Blackblotched Porcupinefish
Diodon liturosus
Blackblotched porcupinefish is a medium-large spiny puffer of tropical Indo-Pacific reefs, lagoons, and sheltered coastal waters. It inflates when threatened and carries potent tetrodotoxin in its tissues and organs.
Blackchin Tilapia
Sarotherodon melanotheron
Blackchin tilapia is an euryhaline African cichlid now established in many tropical and subtropical coastal waters and estuaries. It thrives in warm, low-salinity bays, lagoons, mangroves, canals, and brackish marshes, often in turbid, vegetation-lined water.
Blackeye Goby
Rhinogobiops nicholsii
Blackeye Goby is a small marine goby common on rocky reefs, kelp forests, and sheltered coastal zones. It stays close to the bottom in shallow water and is often seen perched on substrate or in crevices.
Blackeye Thicklip
Hemigymnus melapterus
Blackeye Thicklip is a reef-associated wrasse found on tropical Indo-Pacific reefs. It forages in mixed algal and invertebrate prey along coral and rubble, and is more of a food/forage species than a common sport target.
Blackfin Barracuda
Sphyraena qenie
Blackfin barracuda is a large, streamlined predatory fish of Indo-Pacific reefs and offshore slopes. It is mostly a solitary ambush hunter, feeding on smaller fish and occasionally cephalopods, and is valued more as a game fish than a table fish.
Blacklip Butterflyfish
Chaetodon kleinii
Blacklip Butterflyfish (Chaetodon kleinii) is a reef-associated butterflyfish found across the Indo-Pacific, often around coral and rocky reefs, lagoons, and seaward slopes. It feeds on small benthic invertebrates, especially coral polyps, worms, and crustaceans.
Blacksaddle Goatfish
Parupeneus spilurus
A small Indo-Pacific goatfish associated with reef and lagoon habitats, where it forages over sand and rubble. Like other goatfishes, it uses chin barbels to probe the bottom for buried prey.
Blacksaddle Toby
Canthigaster valentini
The blacksaddle toby is a small, venomless pufferfish found on Indo-Pacific coral reefs and lagoons. It commonly occurs in shallow tropical waters where it grazes on benthic invertebrates and algae, and it can inflate when threatened.
Blackspot Sergeant
Abudefduf sordidus
Blackspot Sergeant is a reef-associated damselfish found in warm Indo-Pacific waters. It lives in shallow coastal reefs and surge channels, where it feeds mainly on algae and small benthic invertebrates.
Blackspot Snapper
Lutjanus fulviflamma
Blackspot Snapper is a reef-associated lutjanid found across the Indo-West Pacific, especially around coastal reefs, lagoons, and deeper reef slopes. It is a predatory snapper that feeds mainly on fishes and crustaceans and is taken by anglers in tropical saltwater fisheries.
Blackspotted Puffer
Arothron nigropunctatus
A large Indo-Pacific reef puffer with a bluish to gray body covered in black spots and a beak-like mouth. It is common around coral and rocky reefs, where it grazes on hard-shelled invertebrates and algae.
Blackspotted Topminnow
Fundulus olivaceus
Blackspotted Topminnow is a small North American killifish associated with slow, warm, vegetated freshwater. It forages near the surface and among plants, taking tiny aquatic insects and other small invertebrates.
