Лев (Panthera leo) — крупный представитель семейства кошачьих рода Panthera, обитающий в странах Африки к югу от Сахары и Индии.

У него ярко выражен половой диморфизм: взрослые самцы крупнее самок и имеют густую гриву. Это социальный вид, образующий группы, называемые прайдами. Львиный прайд состоит из нескольких взрослых самцов, родственных самок и детёнышей. Группы львиц обычно охотятся вместе, охотясь в основном на средних и крупных копытных.

The mail or post is a system for physically transporting documents and other small packages; or, the postcards, letters, and parcels themselves. A postal service can be private or public, though many governments place restrictions on private systems. Since the mid-19th century national postal systems have generally been established as government monopolies with a fee on the article prepaid. Proof of payment is often in the form of adhesive postage stamps, but postage meters are also used for bulk mailing. Modern private postal systems are typically distinguished from national postal agencies by the names "courier" or "delivery service". Postal authorities often have functions other than transporting letters. In some countries, a postal, telegraph and telephone (PTT) service oversees the postal system, in addition to telephone and telegraph systems. Some countries' postal systems allow for savings accounts and handle applications for passports.
