The Nile crocodile is NOT the largest crocodile species - the saltwater crocodile holds that title, reaching up to 7 meters and 1,000 kg, while Nile crocodiles max out around 6 meters and 750 kg. The other statements are true: snakes can regurgitate prey (though rarely voluntarily), whale sharks and basking sharks feed on plankton, and lions and tigers can produce hybrid offspring called ligers or tiglons.
