Bigeye Numbfish

The Bigeye Numbfish (Narcine oculifera) is a species in the genus Narcine.

Collared Sprite

The Collared Sprite, known scientifically as <em>Thainycteris aureocollaris</em>, is a bat belonging to the order Chiroptera. <em>Thainycteris aureocollaris</em> is distinguished by a golden or pale collar of fur around the neck region, which gives rise to the species epithet "aureocollaris" — meaning golden-collared in Latin. The species inhabits diverse terrestrial and aquatic ecosystems. Bats of this type are generally nocturnal, roosting during the day and emerging at night to forage on flying insects using echolocation. Detailed biological traits including typical lifespan, body length, and weight are poorly documented for this species in available literature. The Collared Sprite is currently assessed as Least Concern on the IUCN Red List, indicating that the global population is not currently considered to be at significant risk of decline.
