SPECIE NAME:Holocentrus rufus
COMMON NAME OF THE SPECIE: Longspine Squirrelfish
LOCATION: Western Atlantic Ocean, including the Caribbean Sea, Gulf of Mexico, Bahamas and areas along the southeastern United States and northern South America.
HABITAT: It is a reef-associated marine fish found around coral reefs, rocky structures, caves, crevices and reef overhangs. It usually shelters in protected reef structures during daylight and becomes more active after dark.
SIZE: Typical size: approximately 15–25 cm total length.
DIET: Longspine Squirrelfish is a carnivorous nocturnal predator. It becomes more active after sunset and searches around reef surfaces and crevices for small crustaceans and other small marine animals.
FACT: It belongs to the Holocentridae family. It is a true squirrelfish species, rather than merely a general group name. It is primarily active at night. During daylight, it often hides inside reef caves, holes and crevices. Its large eyes are adapted for low-light conditions. Its body generally has a reddish coloration with contrasting markings. The species has prominent spines on its fins, which can provide protection against predators. It has a relatively large head and eyes compared with many reef fishes. It uses reef structures as both shelter and feeding habitat. It feeds primarily on small animal prey rather than algae or plant material.

SPECIE NAME:Myripristis berndti
COMMON NAME OF THE SPECIE: Bigscale Soldierfish
LOCATION: Bigscale Soldierfish has a broad Indo-Pacific and Eastern Pacific distribution. It occurs from East Africa and southern Africa eastward across the Indian and Pacific Oceans, including areas around the Great Barrier Reef, Micronesia, Polynesia, Ryukyu Islands, Norfolk Island, Lord Howe Island, Clipperton, Cocos and Galápagos Islands. It is absent from the Red Sea.
HABITAT: It is a marine, reef-associated fish that commonly inhabits subtidal reef flats, channels, reef margins, caves, ledges and outer reef slopes. During daylight it generally hides in caves or underneath reef ledges and becomes more active at night. Its recorded depth range is approximately 0–159 m, although it is usually encountered much shallower, around 3–15 m.
SIZE: Common length: approximately 22 cm total length. Maximum recorded length: approximately 30 cm total length
DIET: Bigscale Soldierfish is primarily a planktivorous predator. It feeds mainly in the water column on small planktonic organisms, particularly crab larvae and other small crustaceans. Its feeding activity is strongly associated with nighttime, when the fish is commonly encountered outside its daytime shelter.
FACT: Bigscale Soldierfish belongs to the Holocentridae family, which includes soldierfish and squirrelfish.Its scientific name is Myripristis berndti. It can reach approximately 30 cm in total length.Its common recorded length is around 22 cm. Its scales have silvery-pink to pale-yellow centers with red edges, giving the fish a distinctive appearance. The outer portion of its spiny dorsal fin can be yellow to orange-yellow. The lower portions of several fins are red, while their leading edges can be white.

SPECIE NAME:Diploprion bifasciatum
COMMON NAME OF THE SPECIE: Barred Soapfish
LOCATION: Found in the Indo-West Pacific, from the Red Sea and East Africa eastward through the Indian Ocean and western Pacific, including areas around Indonesia, the Philippines, southern Japan, Papua New Guinea and northern Australia.
HABITAT: A marine reef-associated fish that lives around coral reefs, rocky reef areas, caves, crevices and sheltered reef structures. It is generally associated with relatively shallow reef environments but can occur at considerable depth.
SIZE: Common size: approximately 15–20 cm total length.
DIET: Barred Soapfish is a carnivorous predator that feeds on small animal prey. It can ambush small fishes and invertebrates around reef structures. Like other soapfishes, it possesses specialized skin mucus that can serve as a chemical defense against predators.
FACT: It belongs to the family Grammistidae, the soapfishes. Its scientific name is Diploprion bifasciatum. The species is commonly called Barred Soapfish. It has a distinctive body pattern with dark vertical bars or bands contrasting against a lighter background. The barred pattern helps distinguish it from many other reef-associated soapfishes.

SPECIE NAME:Lutjanus monostigma
COMMON NAME OF THE SPECIE: One-spot Snapper
LOCATION: The One-spot Snapper is distributed throughout the Indo-Pacific, from East Africa eastward to the Marquesas and Line Islands, north to the Ryukyu Islands and south to Australia.
HABITAT: It is a marine and reef-associated snapper that occurs from approximately 1–60 m depth. Adults are usually found around coral reefs, particularly near caves, large coral formations and wrecks that provide shelter. It may also tolerate brackish water in some areas.
SIZE: Common length: approximately 50 cm total length.
DIET: The One-spot Snapper is a carnivorous predator. Adults feed mainly on fishes and benthic crustaceans, especially crabs. Feeding occurs primarily at night, when the fish becomes more active around reef structures .
FACT: It belongs to the Lutjanidae family, commonly known as the snapper family. Its scientific name is Lutjanus monostigma. Its common name, One-spot Snapper, refers to its characteristic dark spot. The species generally has a whitish to pinkish body with dusky scale margins.

SPECIE NAME:Cephalopholis formosa
COMMON NAME OF THE SPECIE: Blueline Grouper
LOCATION: Found in the Indo-West Pacific, from western India to the Philippines, north to southern Japan (Honshu) and south to northern Australia. Some historical records from Madagascar, Réunion and Mauritius are considered likely misidentifications.
HABITAT: A tropical marine, reef-associated and non-migratory grouper. It generally prefers shallow dead or silty reefs, especially reef areas that provide shelter. The recorded depth range is 1–30 m, with the species usually found at 1–15 m. It is generally solitary.
SIZE: Maximum recorded length: approximately 34 cm total length.
DIET: Blueline Grouper is a carnivorous reef predator. It feeds on small fishes and crustaceans, using its grouper body shape and mouth to capture animal prey around reef structures.
FACT: It belongs to the grouper family, Epinephelidae. Its scientific name is Cephalopholis formosa. The species was originally described by George Shaw in 1812. It has a relatively compact, fusiform/normal body shape with an oval cross-section.
