Tag: Lined Butterflyfish (Chaetodon Lineolatus)

The Lined Butterflyfish (Chaetodon Lineolatus) is one of the largest members of the Butterflyfish family.

Reaching a length or around 30cm, this is a common species in local waters, although never found in significant numbers.

Usually found singularly or in pairs, this species is easily identified by its comparatively large size and distinctive colouration. The body is generally silvery/grey with thin black vertical bars joining a broader black bar at the rear.

All of the black vertical bars are around three quarter length, therefore the belly is generally unmarked.

The dorsal, pelvic and anal fins are all yellow and there is another yellow mark just forward of the thick black bar.

The main distinguishing feature is the white spot on the nape, surrounded by a wide black bar running vertically down the head.

It is this feature which distinguishes the species from the similar (though not locally occuring) Spot-Nape Butterflyfish (Chaetodon Oxycephalus).

The Lined Butterflyfish feeds on a diet consisting mainly of algae, coral polyps and small invertibrates.
