, also heat, nutrients, salt, organisms and chemical particles in the ocean are moved, regulating the planet whether, climate and marine ecosystems. Both large scale

Environmental Sciences Assignment No. 01 Assignment Topic: “Ocean Acidification” Submission date: Jan 31,2015. Submitted by: Mahneem Fazal Submitted To: Prof.Dr.Faiza Shareef OCEAN ACIDIFICATION The stuffing of carbon dioxide in our earth’s environment is mirrored by an increase in the amount of carbonic acid present in the oceans .The sea water absorbs carbon dioxide, the reaction occur and the pH of the sea water decreases the carbonate ion concentration in the water and the

sea levels will be continuously increased by 20 centimeters in the 21th century if the situation of the environment does not change over the next few years. Additionally, as the emissions of greenhouse gases into the air, the ocean absorbs the toxic gases, thus making the ocean more

The Striped Pyjama Squid The striped pyjama squid is a very poisonous cephalopods out of the few that wander across the ocean bottom of indo- Pacific Oceans. Lots of scientists think that the black stripes on the Pyjama squid gives away its venomous attributes eliminating many predators. Also when they turn a dark purple with black stripes it give away its venomous attributes. Even though the name says squid ,The Striped Pyjama Squid is actually a species of cuttlefish, a multifaceted animal

Ecology and behaviour The southern right whale (Eubalaena australis) is a medium to large baleen whale, reaching a maximum length of 17.5m. Colour patterning is variable, ranging from black to grey-brown (Harcourt et al. 2012). Distinguishing features include a rotund body with no dorsal fin and callosities (caused by colonised cyamids, small crustaceans, on keratinised skin patches) on the head (Harcourt et al. 2012). Each individual has a unique callosity pattern that occurs a few months after

Imagine laying on a private beach right now in California. You are sitting in a comfortable lawn chair with a front-row seat to the Pacific Ocean. You have waiters bringing you any kind of drink or food you want, and the sun is making you golden tan. Now, imagine the thrill you get while being on a roller coaster. The sun is beating down on you while you are standing in line, but the wait for the exhilarating roller coaster is worth it. I was able to experience all this and more on my trip to Los

GRAY WHALE FACTS 1. Seasons for whales can be broken down into two primary seasons: mating season and feeding season. 2. Every year various species of whale travel several thousand miles to mate and reproduce offspring. 3. During mating season these whales will travel towards the equator to take advantage of the warmer climates. 4. Depending on the species of whale mating season can vary, but it typically occurs during the colder fall and winter months where whales can take advantage of the warmer

pacific maritime fur trade in 1969, sea otters were hunted until they were almost extinct. After that incident, sea otter hunting was prohibited by international treaty in 1911, because of this a dozen remnant colonies survived. While the North Pacific Ocean recovered at rates of 17-20% in the first year, the population in California hasn’t grown at more than one-third of that rate and they are currently listed as threatened under the Endangered Species Act. Even though the sea otter population in California

traveling into the seven seas and makes a claim to draw attention towards the health of our oceans. First, Pugh describes the litter, plastic bags, bottles, cans, shoes, and clothing on our ocean floor. However, Pugh was even more shocked about what he didn’t see, no sharks, no whales, no dolphins, all living life had been fished out (Para 4-5). Pugh says that over 100 million sharks are fished out of the ocean every year (Para 7). Pugh then proceeds to give an analogy about the Serengeti. He says if

Climate change affecting Penguins Penguins are a flightless bird that predominately lives in the southern hemisphere of the world, from the tropical Galapagos Islands to the Antarctic continent. They vary in sizes, the biggest being the emperor penguin which stand approximately 3 feet in height; and the smallest being the little penguin standing approximately 16 to 18 inches tall. All penguins are counter shaded, which means they have a white coloration in the front (ventral) surface and a dark

large area in places far from the equator, and it 's energy is concentrated on a small area in places at the equator. Therefore, places closer to the equator have a warmer climate, while places farther away from the equator have colder climates. 2. Ocean currents affect climate because it 's temperature affects the temperature of the air that passes over it.Therefore, that air can get hotter or cooler which might give a certain region a milder or damper climate. 2. a) For example, since the Labrador

After a plethora of studies made we know quite a bit about the ocean and the creatures that live there. We know who is the prey and who is the predator, what temperature some live in, and where they live. We know so much about the ocean and its inhabitants, but we also don’t know enough. There is more in the ocean than the things we’ve seen and studied. There’s things deep down in the ocean so deep that light from the sun doesn’t even reach it. In this deep abyss, there lives fish we have come to

Quinquecirrha: Sea Nettle. Animal Diversity Web.
