Teleost

Ang mga Teleost o Teleostei ( /ˌtɛliˈɒstiaɪ/; Greek teleios "kumpleto" + osteon "buto") /ˈtɛliɒsts,_ˈtiːliʔ/),^[4] ay ang pinakamalaking Impraklase sa klaseng Actinopterygii na mga isdang may palikpik na ray^[a] na naglalaman ng 96% ng lahat ng mga umiiiral na espesye ng isda. Ang mga teleost ay inaayos sa 40 na orden at 448 pamilya. Ang higit sa 26,000 espesye nito ay inilarawan ng mga biologo. Ang mga teleost ay kinabibilangan mula sa mgagiant oarfish na may sukat na 7.6 m (25 ft) at ocean sunfish na tumitimbang na 2 t (2.0 long ton; 2.2 short ton) hanggang sa maliliit na anglerfish Photocorynus spiniceps na 6.2 mm (0.24 in) ang haba. Hindi lamang ang may hugis na torpedong isda ang kasapi nito kundi pati rin ang mga patag na bertikal o horisontal na maaaring mga mahabang silindro ay mga espesyalisadong hugis gaya ng mga anglerfish at seahorse.
