In 1797, French naturalist Bernard Germain de Lacépède established the genus Polyodon for paddlefish, [4] which today includes a single extant species, Polyodon spathula. Lacépède disagreed with Pierre Joseph Bonnaterre 's description in Tableau encyclopédique et méthodique (1788), which had suggested that paddlefish were a species of shark.
Location of Hawaii in the Pacific Ocean. 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 ...
[10] [11] [16] Although the American paddlefish is one of the largest freshwater fishes in North America, their recorded lengths and weights fell short in comparison to the larger Chinese paddlefish.

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 ...
Vulnerable (VU) species are considered to be facing a high risk of extinction in the wild. In September 2016, the International Union for Conservation of Nature (IUCN) listed 1245 vulnerable fish species. [1] Of all evaluated fish species, 8.1% are listed as vulnerable. The IUCN also lists eight fish subspecies as vulnerable.
The American paddlefish is the only species of paddlefish living after the extinction of the Chinese paddlefish, which was estimated to be extinct by 2005, and no later than by 2010. [6] Sturgeons are considered by IUCN to be the most critically endangered group of species in the world based on over 85% of sturgeon species being at risk of ...
