TAXONOMY
Kingdom:Animalia
Phylum: Chordata
Actinopterygii (ray-finned fishes)
Perciformes (Perch-likes)
Pomacanthidae (Angelfishes)

Genus/species: Holacanthus tricolor

GENERAL CHARACTERISTICS: Like their close relatives the butterflyfishes, they have a deep, laterally compressed body, a single and a unnotched dorsal fin. The most observable difference between the two families is the long spine at the corner of the preopercle common to angelfishes.

H. tricolor has a yellow anterior body with the remaining parts of body black. The caudal fin is entirely yellow.
Maximum length of approximately 12 inches (35 cm)

DISTRIBUTION/HABITAT: Western Atlantic: Georgia (USA), Bermuda, and northern Gulf of Mexico to Santa Catarina, Brazil among rock jetties, rocky reefs and rich coral areas.    Depth range 3 – 92 m (10-300 ft)

DIET IN THE WILD: Rock Beauty Angelfish feeds on tunicates, sponges, zoantharians and algae.

REPRODUCTION/DEVELOPMENT: Pair bonding suggests a monogamous relationship. Pairs usually consist of one small and one large fish as well. Pairs will spawn by slowly rising up in the water column while bringing their bellies close together, and releasing large amounts of eggs and sperm. A female can release anywhere from 25 to 75 thousand eggs each evening. This can total as many as ten million eggs for the duration of the spawning cycle. The eggs are transparent and pelagic, floating in the water column hatching in 15 to 20 hours becoming “pre-larval” angelfish attached to their large yolk sac. Has no functional fins, no eyes, or gut. After about 48 hours the yolk is absorbed developing into true larvae feeding on plankton. Growth is rapid and 3 to 4 weeks after hatching the fish will reach about 15-20 mm (0.6-0.8in) and will settle on the bottom.

CONSERVATION: IUCN  Least Concern

REMARKS: Reports of ciguatera poisoning

TAXONOMY
Kingdom: Animalia
Phylum: Chordata
Class: Actinopterygii (ray-finned fishes) 
Order: Perciformes (Perch-likes) 
Family: Scaridae (Parrotfishes)

Genus/species: Scarus iseri

GENERAL CHARACTERISTICS: Parrotfish owe their name to the shape of their mouth. Instead of teeth they have two beak-like plates, like parrots. They have even rows of large, noticeable scales on their bodies. 

Terminal phase: Body blue to green, with a gold to yellow spot or stripe above and behind the pectoral fin. Dorsal fin with a distinct pink, yellow or orange stripe down the middle that is broken by blue to green linear markings. Tail dark blue or green, with yellow or orangish linear markings between the borders.
Initial and juvenile phases: Body with three black stripes, two white stripes and a white belly, often with thin, broken silver, yellow or dark stripes. Usually yellow smudge on the nose, occasionally with yellow on the ventral fins, belly or tail. Tail without dark borders.
Size up to 35 cm.

Striped Parrottfish19431680162_8165aba44c_k

DISTRIBUTION/HABITAT: Common Florida, Bahamas and Caribbean. Epibenthic, found over shallow, clear waters, generally over Thalassia beds and rocky or coral areas

DIET IN THE WILD: Feeds on plants.

REPRODUCTION: A protogynous hermaphrodite . Super males spawn individually with striped females, while sexually mature males in the striped phase spawn in aggregation.

TAXONOMY
Kingdom: Animalia
Phylum : Chordata
Class: Actinopterygii (ray-finned fishes)
Order: Perciformes (Perch-likes)
Family: Pomacanthidae (Angelfishes)

Genus/species: Pomacanthus paru

GENERAL CHARACTERISTICS: Like their close relatives the butterflyfishes, they have a deep, laterally compressed body and a single, unnotched dorsal fin. The most observable difference between the two families is the long spine at the corner of the preopercle common to angelfishes. Dorsal and anal fins trail. Bodies are covered in black scales except those at front from nape to abdomen, which are rimmed with golden yellow. Adults have a broad orange-yellow bar at the base of their pectoral fins and have a dorsal filament that is yellow.
Juveniles are jet black with circular bright yellow bands.
Max length:41 cm (16 inches), common length: 25.0 cm (10 inches).

DISTRIBUTION/HABITAT: Western Atlantic: Florida, USA and Bahamas to Brazil, including the Gulf of Mexico and the Caribbean Eastern Atlantic: off Ascension Island to the west coasts of Africa in shallow reefs. 

Depth range 3 – 100 m (10-90 feet)

Juvenile below

French Angelfish

 

DIET IN THE WILD: P. paru are omnivores feeding on  sponges, algae, bryozoans, zoantharians, gorgonians and tunicates.

REPRODUCTION: French Angelfish are oviparous and monogamous. Spawning pairs are strongly territorial, with usually both members vigorously defending their areas against neighboring pairs.

CONSERVATION: IUCN; Least concern.

REMARKS: The tall, narrow bodies can turn quickly and maneuver down into narrow cracks between the corals to hunt prey and avoid predators. They swim by rowing with their pectoral fins.

Juveniles tend cleaning stations where they service a broad range of clients, including jacks, snappers, morays, grunts, surgeonfishes, and wrasses. At the station the cleaner displays a fluttering swimming and when cleaning it touches the clients with its pelvic fins.

Ciguatera poisoning may rarely occur from eating French angelfishes.

Kingdom: Animalia
Phylum: Chordata
Class: Actinopterygii (ray-finned fishes)
Order: Perciformes (Perch likes)
Family: Chaetodontidae (Butterflyfishes) The name “Chaetodontidae” means “bristle-tooth”.

Genus/species: Chaetodon sedentarius.

Reef butterflyfish  Chaetodon sedentarius ChaetodontidaeIMG_5652

GENERAL CHARACTERISTICS: Silver body, yellow and black dorsal fin, and yellow tail; two vertical black bars, one on the head through the eye and a black bar across the caudal peduncle. Max length: 6 inches (15 cm). 

DISTRIBUTION/HABITAT: a tropical western Atlantic species, found in the waters of the Carolinas to northern South America, including the Gulf of Mexico and the Caribbean Lives in the shallows and as deep as the light restricts coral growth. ( 48-130 feet deep).

DIET IN THE WILD: Coral polyps, polychaete worms, shrimps, amphipods and hydroids. Can be quite acrobatic in its feeding, often swimming upside down to get into crevices where prey might be hiding.

REPRODUCTION: Found in pairs, suggesting monogamy. The larvae of butterflyfishes are unique from all other species of fish. The head is encased in bony armor and large bony plates extend backwards from the head. These larvae, called “tholichthys,” grow to about 20mm, after which they settle on the bottom during the night.

PREDATORS: Preyed upon by larger fish, such as moray eels, snappers, and groupers. If it can’t find cover, will defend itself by facing its predator with dorsal spines erected, suggesting a sharply distasteful meal.

CONSERVATION: IUCN:  Least concern (LC)

REMARKS: Gets its name from its flitting movements about the reef and its beautiful color pattern that resembles the movements and appearance of the insect.
