Notes: USVI fauna = combined fauna of St. John-Thomas and St. Croix, with exotic and primarily freshwater species excluded. Some genera and families have a deep member in one site but not the other, which affects USVI totals for deep and shallow genera and families. Shallow fishes: species exclusively or commonly found shallower than 40 m. Deep fishes: species exclusively or largely found deeper than 40 m (see methods for further details).
