Introduction

The Dot-and-dash Goatfish can be recognised by a large black spot on the caudal peduncle. It is found in tropical marine waters.

Identification

The Dot-and-dash Goatfish has a pale whitish body with a dark stripe that extends from the mouth, through the eye and along the upper side of the fish. There is a large black spot on the caudal peduncle.

Habitat

The Dot-and-dash Goatfish inhabits lagoons and seaward reefs and is most commonly seen over large sandy and rubbly areas. It occurs in groups or as solitary individuals during the day. At night it is solitary, resting on the bottom. It can be found at depths of 1 m to 100 m.

Distribution

The Dot-and-dash Goatfish occurs in tropical marine waters of the Indo-Pacific region, from East Africa, north to Japan, throughout Micronesia, south to Australia and east to the Tuamoto Islands. In Australia it is known from the north-western coast of Western Australia, around the tropical north of the country, and south to central coast of New South Wales.

Feeding and diet

During the day the Dot-and-dash Goatfish forages in groups for benthic crustaceans and polychaete worms. It is commonly seen probing sandy or rubbly bottoms with its barbels, which are located under the chin. The barbels contain chemosensory organs. When not in use, the barbels are tucked under a portion of the gill covers.
