Open encyclopedia reference
Empetrichthys latos is a rare species of fish in the family Goodeidae, the splitfins. It is known by the common names Pahrump poolfish and Pahrump killifish, the former being more correct today. It is endemic to Nevada in the United States, where it was limited to the Pahrump Valley near the California border. It nearly became extinct due to habitat destruction and no longer occurs there. It is a federally listed endangered species of the United States. The Pahrump Poolfish is long-lived for a small-bodied fish, with ages up to 10 years for females and 7 years for males documented. The Pahrump Poolfish is sexually dimorphic; females being significantly larger. This is an important consideration for management as establishing populations with a balanced sex ratio is likely desired. This fish reaches a maximum length of about 7 cm (2.8 in). It has its dorsal and anal fins far back on its body and it lacks pelvic fins. The head is depressed in front and the mouth is wide. The jaws are unequal, the lower projecting farther than the upper.
