Aphanius, commonly referred to as Mediterranean killifish, is a genus of the order Cyprinodontiformes in the family Aphaniidae. They are found in fresh and brackish waters in the coastal plains of the Mediterranean region.

Taxonomy and systematics

[edit]

There were formerly 39 recognized species in this genus. However, the family Aphaniidae was split in 2020, and species were reallocated to eight monophyletic genera. Several species were reallocated; to five resurrected genera (Anatolichthys, Aphaniops, Kosswigichthys, Paraphanius, and Tellia) and two new genera Esmaeilius and Apricaphanius.[1]

Species

[edit]

Following the split, there are two valid species:[1]

Fossil record

[edit]

Fossils of extinct species, including A. crassicaudatus and A. yerevanicus, are known as far back as the Early Miocene of the Mediterranean and Caucasus regions.[3] are Fossils of Aphanius are found in strata of the Pleistocene of Italy (age range: from 11.608 to 5.332 million years ago.).[4]
