Alligators Gars
Alligator, Fish or Both? The alligator gar — an ancient fish that has existed for 100 million years — roams the rivers, streams and bayous of the southeastern United States. It gets its name from its alligator-like snout and its double row of dagger sharp teeth. Unlike most of its close relatives, the alligator gar can breathe air and survive above water for up to two hours. Its body is covered in an armor plating of diamond-shaped, enamel-coated ganoid scales, and it's been said that this shining armor can produce sparks when struck by an axe.
The Devil Fish: The alligator gar stands accused of vicious human attacks, most notably at Lake Pontchartrain in Louisiana. A New Orleans newspaper once published an article contending that the alligator gar is more dangerous to human life than the "man-eater shark." But little evidence exists to suggest that this fish is actually aggressive towards humans, raising the question of whether the alligator gar has been wrongly accused of attacks perpetrated by an animal with a real track record of violence — the American alligator.

Devil Fish
It is larger than the lesser devil ray, growing to a maximum length of 5.2 metres (17 ft), and it possesses a spiny tail. The species feeds on crustaceans and small schools of fish.
The population of the Devil fish is 400. They can be found mainly in the Mediterranean Sea. The population of the Devil fish is decreasing is due to the accidental takes in swordfish pelagic driftnets. They are also accidentally caught by fishermen.
The devil fish or giant devil ray (Mobula mobular) is a species of eagle ray, family Myliobatidae. They are most common in the Mediterranean Sea and can be found elsewhere in the Eastern Atlantic Ocean, off the southwest coast of Ireland and south of Portugal.
It is larger than the lesser devil ray, growing to a maximum length of 5.2 metres (17 ft), and it possesses a spiny tail. The species feeds on crustaceans and small schools of fish.
The devil fish has a limited range and a low rate of reproduction. As a result it is sensitive to environmental changes. The main threats to this species come from pollution in the Mediterranean and accidental, unintended capture in various fishing equipment including trawls, tuna traps, and dragnets meant for swordfish, none of which are intended to ensnare Giant Rays. The 2004 IUCN Red List listed the devil fish as a vulnerable species, but in 2006 it was reclassified as an endangered species.

Giant Sturgeon Fish
One of the oldest families of bony fish in existence, sturgeon are native to subtropical, temperate and sub-Arctic rivers, lakes and coastlines of Eurasia and North America. They are distinctive for their elongated bodies, lack of scales, and occasional great size: sturgeons ranging from 7–12 feet (2-3½ m) in length are common, and some species grow up to 18 feet (5.5 m). Most sturgeons are anadromous bottom-feeders, spawning upstream and feeding in river deltas and estuaries. While some are entirely freshwater, very few venture into the open ocean beyond near coastal areas.
As one of the giant fish that ever existed, sturgeon fish can grow to tens of years, it was noted that there are fish capable of reaching the age of 100 yr. With long life spans, growth is also quite slow sturgeon fish including the reproduction and breeding. Making it very vulnerable to extinction and less fishing bertangguna responsibility.
Several species of sturgeons are harvested for their roe, which is made into caviar — a luxury food which makes some sturgeons pound for pound the most valuable of all harvested fish. Because they are slow-growing and mature very late in life, they are particularly vulnerable to exploitation and to other threats, including pollution and habitat fragmentation. Most species of sturgeons are currently considered to be at risk of extinction, making them more critically endangered than any other group of species.
Sturgeon is the common name used for some 26 species of fish in the family Acipenseridae, including the genera Acipenser, Huso, Scaphirhynchus and Pseudoscaphirhynchus. The term includes over 20 species commonly referred to as sturgeon and several closely related species that have distinct common names, notably sterlet, kaluga and beluga. Collectively, the family is also known as the true sturgeons. Sturgeon is sometimes used more exclusively to refer to the species in the two best-known genera, Acipenser and Huso.
