The African bush elephant (foreground), Earth's largest extant land animal, and the Masai ostrich (background), one of Earth's largest extant birds. In zoology, megafauna (from Greek μέγας megas "large" and Neo-Latin fauna "animal life") are large animals. The precise definition of the term varies widely, though a common threshold is ...
African forest elephant (Loxodonta cyclotis) The African forest elephant is the smallest species of elephants. It is native to West Africa and the Congo Basin. It is one of two species of African elephants, the other being the African bush elephant. [13] Its trunk has two finger-like processes and contains about 40–60,000 muscles. [14]
In zoology, megafauna (from Greek μέγας megas "large" and Neo-Latin fauna "animal life") are large animals. The most common thresholds to be a megafauna are weighing over 46 kilograms (100 lb) [ 2 ] [ 3 ] [ 4 ] (i.e., having a mass comparable to or larger than a human ) or weighing over a tonne , 1,000 kilograms (2,205 lb) [ 2 ] [ 5 ] [ 6 ...
Elephants average 3–4 hours of sleep per day. [89] Both males and family groups typically move no more than 20 km (12 mi) a day, but distances as far as 180 km (112 mi) have been recorded in the Etosha region of Namibia. [90] Elephants go on seasonal migrations in response to changes in environmental conditions. [91]
An African bush elephant (Loxodonta africana), is an example of charismatic megafauna.. Charismatic megafauna are animal species that are large—in the category that they represent [1] —with symbolic value or widespread popular appeal, and are often used by environmental activists to gain public support for environmentalist goals.

From large to small, the St Johns River off Florida's coast is home to the large manatees and dolphins to small fish, crabs and shrimp. From megafauna to anchovies, the St. Johns River is swimming ...
Life restoration of Thylacoleo carnifex (also known as the marsupial lion) This theory is based on evidence of megafauna surviving until 40,000 years ago, a full 30,000 years after homo sapiens first landed in Australia, and thus that the two groups coexisted for a long time. Evidence of these animals existing at that time come from fossil ...
These features allowed mammoths to live an expansive life because of the availability of grasses and trees. [29] Today, nine of the 50 species persist. The Americas saw the worst decline in megaherbivores, with all 27 species going extinct. [3] The Quaternary Extinction Event is an event where many species of megafauna (particularly mammals ...
