New killifish species discovered in Brazilian Amazon

Researchers have identified a new species of killifish, named Laimosemion laranja, in the Rio Cajari drainage of Amapá, Brazil. The small freshwater fish, measuring less than three centimeters, is characterized by bright orange spots and chevron patterns on the males' bodies.

Scientists from institutions including the Universidade Federal do Rio Grande do Norte and the University of West Florida warn that the species may already be endangered. The fish was found in a limited number of forest pools that are currently threatened by human activity, prompting calls for urgent conservation efforts.
