The beautiful and diverse butterflyfish...

Family Chaetodontidae, 'Butterflyfish'

Butterflyfish are medium sized fish that are extremely laterally compressed; that is, they have the shape of plate. They are usually dominated by black and yellow colours, but there are many variations. Butterflyfish are usually found in pairs.

This is my favourite group of fish! There are many species to identify, but all are distinct and relatively easy to ID.  

Forcipiger flavissimus, Long-nosed Butterflyfish (Aitutaki Fiji).

Chaetodon citrinellusSpeckled Butterflyfish (Aitutaki Fiji).

Chaetodon xanthocephalus, 'Yellow-headed Butterflyfish' (Alphonsa, Seychelles). 

Chaetodon octofasciatus, 'Eightband Butterflyfish' (Misool, Indonesia).

Chaetodon lunulatus, 'Oval/Pacific Redfin Butterflyfish', (Miyako Island, Japan).

Chaetodon reticulatus, 'Reticulated Butterflyfish, (Niue).

Chaetodon bennetti, 'Eclipse/Blue-lashed Butterflyfish' (Pink Beach, Komodo, Indonesia).

Thinking of travelling again after everything settles down? The first expedition I am booked to work on after the virus is the Great Barrier Reef in Australia with Coral Expeditions. Meanwhile, here is a shortened version of one of my lectures in a warmer part of the world.
