Sample writing: Sedna was a lovely and beautiful Inuit girl and she didn’t want to get married because she loved her father very much and didn’t want to leave her father alone. But her father told her that she must marry a man. So the next day Sedna agreed to marry a stranger, who promised her a good life. But when she followed the man to his place, she discovered that her husband was a bird! Sedna felt so unhappy that she cried every day, calling her father’s name. When her father heard the crying of his daughter, he decided to help her to escape. When the bird man found that his wife was not there, he was so angry that he caught up with the canoe, which Sedna and her father were paddling back, and caused a sea storm. Sedna’s father was so frightened of the bird man that he threw Sedna into the sea. As Sedna sank to the bottom of the ocean, she became a sea goddess. From then on, The Inuit believe that Sedna has power over the animals in the sea, so they show her great respect, especially after they catch sea animals.

文化背景知识 Oceanic seahorse Fragile and mystical, the oceanic seahorse (Hippocampus kuda) is probably what you see when you close your eyes and think of seahorses. While not the most exotic species of seahorse, it is a classic representation of a beautiful and fascinating fish. You’ll see many types of seahorses at Shedd. Oceanic seahorses may be yellow, deep red, brown, or black and may be blotched or banded. They can reach about 7 inches in adulthood. The oceanic seahorse is also known as the common seahorse, but the sad truth is that all seahorses are becoming less and less common. And it’s precisely their ethereal, otherworldly charm that has gotten them into trouble. We’ve been enchanted by these creatures for millennia. From practitioners of ancient Chinese medicine to tourists in Florida, we’ve believed their magic gave us wondrous things — arthritis cures, love elixirs, even key chains. Now, because of that, they face a high risk of extinction in the wild. Seahorses cannot produce enough offspring to replace the huge numbers fished for medicines, pets and souvenirs. There are several reasons for this. First, they are monogamous, and if one of the pair is captured, it can take a long time for the remaining partner to mate again. Second, the striking ringed armor that protects seahorses from many predators does not develop until they’re adults so perhaps only two in a thousand juvenile seahorses reach adulthood.
Green Sea Turtle—Characteristics Name
Green Sea Turtles get their name from the color of their body fat, which is green from the algae or grasses they eat. The Hawaiian Green Sea Turtle population, is known by its Hawaiian name Honu History
Green Sea Turtles are reptiles whose ancestors evolved on land and returned to the sea to live. The first turtles appeared during the Triassic period, 245 to 208 million years ago. Fossils for the earliest known sea turtles appear in the Late Jurassic period, 208 to 144 million years ago. Turtles are one of the few species that watched the dinosaurs evolve and become extinct.
As reptiles, sea turtles possess the following traits: * They are cold-blooded, meaning they get their body heat from the environment. * They breathe air. * Their skin is scale Status
Now, scientists recognize seven species of these marine reptiles. The recognized sea turtle species are as follows: Greens, Hawksbill, Kemp’s Ridley, Olive Ridley, Loggerhead, Flatback and Leatherback. The Loggerhead Sea Turtle is listed as threatened, the Flatback is listed as vulnerable,
and all other species are listed as endangered. Green Sea Turtle populations of Hawaii are threatened and protected in Hawaii under state law. Populations of Green Sea Turtles off the coast of Florida and the Pacific coast of Mexico are listed as endangered. Green Sea Turtles are protected by the federal Endangered Species Act, and listed under the Convention on International Trade of Endangered Species (CITES). CITES makes it illegal to import or export turtle products.
Shell
In addition to their reptilian traits, all species of turtles except the Leatherback have evolved a bony outer shell, which protects them from predators. The Leatherback is the only soft-shelled sea turtle and is in a family by itself. The shell covers the dorsal (back) and ventral (belly) surfaces of a sea turtle. The dorsal portion of the shell is the carapace and is covered with scale-like structures called scutes, while the ventral portion of the shell is known as the plastron. Experts can identify species of sea turtles by the number and pattern of scutes on the carapace. The shell is considered the most highly developed protective armor of any vertebrate species. While most land turtles can retract their heads into their shells for added protection, sea turtles cannot and their heads remain out at all times. Color
Green Sea Turtles have green flesh. The carapace is olive brown to black, while the plastron is pale yellow to creamy white. The carapace is molted, variegated in color. Rarely will you find a Green Sea Turtle with a solid colored shell. Counter-shading of the shell conceals the turtle from predators, making it difficult to distinguish the dark carapace from the sea floor and the light plastron from the lighter sky. Size
Green Sea Turtles as hatchlings weigh about an ounce and have a carapace length of 2 inches. A sexually mature green sea turtle weighs 200-350 pounds with a carapace length of 2.5 feet. Adults grow to a carapace length of 3.5 feet and weigh an average of 400 pounds. One of the largest turtles that ever lived from the Late Cretaceaus period, 144 to 65 million years ago, reached a length of 9.8 -13 feet. Lifespan
The lifespan of sea turtles is not known. It is believed that Green Sea Turtles reach sexual maturity around the age of 25 years and can live up to 80 years of age. The long period of maturation helps to explain why it takes turtles so many years to recover from a population decline. Shape
Sea turtles are wonderfully adapted to life in the ocean. Their shells are lighter and more streamlined than land turtles. Front and rear limbs have evolved into flippers. These flippers make
sea turtles efficient and graceful swimmers, capable of swimming long distances in a short time.
