The duckbill pugolovka (Anatirostrum profundorum) is a species of gobiid fish endemic to the southern part of the Caspian Sea.

It is characterized by its special flattened and elongated head that resembles a duck's bill.

[3] It was initially found in 1904 at a depth of 294 metres (965 ft) (arguably 447 m (1,467 ft)).

Only recently more samples of this species have been collected from Iranian waters, where it mainly lives at 50–100 m (160–330 ft) depth.
