Drepane is a genus of marine and brackish water ray-finned fishes, known commonly as the sicklefishes.

[2] These fish occur in the Indian and western Pacific Oceans, and in the eastern Atlantic near Africa.

[2] The 5th edition of Fishes of the World classifies the Drepaneidae within the order Moroniformes alongside the Moronidae and Ephippidae.

[5] However, other authorities have found that the Moronidae is not closely related to the other two families and classify the Drepaneidae and the Ephippidae in the order Ephippiformes.

They have a highly protractile mouth, the pectoral fins are longer than the head and are shape like sickles.
