1 Banded butterflyfish - Chaetodon striatus: are usually seen swimming in pairs and is one of the numerous species of butterflyfish found on Caribbean reefs. The Banded Butterflyfish can be easily distinguished by the wide black bars (vertical stripes) on its sides.
2 Black Jackfish - Caranx lugubris: lives either individually or in small schools, and is known to school with other species. It is a predatory fish.
3 Caribbean sharpnose - Pufferanthigaster rostrata: is a tiny pufferfish with beautiful colorings. It can inflate itself with water when threatened. This is a defensive behavior which surprises predators and causes the fish to appear larger than it is. Please do not harass pufferfish in an attempt to make them inflate. Inflation is a stress reaction to a life-threatening situation.
4 Atlantic Sailfish -Istiophorus albicans: The Atlantic sailfish is a metallic blue fish with a large sail-like dorsal fin, long and pointed bill. Length is up to 3.15 m and the maximum published weight is 58.1 kg. ; swims at speeds up to 50 knots; feeds on the surface or at mid-depths on smaller pelagic fishes and squid.
5 French Grunt - Haemulon flavolineatum: French Grunts and Blue Striped-Grunts (Haemulon sciurus) are quite common and can be seen on nearly every shallow reef dive in the Caribbean. Grunts are so named because they can produce a grunting sound by grinding their teeth together and amplifying the noise with their air bladders!
6 Great Barracuda - Sphyraena barracuda: the Great Barracuda has a mouth full of sharp, pointed teeth. Its silver body with occasional black spots camouflages perfectly with just about everything, and it is common to find Great Barracuda hunting both along the surface of the water and over the reef.
7 Queen Angelfish - Holacanthus ciliaris: Most divers love angelfish; they are both beautiful and easy find during a dive. Queen Angelfish is a brilliant combination of blues, greens and yellows, and can be recognized bu the round spot on its forehead which looks like a crown with a bit of imagination.
8 Scrawled cowfish - Acanthostracion quadricornis: is one of several species of cowfish found in the Caribbean. Cowfish are a type of boxfish and can be recognized by the cow-like horns above their eyes. These fish are docile and relatively slow-moving unless threatened.
9 Spotted drum - Equetus punctatus: Spotted Drums are mismatched - they wear both spots and stripes! Adult Spotted Drums' unusual patterns make them a great favorite among divers.
10 Spotted trunkfish - Lactophrys bicaudalis: can be one of the most entertaining fish to watch on a dive. Not only is it cute - who doesn't love its puckered-lip look and its fancy white polka dots - but it always seems to be hunting for food. I most frequently find these smallish fish over sandy areas near the reef, where they blow little jets of water at the sand in an attempt to uncover food.
11 Trumpetfish-.Aulostomus maculates: These fish have long, thin, tubular bodies with trumpet-shaped mouths or snouts. Trumpetfish may be brown, reddish, bluish, or even bright yellow. Each of these colors can be used to blend in well with the reef.
12 The Porcupinefish - Diodon Hystric: is a large, white pufferfish covered with long spines. Divers needn't fear a Porcupinefish's quills -- Porcupinefish are slow-moving, docile giants. Like other pufferfish, the Porcupinefish can "puff up" by filling with water when threatened.
13 The Goliath Grouper - Epinephelus itajara: is a gigantic, predatory (don't worry, it doesn't hunt divers) fish that reaches up to six feet in length! This grouper can darken or lighten its colors and patterns to camouflage with its environment. Divers can watch it change colors as it swims between different parts of the reef or chases down a fish.
14 Yellow Goatfish - Mulloidichthys martinicus: many divers confuse Yellow Goatfish and Yellowtail Snapper (Ocyurus chrysurus) because of their similar coloration and the fact that they may school together in large groups on shallow reefs.
15 Red Lionfish - Pterois volitans: unfortunately, lionfish have become a common sight in the Caribbean. Lionfish, while beautiful, are an invasive species from the Indo Pacific. With no natural predators in the Caribbean, lionfish populations have skyrocketed over the last 10 years.Lionfish feed on young reef fish, who have not yet had the opportunity to reproduce. This has decimated reef fish populations in many areas of the Caribbean.
16 Brown garden eel - Heteroconger longissimus: Size up to 50 cm.Found in colonies in sand near coral reefs, down to 60 meters. Head and upper body extend from the burrow. Continuously move in wave-like motions to catch plankton.
17 Porkfish - Anisotremus virginicus: is a Grunt from the Western Atlantic. It occasionally makes its way into the aquarium trade. It grows to a size of 40.6cm in length.
18 Green Moray - Gymnothorax funebris: The moray’s muscular, scaleless body is laterally compressed (flattened side to side). The dorsal and anal fins are continuous with the short tail, or caudal fin, giving the appearance of a single fin running from the top of the head, along the back, around the tail, and underneath forward to mid-body. It has neither pelvic nor pectoral fins. The green moray has conspicuous, tube-like nostrils and finds its prey mostly using its sense of smell.
19 Yellow stingray - Urobatis jamaicensis: are found in the shallow coastal environments of the tropical western Atlantic Ocean. They bury themselves in the sand and move along with the ocean currents. They swim by rippling or undulating their bodies in waves, or by flapping their sides like wings, making them appear to glide as if in underwater flight.
20 Squirrelfish.Holocentrus adscensionis: Squirrelfish have spiky fins (which remind me of a mohawk) and big dark eyes. In fact, Squirrelfish are nocturnal, and they use their big, sensitive eyes to hunt for prey in minimal light. These night owls are typically found loafing around in dark areas of the reef during the day, but can be seen in the open on night dives.
