The nene goose is Hawaii's state bird and, up until recently, the humuhumunukunukuapuaa was its state fish.

The nene (Branta sandvicensis) is a large grey, black, and white goose so similar in appearance to a Canada goose that it is believed that the nene evolved from migrating Canada blown off course.
Nenes are 22-26 inches long with a black head and nape and yellow cheeks. Their buffy-colored necks are striped, leading to a heavily barred gray-brown back. Nenes' bills and feet are black.

Nenes feed on vegetation in scrubland, grasslands, golf courses, and open lowlands.
Like so many of Hawaii's endemic birds, the nene is extremely endangered. It was nearly extinct in the wild by 1951. Captive-bred birds have been reintroduced since 1957 into Haleakala Crater on Maui and its former ranges on The Big Island and Kauai. But there are still fewer than 300 wild nenes.

The humuhumunukunukuapuaa (pronounced HOO-moo-HOO-moo-NOO-koo-NOO-koo-AH-poo-AH-ah) -- aka Hawaiian trigger fish -- is a stubby-nosed, brightly striped, and slightly aggressive fish whose name is nearly longer than its body.

Up until recently, everyone thought the humuhumunukunukuapuaa was Hawaii's state fish. As it turns out, it had been quietly dethroned.

In 1984, the state Legislature asked the University of Hawaii and the Waikiki Aquarium to survey the public to come up with a candidate for another state fish. But the polling method was questioned, and lawmakers limited the designation to five years. So the humuhumunukunukuapuaa is no longer the official state fish, but efforts are under way to reinstate it.
