Water forms the ocean, produces the high density fluid environment and greatly affects the oceanic organisms. Sea water produces buoyancy and provides support for plants and animals. That's the reason why in the ocean organisms can be that huge like the blue whale and macrophytes. And the densities or rigidities of the oceanic organisms are ...
Video of Porcupine caribou in Becharof National Wildlife Refuge, Alaska. Ivvavik National Park protects a portion of the calving grounds of the Porcupine herd and restricts the number of people who may visit annually. During the calving in May, caribou are at their most vulnerable. Caribou management calls for preservation of calving grounds.
Caribou are still hunted in Greenland and in North America. In the traditional lifestyles of some of Canada's Inuit peoples and northern First Nations peoples, Alaska Natives, and the Kalaallit of Greenland, caribou is an important source of food, clothing, shelter and tools.

Marine life, sea life or ocean life is the collective ecological communities that encompass all aquatic animals, plants, algae, fungi, protists, single-celled microorganisms and associated viruses living in the saline water of marine habitats, either the sea water of marginal seas and oceans, or the brackish water of coastal wetlands, lagoons ...
From shallow waters to the deep sea, the open ocean to rivers and lakes, numerous terrestrial and marine species depend on the surface ecosystem and the organisms found there. [28] The ocean's surface acts like a skin between the atmosphere above and the water below, and harbours an ecosystem unique to this environment.
Some species are endosymbionts of marine animals and other protists, and play an important part in the biology of coral reefs. Others predate other protozoa, and a few forms are parasitic. Many dinoflagellates are mixotrophic and could also be classified as phytoplankton. The toxic dinoflagellate Dinophysis acuta acquire chloroplasts from its prey.
Sea water, in theory, could be used to help a fire. But, its salty components can do more harm than good, which is why firefighters typically avoid using it unless absolutely necessary.
Caribou are large-scale migratory animals and have been known to travel up to 50 miles (80 km) a day. The migratory activities of caribou are usually driven by weather conditions and food availability. [16] Changes in caribou migration can be problematic for Alaska Natives, who depend on caribou for food. [16]
