An aquatic animal is an animal, either vertebrate or invertebrate, which lives in the water for most or all of its lifetime. Many insects such as mosquitoes, mayflies, dragonflies and caddisflies have aquatic larvae, with winged adults. Aquatic animals may breathe air or extract oxygen that dissolved in water through specialised organs called gills, or directly through the skin. Natural environments and the animals that live in them can be categorized as aquatic (water) or terrestrial (land).
where do animals and plants get the oxygen from in the aquatic environment

Those who hold for the importance of apostolic succession via episcopal laying on of hands appeal to the New Testament, which, they say, implies a personal apostolic succession (from Paul to Timothy and Titus, for example). They appeal as well to other documents of the early Church, especially the Epistle of Clement. In this context, Clement explicitly states that the apostles appointed bishops as successors and directed that these bishops should in turn appoint their own successors; given this, such leaders of the Church were not to be removed without cause and not in this way. Further, proponents of the necessity of the personal apostolic succession of bishops within the Church point to the universal practice of the undivided early Church (up to AD 431), before being divided into the Church of the East, Oriental Orthodoxy, the Eastern Orthodox Church and the Roman Catholic Church. Christians of the Roman Catholic, Orthodox, Old Catholic, Anglican, Moravian, and Scandinavian Lutheran traditions maintain that 'a bishop cannot have regular or valid orders unless he has been consecrated in this apostolic succession.' Each of these groups does not necessarily consider consecration of the other groups as valid.

The great Angel Falls (Spanish: Salto Angel; Pemon language: Kerepakupai Meru meaning 'waterfall of the deepest place', or Parakupa Vena, meaning 'the fall from the highest point') is a waterfall in Venezuela. It is the world's highest uninterrupted waterfall, with a height of 979 metres (3,211 feet) and a plunge of 807 metres (2,368 feet). The waterfall drops over the edge of the Auyan-tepui mountain in the Canaima National Park (Spanish: Parque Nacional Canaima), a UNESCO World Heritage site in the Gran Sabana region of Bolivar State. The height figure 979 metres (3,211 feet) mostly consists of the main plunge but also includes about 400 metres (0.25 mi) of sloped cascade and rapids below the drop and a 30-metre (98 ft) high plunge downstream of the talus rapids.
