Butterflyfish, Family Chaetodontidae (lauhau in Hawiian)
IUCN Red List is provided for each gallery. It provides a fairly comprehensive explanation of their range, feeding habits, ecological threats and diversity. Apparently, none of the butterflyfish captured here are considered a species at risk, but in parts of the world where coral loss has been significant, their numbers have visibly dropped. With severe bleaching events hitting Maui for two years in a row (2014/15), the population of butterflyfish will be watched closely.
