These horses can cost anywhere from $10,000 to $100,000 or more, with elite bloodlines fetching even higher prices (the most expensive one ever sold cost a mind-blowing $70 million). Known for ...
Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million in total. Animals range in size from 8.5 millionths of a metre to 33.6 metres (110 ft) long and have complex interactions with each other and their environments, forming intricate food webs .
The green discus is found in blackwater habitats with a high temperature of 27–30 °C (81–86 °F) and low pH of 4.8–5.9. [4] Although also known from whitewater , its preference for lentic habitats such as floodplains means that the water contain little suspended material (unlike main sections of whitewater rivers).
Fishes of the World is a standard reference for the systematics of fishes.It was first written in 1976 by the American ichthyologist Joseph S. Nelson (1937–2011). Now in its fifth edition (2016), the work is a comprehensive overview of the diversity and classification of the 30,000-plus fish species known to science.
