Sashatherina giganteus is a freshwater fish from the Old World earfish family(Atherinidae) that is endemic to Lake Lakamorain the Indonesian province of Papua in New Guinea .
Features and occurrences
Sashatherina giganteus is very slender and clearly surpasses other Old World earfish with a body length of at least 18 cm. The species is covered with very many small scales . Thereby 60 scales are counted in the middle long side and up to 17 horizontal rows of scales. It is also unusual that all of the scales have irregularly jagged edges. The lower jaw is very pronounced and extends beyond the front edge of the intermaxillary bone ( premaxillary ). Compared to other species, the shoulder girdle is shaped differently. The eyes are comparatively small.
This big, hard-headed one occurs only in the few square kilometers large lake Lakamora fifty kilometers east of the port city of Kaimana near the Triton Bay in southern West Papua.
Systematics
Sashatherina giganteus is the only member of the genus Sashatherina . On the basis of osteological characteristics, it is closely related to the hard-headed genus Craterocephalus , which occurs in fresh, brackish or salt water in Australia, New Guinea and East Timor.
