Most divers have their favourite marine creatures. Some like the big stuff like Whale Sharks and Manta Rays. Others like macro diving and seahorses, flamboyant cuttlefish and other incredible macro wonders.
 

Barracudas

The barracuda is a ray-finned fish known for its large size and fearsome appearance. Its body is long, fairly compressed, and covered with small, smooth scales. Some species could reach up to 1.8m in length and 30 cm in width.

Batfish

Batfish are found in warm and temperate seas. Batfishes have broad, flat heads and slim bodies and are covered with hard lumps and spines. Some species have an elongated, upturned snout. Batfishes grow at most about 36 cm (14 inches) long. They are poor swimmers and usually walk on the bottom on thickened, limblike pectoral and pelvic fins. Most live in the deep sea, but some inhabit shallow water.

Caribbean reef shark

The Caribbean Reef Shark is no stranger to divers of the Florida-Bahamas-Caribbean region. It is one of the most abundant large sharks in the area, especially on outer parts of coral reefs, often participates in organized shark feeds in the Bahamas. As a result, the Caribbean Reef may be one of the most frequently photographed of sharks.
 

Clownfish

Clownfish, sometimes called anemone fish are brightly coloured fish with three white stripes. They can be orange like Nemo, but some species can be yellow and white or even blue and white. There are approximately 28 species of clownfish. They live at the bottom of the Indian and Pacific oceans as well as the Great Barrier Reef and the Red Sea.

Eagle Ray

The eagle rays are a group of cartilaginous fish that are part of the family of Myliobatidae.  Eagle rays are basically large species of rays that unlike many ray species, tend to live in the open ocean rather than on the bottom of the sea.
 

Grey Reef shark

The grey reef shark is one of the most common species of shark found in the warm waters of the Indian and Pacific Oceans. Grey reef sharks are generally found in the coastal regions and along continental shelves from the Middle East to the islands in the deep Pacific.

Grouper

Groupers are not built for long-distance fast swimming. They can be quite large, and lengths over a metre and weights up to 100 kg are not uncommon. They swallow prey rather than biting pieces off it, habitually fish, octopuses, and crustaceans. According to the film-maker Graham Ferreira, there is at least one record, from Mozambique, of a human being killed by one of these fish...

Hammerhead shark

The hammerhead shark has a wide, thick head with the eyes at the margins. The head is indented at the center of the "hammer," which is almost rectangular in shape. This shark is gray-brown above with an off-white belly. The first dorsal fin (the large fin on the top of the shark that most people associate with sharks) is very large and pointed.

Manta Ray

The manta ray is the largest species of the rays. It ranges throughout tropical waters of the world, typically around coral reefs. Mantas have a tail similar to stingrays, but they have lost their stinger and are harmless to divers. They frequently visit cleaning stations where small fish such as wrasse, remora, and angelfish swim in the manta's gills and over its skin to feed, in the process cleaning it of parasites and dead tissue.

Moray Eel

Moray eels occur in all tropical and subtropical seas. They live in shallow water among reefs and rocks and hide in crevices. They differ from other eels in having small rounded gill openings and in generally lacking pectoral fins.

Napoleonfish

Adults are commonly found on steep coral reef slopes. They are one of the few predators of toxic animals such as the sea hare and boxfish and have even been reported preying on crown-of-thorns starfish. This species actively selects branching hard and soft corals and seagrasses at settlement. The species is most often observed in solitary male-female pairs, or groups of two to seven individuals.
 

Turtles

Sea turtles are beautiful, efficient animals that travel the world's oceans and know to return to the beach where they were born to lay their eggs. They have been in existence for millions of years and flourished until the last 100 years when they became endangered by human activities.

Whale Shark

The whale shark is a slow-moving filter feeding shark, the largest living fish species.It inhabits all tropical and warm-temperate seas and migrate every spring to the continental shelf of the central west coast of Australia. The coral spawning of the area's Ningaloo Reef provides the whale shark with an abundant supply of plankton. Although massive, whale sharks are docile fish and sometimes allow swimmers to hitch a ride.

White tip reef shark

These easily identified sharks earned their common name from the distinct white tips on their dorsal and upper tail fins. Long, slender bodies allow whitetips to maneuver through crevices and caves in their coral reef habitats.
