Sharks
The sharks are a very ancient group of fish, characterized by cartilaginous skeletons, skins covered in tiny, thornlike scales called placoid scales, five to seven gill slits, and powerful jaws equipped with rows of strong, sharp teeth. There are about 300 species, distributed widely throughout the world's seas but particularly in tropical waters, and although most are marine some enter estuaries, rivers, and creeks. They range in size from about 60 cm (2 ft) in length up to at least 18 m (60 ft); those found in Malaysian water are among the smaller species, up to 3.5 m (11 ft 6 in) long. The second group here are representative of the larger species, and range in length from just under 4 m (13 ft) up to about 9 m (30 ft) or more. Some are too big to be fished such as basking shark and whale shark, huge but generally placid sharks that feed mainly on plankton. The basking shark is the largest shark in temperate waters, possibly growing to 13.7 m (45 ft) and 20,000 kg (44,000 lb); the whale shark, found in tropical seas, is the world's largest fish and may exceed 15.2 m (50 ft) and 35,000 kg (77,000 lb). These largest verified specimens of these two sharks were a 12.27 m (40 ft 3 in) basking shark and 12.65 m (41 ft 6 in) whale shark. Some sharks like white shark and blue shark prefer to fish human instead of being fished. But here we hardly see these type of shark, so you are quite safe here. They are including thresher shark, shortfin mako, sixgill shark, tiger shark, smooth hammerhead, blue shark and white shark.
FISHING NOTES
Techniques
Trolling and drift fishing are the usual forms of shark fishing, but small sharks that venture into the inshore shallows are also taken by shore anglers, including saltwater fly fishers. Take care to avoid injury when handling sharks.
   Tackle
When shore fishing for shark, try a 3.4 to 3.7 m (11 to 12 ft) rod with a multiplier reel, 8.2 kg (18 lb) mono line with a wire leader, a 113 to 170 g (4 to 6 oz) weight, and hook sizes 4/0 to 6/0, or a medium to heavy saltwater fly outfit with a 30 cm (12 in) wire trace at the end of the tippet, and flies tied on 5/0 or 6/0 hooks. For trolling and drift fishing, the tackle depends on the size of the shark you expect to catch. For example, a 9.1 kg (20 lb) class outfit should suffice for small species such as spurdog, but for larger fish such as porbeagle and mako require 22.7 to 36.3 kg (50 to 80 lb) class tackle.
   Baits
Strips of fresh fish (such as mackerel, tuna or pollack) for small species, whole fish for larger ones. Most of the times, we hook shark by accident.
Note: Shortfin Mako and Blue Shark
The shortfin mako, also known as the mako or bonito shark, is probably the fastest-swimming shark, capable of speed bursts of up to 74 km/h (46 mph). Its maximum size is about 3.8 m (12 ft 6 in) and 506 kg (1,115 lb), and it makes spectacular leaps when hooked.

This beautifully colored (blue shark) and very streamlined shark is found in nearly all temperate and tropical waters, but rarely comes within about 24 km (15 miles) of the shore. It is a fast swimmer, capable of speed bursts of 39.5 km (24 1/4 mph), and travels great distances: two that were tagged off southwest England were later caught by anglers off Long Island, New York, about 5,630 km (3,500 miles) away. The blue shark grows to around 3.8 m (12 ft 6 in) and 151 kg (333 lb).

This huge shark (white shark), also known as the great white shark or man eater, has been known to attack swimmers, skindivers, and even boats, woooooppppssss!!!, but has itself been so merciless hunted that it is becoming endangered. It is primarily a fish of the deep ocean, but it sometimes enters shallow water in search of food such as seals, or even human. It also eats fish, shellfish, turtles, and seabirds, and averages 4.3 m (14 ft) but may reach over 11 m (36 ft). The largest fish ever caught by an angler was a 1,208 kg (2,644 lb) white shark, taken by Alf Dean at Denial Bay, South Australia in 1959, but my advise to you, if you sea this creature, run away, or hooked on your line, just cut the line unless you are properly equipped.
