The crane is a large, long-beaked bird that is found all over the world. There are 15 different species of crane found on Earth today, but despite their similar appearance, cranes are not related to other long-necked birds such as herons.
Cranes are found on every continent with the exceptions of the Antarctic and South America, where they are found inhabiting the temperate wetlands and swamps throughout the Northern and Southern Hemispheres.
Cranes are large sized birds that to grow to an average of 1 meter in height. Some species of crane however, such as the Red-Crowned crane of Eastern Asia, can grow to nearly 1.5 meters tall. Other crane species can be slightly smaller altho
Whale is the common name for a widely distributed and diverse group of fully aquatic placental marine mammals. They are an informal grouping within the infraorder Cetacea, usually excluding dolphins and porpoises. Whales, dolphins and porpoises belong to the order Cetartiodactyla with even-toed ungulates and their closest living relatives are the hippopotamuses, having diverged about 40 million years ago. The two parvorders of whales, baleen whales (Mysticeti) and toothed whales (Odontoceti), are thought to have split apart around 34 million years ago. The whales comprise eight extant families: Balaenopteridae (the rorquals), Balaenidae (right whales), Cetotheriidae (the pygmy right whale),

Bycatch is the most critical extinction threat facing marine megafauna in coastal seas, including the world's most endangered dolphins, porpoises, seals, dugongs, sharks, and marine turtles. These vulnerable species share coastal waters with small-scale fisheries that employ 99% of the world's 50 million fishers. An estimate of global dolphin and porpoise bycatch indicates that more than 300,000 individuals are killed each year, with about 98% resulting from entanglement in gillnets and about 2% in trawlers and other gear, such as long lines.
A global review of marine mammal consumption by humans concluded that targeted hunts of small cetaceans have generally been reduced and capture
