Devil Scorpionfish
Scorpaenopsis diabolus
Devil Scorpionfish (Scorpaenopsis diabolus) is a venomous ambush predator of shallow Indo-Pacific reefs and rubble, famously cryptic and hard to spot. It rests motionless on the bottom and strikes small fish and crustaceans at close range.
Diamondfish
Monodactylus argenteus
Diamondfish (Monodactylus argenteus) is a laterally compressed silver schooling fish found in coastal estuaries, mangroves, and lower freshwater reaches. It is hardy and often kept in brackish aquaria; in the wild it feeds on small invertebrates and algae.
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.
Dollar Sunfish
Lepomis marginatus
Dollar Sunfish (Lepomis marginatus) is a small southeastern North American sunfish that inhabits warm, vegetated waters. It is more often caught incidentally than targeted, but it will take tiny baits and lures near cover.
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 Flathead
Platycephalus fuscus
Dusky Flathead (Platycephalus fuscus) is a large ambush predator of eastern Australian estuaries and inshore coastal waters. It lies buried in sand or mud, striking baitfish and prawns with a broad, camouflaged head and venomous dorsal spines.
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.
