Teardrop Butterflyfish - Chaetodon unimaculatus

The Teardrop Butterflyfish, "Chaetodon unimaculatus", is a species of butterflyfish. In the Indian Ocean it is replaced by the Yellow Teardrop Butterflyfish, now considered to be a separate species but previously included in "C. unimaculatus" as a subspecies. In its subgenus "Lepidochaetodon" – sometimes considered a separate genus – it is only distantly related to species such as the Sunburst Butterflyfish and the Tahiti Butterflyfish.
