The Chinese paddlefish was officially declared extinct in 2022, with an estimated time of extinction to be by 2005, and no later than 2010, although it had become functionally extinct by 1993. [ 1 ] [ 4 ] The main cause of its extinction was the construction of the Gezhouba and Three Gorges dams , causing population fragmentation and blocking ...
The primary reasons for the decline of the now-extinct Chinese paddlefish are similar to those of American paddlefish, which include overfishing, the construction of dams, and destruction of habitat. [37] The last confirmed sighting of a live Chinese paddlefish was from the Yangtze River on January 24, 2003. [56]
American paddlefish commonly reach 5 ft (1.5 m) or more in length and can weigh more than 60 lb (27 kg). The largest American paddlefish on record was caught in 1916 in Okoboji Lake, Iowa. [17] The fish was taken with a spear, and measured 7 ft 1 in (2.16 m) long and 45.5 in (1.16 m) in the girth. [17]

The O‘ahu ‘ō‘ō (Moho apicalis) is among dozens of bird species that became extinct after the human settlement of Hawaii. This is a list of Hawaiian animal species extinct in the Holocene that covers extinctions from the Holocene epoch, a geologic epoch that began about 11,650 years before present (about 9700 BCE ) [ a ] and continues to ...
A herd of axis deer in Maui. Hawaii is the most isolated major land mass in the world and that isolation has led to very high rates of endemism.Uniquely adapted endemic species are often sensitive to competition from invasive species and Hawaii has had numerous extinctions (List of extinct animals of the Hawaiian Islands).
Located about 2,300 miles (3,680 km) from the nearest continental shore, the Hawaiian Islands are the most isolated group of islands on the planet. The plant and animal life of the Hawaiian archipelago is the result of early, very infrequent colonizations of arriving species and the slow evolution of those species—in isolation from the rest of the world's flora and fauna—over a period of ...
