Water footprint of live animal at end of life time (m3/ton)
A major way animals have evolved to osmoregulate is by controlling the amount of water lost through the .
There are earlier publications on the water use behind animal production (Steinfeld and others ; Galloway and others ; Pimentel and others ; Chapagain and Hoekstra , ; De Fraiture and others ; Peden and others ; Van Breugel and others ; Renault and Wallender ), but a detailed comprehensive global assessment was lacking. The objective of the current paper is to provide such an assessment by quantifying the water footprint of farm animals and of the various derived animal products per country and per animal production system. The period of analysis was 1996–2005. The water footprint of a product consists of three colour-coded components: the green, blue and grey water footprint (Hoekstra and Chapagain ). The blue water footprint refers to the volume of surface and groundwater consumed (that is evaporated after withdrawal) as a result of the production of the product; the green water footprint refers to the rainwater consumed. The grey water footprint refers to the volume of freshwater that is required to assimilate the load of pollutants based on existing ambient water quality standards. Water footprint calculations have been based on the recently established global water footprint standard (Hoekstra and others ), which was developed based on earlier water footprint studies (see for example, Chapagain and others ; Hoekstra and Chapagain ; Gerbens-Leenes and others ; Aldaya and others ).
Capybaras are . While they sometimes live solitarily, they are more commonly found in groups of around 10–20 individuals, with two to four adult males, four to seven adult females, and the remainder juveniles. Capybara groups can consist of as many as 50 or 100 individuals during the dry season when the animals gather around available water sources. Males establish social bonds, dominance, or general group consensus. They can make dog-like barks when threatened or when females are herding young.

Manatees are usually seen alone, in pairs, or in small groups of a half dozen or fewer animals. From above the water's surface, the animal's nose and nostrils are often the only thing visible. Manatees never leave the water but, like all marine mammals, they must breathe air at the surface. A resting manatee can remain submerged for up to 15 minutes, but while swimming, it must surface every three or four minutes.Manatees are large, slow-moving animals that frequent coastal waters and rivers. These attributes make them vulnerable to hunters seeking their hides, oil, and bones. Manatee numbers declined throughout the last century, mostly because of hunting pressure. Today, manatees are at-risk. Though protected by laws, they still face threats. The gentle beasts are often accidentally hit by motorboats in ever more crowded waters, and sometimes become entangled in fishing nets.About two-thirds of the Earth is covered with water. This is home for many of the Earth's creatures. Many different kinds of animals live in water. Most people are familiar with living in water. Other animals that live in water include: , , , , and even some and .Various species of water turtles are kept as pets in the United States. Most of those purchased by hobbyists originate from the southern and eastern regions of the U.S. By law, imported turtles of most species must be at least 4 inches long. The trade in exotic turtles has been increasing in recent years, especially in countries with poor animal protection laws and abundant turtle populations.
