The Actinopterygii /ˌaktɨnˌɔptəˈrɪdʒe.ai/, or ray-luggit fish, constitute a class or subclass o the bany fish.

The ray-luggit fish is sae cried acause thay hae lepidotrichia or "lug rays", thair lugs bein skin wabs uphaudit bi bany or horny pikes ("rays"). This is contrar tae the pluffie, lappit lugs that characterises the class Sarcopterygii whilk, housomeiver, haes lepidotrichia an aa. Thir actinopterygian lug rays steiks directly ontae the proximal or basal skeletal elements, the radials, whilk represents the link or connection atween thir lugs an the internal skelet (e.g., pelvic an pectoral girdles).

In numerical terms, actinopterygians is the dominant vertebrate class, comprisin naur 99% o the ower 30,000 fish species (Davis, Brian 2010). Thay are ubiquitous ootthrou freshwatter an marine environments frae the deep sea til the heichest muntain burns. Extant species can range in size frae Paedocypris, at 8 mm (0.3 in), tae the massive ocean sunfish, at 2,300 kg (5,070 lb), an the lang-bodied oarfish, at 11 m (36 ft).
