Crimson-tipped Flathead-gudgeon, Crimson-tipped Gudgeon, Flat-head Gudgeon
The Crimsontip Gudgeon can be distinguished from other freshwater gudgeons by its shovel-like snout.
The Crimsontip Gudgeon is a medium-sized gudgeon with a long 'shovel-like' snout. Its colour is variable but it is often mottled brown with red spots on the sides and median fins.
In his 2011 paper (see below) Research Associate, Dr Anthony Gill stated that "butis (buti-singular) is a decorative, circular design woven, embroidered or printed on cloth, and is particularly common in sari fabric."
Lower reaches of streams and estuaries usually on muddy bottoms.
It occurs widely throughout the Indo-west Pacific. In Australia it is known from north-western Western Australia, around the tropical north and south to northern New South Wales.
