Sea otters are cute but fierce animals.They are called the sea otter but their scientific name is Enhydra Lutris.They are mammals not a fish or amphibian.The sea otter is black and white the face is white and the body is black.They have a very slim to move in the water faster.They have webbed feet to move faster and escape predators like a bald eagle and a killer whale.The sea otters nickname is “The old Man of the off the Sea”.They are called that because, when they get older their fur starts to turn a white or a silver color. Sea otters live in or by the coast of the Pacific.Some live in lakes and rivers.They live in the water or near the water.Otters live in shallow coastal waters off the Northern Pacific.Places like the coast of Washington,Oregon and California.The otters eat clams ter and sea urchin.They dive in the water to catch their prey. They use their forpaws to grab it.They use rocks to crack the shell open.In conclusion they live in northern coastal areas.They eat sea urchins,eggs,frogs and clams and use rocks to open the shell. …show more content…
The largest raft ever seen contained over 2000 sea otters.They sleep and take showers together.In conclusion their black fur helps them blend it with the
Growing thick feathers/fur- therefore stopping heat loss by convection as fur and feathers trap air which then acts as an insulator, fat/blubber which as an insulator, oily or greasy skin which would make the animal waterproof and stops water from entering layers of air therefore maintaining insulation layers, dark skin to absorb more light and heat (black absorbs light, white reflects light, th...

Orcinus orca is the scientific name for the massive marine mammal. Orcas are not rare, but have declining numbers in some areas (Martin.) Orcas are found from the Artic Ocean to the Antartic Ocean. (Britannica) They belong to the Delphinidae, or dolphin family, which is the largest of their species. Female orcas grow to be at the most 15 feet, and weigh up to 4 tons, but the males can grow as large as 20-30 feet, and weight up to 8 tons. (Martin) The color of the orca is white in some spots, black on the majority of the body, and gray just behind the dorsal fin. It is white on the chin, belly and the eye. The white patch above the eye is usually mistaken for the eye, and may confuse their prey, but acts as a camouflage for the eye. The name “killer whale” makes people tend to believe that this is a viscious man-eating mammal, yet it is one of the most shrewd, docile and playful species of the marine mammals. The orca is sexually mature at 10-15 years of age, much like humans, which is 12-13 years of age. They tend to mate year round, and is able to have a calf every two years. It is interesting to know that lactation of the mother lasts 12 or more months (Wynne.) The life expectancy of orcas is 45-50 years of age.

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. When oil gets into their fur is causes it to no longer be water resistant, therefore most sea otters die because they freeze to death. If they are in the warmer parts of the world, like California then the oil causes death from its toxins when the otters are trying to clean themselves. Oil spills and the garbage in the water are causing tons of marine deaths each year.
Though any Ocra can mate with another, behavioral adaptation create a form of speciation. Within the pod all Orcas speak a distinct dialect. Like humans, Orcas don’t possess just one language. An Orca from one pod would not be able to understand and communicate with an Orca from another, making mating difficult between the two of them. Leigh Dayton, the curator of marine mammals at Vancouver’s Public Aquarium, discovered this phenomenon by “listening to the two main communities of killer whales that were then divided into pods, each with its own dialect” (Orca Social Structure and (Whale) Dialects, 1). Captive Killer whales live in tanks with a “fake family” that they can’t communicate with due to different imprinting and behavioral adaptations.
Killer whales are some of the biggest marine animals found at sea. Scientifically killer whales are called Orcinus Orca and they are the biggest dolphin found in the dolphin family. Killer whales are primarily found in the Pacific Northwest, along the coast of northern Norway in the Atlantic and around Antarctica. Some killer whales are also found around Florida, Hawaii, Australia and some other places. A lot of the Orca are found mostly in the Antarctic and Arctic areas of the world. The habitat of a killer whale is usually cold water. Some living factors are fish, sharks, seabirds and some underwater plants and some non living factors include water, floating ice, rocks, kelp, etc. Killer whales primarily prefer cold climates and they occasionally found in warm climated places like the Mediterranean Sea, the Arabian Sea and some other places.
The diet of the Bottlenose Dolphin varies depending on geographical location and even water depth. Bottlenose Dolphins that live inshore will typically feed on fish and other invertebrates that are found near the shoreline (Reynolds). On the other hand deep-water Bottlenose Dolphins feed on squid and fish (Reynolds). Bottlenose dolphins along the U.S. Atlantic Coast typically feed on the following: Atlantic croacker, spot fish, and silver perch (Reynolds). Bottlenose dolphins typically choose prey between 5 and 30 cm in length; adult bottlenose dolphins eat approximately 4% to 6% of their body weight in food per day, while a nursing mother's daily intake is about 8% their weight. (Reynolds; "Diet & Eating Habits"). Although Dolphins do seem to show preferences for certain foods, they lack a sense of smell and do not have taste organs (Cozzi 344). Food is ingested whole rather than being chewed, which indicates that food preferences are not determined by “conventional” senses (Cozzi 344). Dolphins use their sharp teeth to grasp prey, rather than chew, and the tongue to maneuver prey down the throat whole (Jenkins). Although they don’t chew food, they may break up their prey by shaking it in the air and
Ocras usually migrate with their food, and they also have seasonal migrations. (Sea World). The food they eat is fish, sea lions, squids, penguins,sea turtles, sea birds, seals, baleen whales, other toothed whales {dolphins}, walruses, sea otters, sharks, the can also eat humans, polar bears, reptiles, mooses, and other killer whales [that are dead](Sea World)(National Geographic). They are carnivores (National Geographic). Killer whales do not chew their food they swallow their whole or rip off chunks. Ocras hunt in pods and to confuse their prey they herd them to the top of surface then attack. They can also jump on land to get their food. Killer whales have cone like-shaped teeth that are thre...
Bottlenose dolphins have slick and rubbery skin with no sweat glands or hair. Their epidermis is ten to twenty times thicker than that of other mammals. It can be replaced every two hours, which is nine times faster than human skin. The peeling of their skin helps to reduce drag when they swim. The skin is dark gray on their backs, and fades to white or pink on their bellies. This coloring is called countershading. From above the dolphins blend in with the dark water below, and from underneath they blend in with the sunlight. Countershading helps dolphins hide from predators and prey (Bottlenose Dolphins).
Sea horses can camouflage themselves to help survive in their environment. In paragraph 3 of "Hold Your Sea Horses!" sentence 3 states, "They can change colors to camouflage themselves, and feature bumps called tubercles that also help them blend in." Sea horses can blend themselves in to help hide themselves from predators, and also to help them not be seen when they are stalking their prey.
The role of the sea otter (Enhydra lutris) as a keystone species has been studied for years. Studies have strongly discussed the function of this animal that, though few in number, have created large impacts in the ecosystem in which it inhabits. Their main choice of habitat lies in kelp forests due to the kelp’s effect on the reduction of wave action and their closeness to rocky shores which provide habitat for otter prey (Schiel and Foster, 2015). Sea otter impacts can be seen through the phenomenon of trophic cascades. Within the kelp forests, otters are the dominant predator, consuming many species of invertebrates such as sea urchins and abalone (Schiel and Foster, 2015). As the only marine mammal without blubber sea otters have
Evolution can be defined as a developing process, where an animal or plant gradually becomes a more advance and multifaceted form. Examples of evolution include natural selection and mutations. Throughout history our planet and the species found on it were required to evolve to survive. Thus, leaving the best possible forms to survive and thrive throughout history. This process took time and has produced many variations, but the common result is species that became enhanced. There are many different aspects that have evolved, however the skin is the main focus.
The Blue Whale got it’s name for the color it possesses. Although they have the color “blue” in their title, they are actually a blue-gray color and only looks aquamarine in the ocean water. The Blue Whale is also known for their sulphur color because it is the color of their undersides. Although they are blue, there are some color variations that help us identify the whale individuals. The Flippers may be a light color or just white, and the underside of the fluke is dark. In the Northern Hemisphere, diatoms attach themselves to...
