Goby Lake that the diversity of species in the lake is greatly reduced from the nearby lagoon. The golden jellyfish "Mastigias" cf. "papua nakamurai" and possibly other species in the lake have evolved to be substantially different from their close relatives living in the nearby lagoons. The lake is rich with several species of fish, including goby, giving to lake its name. The deepest - north-eastern - part of Goby Lake is stratified into two layers, an oxygenated upper layer (mixolimnion) and a lower anoxic layer (monimolimnion). The oxygen concentration in the lake declines from about 6 mg/l at the surface to
Sphinx blenny Sphinx blenny The Sphinx blenny ("Aidablennius sphynx") is a species of combtooth blenny, and the only species in the genus "Aidablennius". It was described by Achille Valenciennes in 1836, originally under the genus "Blennius", and was later reassigned under ""Aidablennius"" by Gilbert Percy Whitley in 1947. It is a subtropical blenny known from Morocco, in the eastern Atlantic Ocean, and also from the Mediterranean and Black Seas. Sphinx blennies inhabit shallow, rocky waters in the littoral zone, with sunlight exposure. They feed primarily on benthic algae, weeds and invertebrates. Sphinx blennies can measure up to long in total length. In
