Ballina Angelfish, Chaetodontoplus ballinae (Whitley, 1959)
Introduction
The Ballina Angelfish is a protected species that is only known from northern coastal New South Wales and Balls Pyramid, near Lord Howe Island, New South Wales.
Identification
The Ballina Angelfish can be recognised by its distinctive colouration. It is pearly grey to whitish with a broad region of black covering much of the back and pectoral fin base. There are black areas through the mouth and eye. The pectoral and caudal fins are yellow.
Habitat
It occurs in subtropical marine waters at depths between 15 m and 120 m.
Distribution
The Ballina Angelfish is only known from coastal northern New South Wales and Balls Pyramid, near Lord Howe Island, New South Wales.
The species was described in 1959 by G.P. Whitley, Curator of the Australian Museum Fish Department for 42 years. He described the species based on a single specimen caught off Ballina, northern New South Wales.
It wasn't until 1978 that another specimen was collected by K. Graham (ex. NSW Fisheries, now AM Research Associate), working aboard the FRV Kapala. This fish was trawled from a depth of around 120 m off Evans Head (AMS I.22515-001)
Three specimens were obtained in 1994 by P. Parker at a depth of 25 m near Ball's Pyramid (AMS I.34842-001).
The NORFANZ expedition in 2003 trawled three specimens at a depth of 90 m, near Ball's Pyramid, south-east of Lord Howe Island. K. Graham and K. Parkinson (NORFANZ voyage participants) registered one of these specimens into the Australian Museum Fish Collection (AMS I.42727-004).
