The Indian peafowl is known to live for up to 23 years in captivity. However, it is estimated to live for only about 15 years in the wild. [63] Large predators such as tiger, leopard, hyena, dhole, and golden jackal, can ambush an adult Indian peafowl. An adult peafowl is difficult to capture since it can usually escape these ground predators ...

It was thought that the sharks form a polyphyletic group: some sharks are more closely related to rays than they are to some other sharks, [21] but current molecular studies support monophyly of both groups of sharks and batoids. [22] [23] The clade Selachimorpha is divided into the superorders Galea (or Galeomorphii), and Squalea (or ...
Most species live on the sea floor, in a variety of geographical regions – mainly in coastal waters, although some live in deep waters to at least 3,000 metres (9,800 ft). Most batoids have a cosmopolitan distribution , preferring tropical and subtropical marine environments, although there are temperate and cold-water species.
