Codlets are a family, Bregmacerotidae, of cod-like fishes, containing the single genus Bregmaceros found in tropical and subtropical waters throughout the world. They are very small fishes and even the largest, B. lanceolatus, reaches only 11.5 cm (4.5 in) in length.
Their scientific name is from Greekbregma meaning the top of the head, and keras meaning "horn"; this refers to their occipital ray (a spine emerging from the top of the head).
A potential extinct relative, Bregmacerina, is known from the Early Miocene of Russia, where it inhabited the Paratethys. It shares close similarities to Bregmaceros in the reduction of the first dorsal fin, but differs in other aspects. It remains uncertain whether it is an actual member of the Bregmacerotidae.[3]
