1 The sea otter is endangered because of oil spills in 1977. Tons of otters where hurt and were sent to the Marine Mammal. Under state law, southern sea otters are "fully protected" mammals. Southern Sea Otters are one of the smallest marine animals. Their fur is thick but soft when dry but in cold waters the thickness keeps them warm. The thing they eat are sea urchins, abalone, mussels, clams, crabs, snails and at least 40 other marine species. 2 Sea otters exhibit numerous adaptations which help them survive in their challenging marine environment. Long whiskers help them to detect vibrations in murky waters. Did you know that the sea otter is part of the weasel family and is the second biggest? Mating happens all throughout the year. Sea
Deborah Butterfield's "Otter" (2014) horse sculpture expresses a realistic display of beauty and craftsmanship because of its life-size image, the symbol of strength and the spirit it exerts where it is displayed at the Art Hotel in Denver, Colorado. "Otter" is a massive horse, standing at the entrance of the hotel, gazing toward the patio, looking as if it is going to trot right out the patio door. Deborah, born in San Deigo, California now lives in Montana and Hawaii. Montana and Hawaii have provided Deborah with the resources to create numerous horse sculptures, beginning with natural twigs and stems from the area. These tree stem creations are then constructed into free-standing, life-size bronze sculptures. The artist says, "I first used the horse images as a metaphorical substitute for myself-it was a way of doing a self-portrait one step removed from the specificity of Deborah Butterfield".
Origin - The Maine Coon is a natural breed, however currently the actual origin of the Main Coon is still underway. The "myth" of the Maine Coon coming about from the mating of raccoon and domestic cat is amongst the most popular. Although this is genetically and scientifically impossible to achieve, it first came about to be believed due to its unique brown raccoon-like markings and big bushy tail. "Maine Shags" were the name given to those that had markings any other color besides the brown coat. Theory of Maine Coons coming about from Viking's bringing these animals over into North America has been one of many popular theories. However, the most common theory is that of Marie Antoinette. Many believe when she tried to escape to North America, but did not succeed, she had left her long-haired cat on board, which then came to North America and bred
Everyone loves the Florida manatee because they look like big puppy dogs with a cute endless smile. In addition, they are beautiful creatures that bring a smile to every face that sees them floating along in their natural habitat or in the local aquarium. Undoubtedly, the Florida manatee is one of the friendliest species in the world even though they are huge animals weighing up to twelve hundred pounds and reaching ten-foot long. Despite what this gentle creature has been through at the hands of human beings, the Florida manatee looks as happy as ever when they are sighted feeding in their natural environment. However, the manatee population is being threatened and needs help to prevent further decline. The reduction in the Florida manatee
The sabertooth cat, also known by its scientific name Smilodon Fatalis, is considered a true form fossil. A fossil is considered a true form fossil when scientists recover fossils of the actual animal or animal part. These bones were oftentimes subjected to physical processes while still on the surface. These processes include heat, cold, wind and rain.
Mutualistic relationships occur between eagles and farmers when farmers begin to plant crops in their fields. When crops are planted, prey are attracted to the field to eat. Bald eagles will surround fields to prepare to eat the prey that come in. The eagle will eat the prey that are coming into the field benefiting it by providing energy to the bird, and the farmer benefits because his crops are protected and have the ability to
Within the state of Florida there are dozens of individualized, non-profit organizations making an effort to help the local wildlife. The local land and marine wildlife includes birds, geckos, frogs, snakes, panthers, manatees, sea turtles, fishes, sharks, corals, lizards and many, many more. Florida State is located on the Southeastern tip of the United States providing a unique opportunity for conservation of salt-water animals. While there are animal conservation efforts taking place all over the world, this essay will focus on two animal species that humans are specifically trying to save in Florida State. The two main animal species of focus are manatees and sea turtles.
Narwhals are not endangered, but they are nearly threatened. During the spring, summer, and fall Narwhals are hunted the most. Narwhals are also considered as the animal most threatened by climate change (Felsinger, 2008). With Narwhals being sea creatures, it would give them greater risks for becoming endangered and threatened. Narwhals are also threatened by the industries on the waters, like the oil, gas productions, and commercial fishing. By means of hunters, weather changes, other sea creatures, and even being close to populated areas, Narwhals face greater chances of being harmed or killed.
Introduction Sea otters (Enhydra lutris) are marine mammals capable of spending their entire lives in water. Being carnivorous in nature, they feed on sea urchins, crabs, fishes, mussels and clams. They are referred to as keystone species due to their profound impact on marine ecology. The interaction between sea otters, sea urchins and kelp forests has been studied as a model for the impact of predator-prey interactions on community ecology. Sea otters are keystone predators, whose presence has a far-reaching influence on the marine food web by affecting the populations of sea urchins, which indirectly affects the populations of kelp forests & other marine organisms.
sea otters are from the kingdom animalia. Sea otters are stouter and have large rib cages, smaller tails and muzzle than other species of otters. Yet sea otters posses the fine, dense fur coats characteristic of the Mustelidae. Their forefeet are small and dexterous with retractile claws and the flipper like hind feet are broad and webbed. Sea otters once was abundant along most coastal North pacific ocean. That was before fur traders hunted them for their thick ice, luxurious pelts. By the year 1900, sea otters were nearly extinct . Protected since 1911, alaska sea otters have made a comeback. There lifespan is 10-15 years. Great white sharks are the primary predator of sea otters and occasionally eaten by coyote so the predators that the
Hawaiian monk seals, Neo Monachus schauinslandi, are no ordinary species. They are Hawaii’s state mammal and are currently endangered. The Hawaiian Monk seal is rare because of many factors, which include overhunting, getting trapped in fishing nets, and overhunting of their favorite food, lobsters. Because of their rarity, the Hawaiian Monk Seal is a main attraction to tourists all over the world. Found in Hawaii, this monk seal is one of the two species left of the ancient seals. Grouped into the earless seal category, the Hawaiian Monk seal has two other cousins, the Caribbean Monk Seal (extinct), and the Mediterranean Monk Seal (critically endangered). The Hawaiian Monk Seal has a lifespan of 25-30 years, weighs 500-600lbs,
marine, either threatened or endangered. Under these terms species could no. longer be hunted, collected, injured or killed. The northern spotted owl falls under the more serious condition of being endangered. Also, the bill forbids federal agencies to fund or carry out any activity that would threaten the species or its habitat. It is the latter part of the bill that causes the controversy.
For years poachers have hunted these animals and slaughtered them in order to obtain there amazing water resistant coats. By the 1900’s there was a treaty signed to protect all of the sea otters, and even after Japan withdrew from the treaty Canada and the United States still kept it in effect. Even after the poaching stopped the pollution continued. Sea otters find themselves submerged in the giant oil spills that the tankers cause.
However, they began to go extinct when North America merged lands with the Southern counterparts, allowing placentals to move into South America and largely outcompete them (Moskowitz ,2010). Placentals now occupy one of the widest range of environments from marine to terrestrial. In order to thrive in the environments they are subjected to, eutherians have evolved various structural adaptations. They vary in size from shrews to whales. Being housed largely in tropical Asia, shrews (Eulipotyphla) are terrestrially adapted to dig burrows to hide from predators and forage for food with their reduced body size. In contrast, whales (cetacea) are the largest creatures dominating deep oceans. With its enlarged body size, its stomach is able to contain one tonne of krill for feeding (WWF, 2016). Contrastingly, the marsupials like kangaroos and koalas, as well as monotremes including the duck billed platypus and spiny anteater, all remained and possesses similar body sizes, completely lacking diversity compared to the
Wolves were once also native from Iowa. They remain on the endangered species list because of their low numbers. We have records saying that the last wolf that lived here was all that way back in 1925. There has only been one wolf seen since then and it was shot all the way down in Buchanan County. That was the first wolf seen and killed since 1925 that we have on record. The wolves are no longer here because in the 1900’s people were killing them off for their pelts that they used for currency or trade. We also killed them because people were very scared of them because they were mean and they usually run in numbers, known as “Packs”. There’s also a little creature from Iowa. The river otter once was full in this river. They weren’t just killed off here it was large parts of central and western part of The United States. That took place during the Mid-twentieth century. The otter’s were abundant during the European settlement. We killed them off again only for their pelts. After about 1890 in iowa they only existed on the mississippi river of
In the world today there are about five thousand endangered species. Around one specie dies out every year. Some animals become endangered because people are killing them for their horns, as in the case of the Black Rhino of Africa. Others become extinct because pesticides are put on the food we eat, causing the animals that eat the insects off the plant to become contaminated, which causes their predators to become contaminated, which often affects the shell of that organism?s egg. Here is a list of the endangered species, 91 endangered birds, 76 endangered mammals, 36 endangered reptiles, 21 endangered amphibians, 115 endangered fish, 70 endangered clams, 35 endangered snails, 44 endangered insects, 12 endangered arachnids, 21 endangered crustaceans, 594 endangered flowering plants.
