Asiatic lion known as "Indian lion" and "Persian lion". Following Meyer's first description of an Asiatic lion skin from Persia, other naturalists and zoologists also described lion specimens from other parts of Asia that used to be considered synonyms of "P. l. persica": In 2017, the Asiatic lion was subsumed to "P. l. leo" due to close morphological and molecular genetic similarities with Barbary lion specimens. Fossil remains of "Panthera spelaea" excavated in the Cromer Stage indicate that it represented a genetically isolated and highly distinct lineage. Fossil lion remains were found in Pleistocene deposits in West Bengal. A fossil carnassial excavated
Apex predator tethered cormorants have been used to catch fish. Ecotourism sometimes relies on apex predators to attract business. Tour operators may in consequence decide to intervene in ecosystems, for example by providing food to attract predators to areas that can conveniently be visited. This in turn can have effects on predator population and therefore on the wider ecosystem. As a result, provisioning of species such as the tiger shark is controversial, but its effects are not well established by empirical evidence. Other affected apex predators include big cats and crocodiles. In some densely populated areas like the British Isles, all the
