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 narations 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.

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.
