Doctorfish
Acanthurus chirurgus
Doctorfish (Acanthurus chirurgus) is a surgeonfish of warm western Atlantic reefs and seagrass edges. It grazes on algae and detritus and can slash with the sharp spine at the base of its tail.
Dot-and-dash Goatfish
Parupeneus barberinus
Dot-and-dash Goatfish (Parupeneus barberinus) is a reef-associated goatfish of tropical Indo-Pacific waters, often over sand and rubble near coral reefs. It uses chin barbels to probe the bottom for small invertebrates and is generally a modest food fish where taken.
Doublebar Rabbitfish
Siganus virgatus
Doublebar Rabbitfish (Siganus virgatus) is a venomous rabbitfish of Indo-West Pacific reefs and lagoons, often feeding in pairs or small schools. It grazes algae and seagrass on shallow coral flats and reef edges; the spines can inflict a painful sting.
Dusky Batfish
Platax pinnatus
Dusky Batfish (*Platax pinnatus*) is a reef-associated batfish of the Indo-Pacific, usually seen alone or in small groups. Juveniles mimic drifting leaves with bold black-and-yellow striping; adults are taller-bodied and dusky gray to brown.
Dusky Butterflyfish
Chaetodon flavirostris
The Dusky Butterflyfish is a reef-associated butterflyfish of the Indo-Pacific, recognized by its dark body and yellow snout. It feeds mainly on coral polyps, small invertebrates, and benthic algae, and is generally not a targeted angling species.
Dusky Damselfish
Stegastes adustus
Dusky Damselfish (Stegastes adustus) is a reef-associated damselfish of the western Atlantic, usually living close to coral and rock structure. It is small, territorial, and often seen in shallow tropical reefs where it tends and defends a patch of algae.
Dusky Gregory
Stegastes nigricans
Dusky Gregory is a territorial damselfish of shallow coral reefs and lagoon margins, often defending a small turf-algae garden. It is small, bold, and usually seen close to branching corals or rubble in clear tropical water.
Dusky Grouper
Epinephelus marginatus
Dusky Grouper (Epinephelus marginatus) is a large, slow-growing reef grouper found along rocky coasts and reefs in the eastern Atlantic and Mediterranean. It is a wary ambush predator and a prized but often protected recreational species in many areas.
Dusky Morwong
Dactylophora nigricans
Dusky Morwong (Dactylophora nigricans) is a large, kelp-reef-associated fish of temperate southern Australia and New Zealand. It is commonly taken by line and thought to feed mainly on algae and small benthic invertebrates.
Dusky Spinefoot
Siganus luridus
Dusky Spinefoot (Siganus luridus) is a venomous rabbitfish of the eastern Mediterranean and Red Sea that grazes algae on rocky reefs and seagrass beds. It is an important food fish in parts of its range, but the dorsal and anal spines can inflict painful wounds.
Dusky Surgeonfish
Acanthurus nigrofuscus
Dusky Surgeonfish (Acanthurus nigrofuscus) is a small reef-dwelling surgeonfish of tropical Indo-Pacific and adjacent waters, now recorded widely in the Red Sea and many oceanic islands. It grazes on algae over shallow coral and rocky reefs and carries a sharp tail spine; it is not a common target fish.
Dussumier's Rockskipper
Istiblennius dussumieri
Dussumier's Rockskipper (Istiblennius dussumieri) is a small tropical blenny that lives on wave-washed rocky shores. It clings to rocks in the intertidal zone and is usually of little angling interest.
