More than 30,000 different species of fish ply Earth’s oceans and bodies of fresh water. The beauty of many fish species is highlighted in fish stores, aquariums and in home collections. Some species, however, have darker, more terrifying aspects. A select few of these may attack human beings, while others might deliver a dose of poison when handled carelessly or not properly prepared for consumption. Here are 10 of the world’s most dangerous fish (part 1):

Puffer

Puffers are found in warm and temperate regions around the world, primarily in the sea but also, in some instances, in brackish or fresh water. They have tough, usually prickly skins and fused teeth that form a beaklike structure with a split in the center of each jaw.
Many species are poisonuos; a highly toxic substance, tetraodontoxin, is especially concentrated in the internal organs. Although this substance can cause death, puffers are sometimes used as food. In Japan, where the fishes are called fugu, they must be carefully cleaned and prepared by a specially trained chef.

Red Lionfish

Red Lionfish is noted for its venomous fin spines, which are capable of producing painful, though rarely fatal, puncture wounds. The fishes have enlarged pectoral fins and elongated dorsal fin spines, and each species bears a particular pattern of bold, zebralike stripes. When disturbed, the fish spread and display thair fins and, if further pressed, will present and attack with the dorsal spines.

Candiru

Candiru is a translucent and eellike, and it grows to a length of about 2.5 cm. The candiru feeds on blood and is commonly found in the gill cavities of other fishes. It sometimes also attack humans and has been known to enter the urethras of bathers and swimming animals. Once in the passage, it erects the short spines on its gill covers and may thereby cause inflammation, hemorrhage, and even death to the victim.

Great White Shark

Great white sharks are responsible for numerous unprovoked, and sometimes fatal, attacks on swimmers, divers, surfers, kayakers, and even small boats. A white shark tends to inflict a single bite on its human victim and then retreat. Many researchers maintain that attacks on humans stem from the shark’s curiosity.

Moray Eel

Moray eels differ from other eels in having small rounded gill openings and in generally lacking pectoral fins. Their skin is thick, smooth, and scaleless, sharp teeth, which enable them to seize and hold their prey but also to inflict serious wounds on their enemies, including humans. They are apt to attack humans only when disturbed, but then they can be quite vicious. Moray eels are eaten in some areas of the world, but their flesh is sometimes toxic and can cause ilness or death.
