I'm Michael C. Clark Naturalist, Explorer, and Cinematographer. My compañero Loganapithicus and I travel the world in search of unique ecosystems to explore and document cinéma-vérité style. Our expeditions usually take place in an area of five square miles or less within a duration of 7-21 days and we focus on the entire ecosystem plants, animals, geology, weather, and more. We do not specifically seek out, bait, or wait for species, we film what we encounter as we explore the ecosystem on foot.
The purpose of our expeditions is to help in homo sapien's ceaseless quest for knowledge by documenting the ecosystems as they are forever changing with plant Earth as they have for billions of years. Our ecosystem videos can be viewed FREE by anyone and used for nonprofit educational instruction and testing purposes as well as scientific study of the ecosystems. Therefore we have left out narrations and used music in the background when no natural sound is available, ultimately leaving the videos for self interpretation, individual discovery, and for professors to explain or show as examples in a classroom setting.
We are unable to film every species in the selected ecosystems, as it is impossible to get everything in such a short time frame, one could spend an entire lifetime studying an ecosystem of planet Earth and still never see it all. No plant or animal species were harmed during our expeditions, all species are filmed in their natural habitat and are not coerced or paid for any performances. This is Mother Nature's movie if you have script questions please direct them towards her.

The Black Canyon Wilderness of Oregon is a wilderness area in the Ochoco National Forest. It drainage basin of the South Fork of the John Day River. It lies in Grant and Wheeler counties of Oregon. The nearest city is Dayville, in Grant County. It was established in 1984 and encompasses 13,400 acres (5,423 ha).
The elevation ranges from 2,850 to 6,483 feet (869 to 1,976 m). There are about seventeen miles of developed trail; eighty percent of the wilderness has a grade exceeding thirty percent, typically steep canyons and sharp ridges. Three sides of the canyon reach elevations to 6,000 feet (1,829 m), while waters in the gorge have downcut through basalt lava, emptying into the South Fork of the John Day River at 2,800 feet (853 m).
The Ochoco National Forest is located in Central Oregon in the United States, north and east of the City of Prineville, location of the National Forest Headquarters. It encompasses 850,000 acres (3,440 km2) of rimrock, canyons, geologic oddities, dense pine forests, and high desert terrain, as well as the headwaters of the North Fork of the Crooked River. A 1993 Forest Service study estimated that the extent of old growth in the Forest was 95,000 acres (38,000 ha).
In descending order of forestland area, it occupies lands within Crook, Harney, Wheeler, and Grant counties. The national forest also administers the Crooked River National Grassland, which is in Jefferson County.
An aquatic animal is an animal, either vertebrate or invertebrate, which lives in water for most or all of its life. Some examples of invertebrates are coelenterates. This phylum consists of jellyfish, anemones, corals, and hydras. Another type of invertebrate aquatic animal is the annelids which are segmented worms. There are three different classes they are polychaetes, oligochaetes, and hirudinea. It may breathe air or extract its oxygen from that dissolved in water through specialised organs called gills, or directly through its skin. Natural environments and the animals that live in them can be categorized as aquatic (water) or terrestrial (land). Animals that move readily from water to land and vice versa are referred to as amphibians. When animals live in water, they have special adaptations to help them survive in an aquatic habitat. The more time the animal spends in the water the quicker they adapt to their new habitat. There are numerous ways that an aquatic animal can adapt to their habitat.
The term aquatic can in theory be applied to animals that live in either freshwater (freshwater animals) or saltwater (seawater animals). However, the adjective marine is most commonly used for animals that live in saltwater, i.e. in oceans, seas, etc. Invasive aquatic animals require a water habitat, but do not necessarily have to live entirely in water.
Aquatic animals (especially freshwater animals) are often of special concern to conservationists because of the fragility of their environments. Aquatic animals are subject to pressure from overfishing, destructive fishing, marine pollution and climate change.
An aquatic ecosystem is an ecosystem in a body of water. Communities of organisms that are dependent on each other and on their environment live in aquatic ecosystems. The two main types of aquatic ecosystems are marine ecosystems and freshwater ecosystems.
Marine ecosystems cover approximately 71% of the Earth's surface and contain approximately 97% of the planet's water. They generate 32% of the world's net primary production. They are distinguished from freshwater ecosystems by the presence of dissolved compounds, especially salts, in the water. Approximately 85% of the dissolved materials in seawater are sodium and chlorine. Seawater has an average salinity of 35 parts per thousand (ppt) of water. Actual salinity varies among different marine ecosystems.
Marine ecosystems can be divided into many zones depending upon water depth and shoreline features. The oceanic zone is the vast open part of the ocean where animals such as whales, sharks, and tuna live. The benthic zone consists of substrates below water where many invertebrates live. The intertidal zone is the area between high and low tides; in this figure it is termed the littoral zone. Other near-shore (neritic) zones can include estuaries, salt marshes, coral reefs and mangrove swamps. In the deep water, hydrothermal vents may occur where chemosynthetic sulfur bacteria form the base of the food web.
Classes of organisms found in marine ecosystems include brown algae, dinoflagellates, corals, cephalopods, echinoderms, and sharks. Fishes caught in marine ecosystems are the biggest source of commercial foods obtained from wild populations.
Environmental problems concerning marine ecosystems include unsustainable exploitation of marine resources (for example overfishing of certain species), marine pollution, climate change, and building on coastal areas.
Snail is a common name that is applied most often to land snails, terrestrial pulmonate gastropod mollusks. However, the common name "snail" is also applied to most of the members of the molluscan class Gastropoda that have a coiled shell that is large enough for the animal to retract completely into. When the word "snail" is used in this most general sense, it includes not just land snails but also thousands of species of sea snails and freshwater snails. Occasionally a few other mollusks that are not actually gastropods, such as the Monoplacophora, which superficially resemble small limpets, may also informally be referred to as "snails".
Snail-like animals that naturally lack a shell, or have only an internal shell, are usually called slugs, and land snails that have only a very small shell (that they cannot retract into) are often called semislugs.
