Golden Dorado

Golden Dorado are piscivores, eating a wide variety of prey fish. One of the dorado's favorite prey are sabalo, a type of schooling fish typically 1-4 kg in weight.

Golden Dorado live in the warm waters of the La Plata Basinand the Amazon systems in South America, specifically in Brazil (where it's called Dourado - from Ouro, the Portuguese for Gold) Argentina, Paraguay, Uruguay, and Bolivia, and also in the São Francisco River system in Brazil. The Golden Dorado is highly sought-after by anglers, both for its delicious taste and fighting ability.

Goldfish

It has no scales on its head and is toothless. It makes a point not to even have a genuine stomach. Yet, despite such apparent disadvantages, the goldfish is still the most widely kept pet in the world.

The goldfish is an end relative of the regular carp and, such as its cousin, it fails to possess much scales on the top of its head. As a result, the goldfish has been referred to as being bald. Also, in keeping with its closest relations, the goldfish has no teeth in its jaws. However, it does have grinding teeth in its throat.

Gobies

From record breakers to species with very unusual habits, gobies are among the most widespread and varied of all fish. Gobies also include some critically endangered species.

The male of the freshwater diminutive person dwarf goby is simply 0.4 creeps extended. A marine goby, known as Trimmatom nanus, is even smaller at 0.39 inches, while several others are only slightly larger. It is only since the early 2000s that the goby world record for the smallest vertebrate (animal with a backbone) on the planet has been beaten—by another fish, a relative of the carp known as Paedocypris, that only reaches a length of 0.3 inches.Not all gobies are tiny, though. Some, such as the violet goby, are relatively large and can grow to more than 22 inches in length. 

Great White Shark

It is many people’s worst nightmare. Yet, for all its awesome reputation, the superbly adapted great white shark has more to fear from humans than we have to fear from it.

The great white shark is the perfect hunting machine. It can detect prey from distances of over a mile. Then it homes in, using a battery of senses. These include the ability to detect electric impulses given off by the prey as well as chemical signals such as minute traces of blood. Its sight is also very keen, especially in clear water. The shark’s streamlined, torpedo-shaped body and powerful tail allow it to put on impressive bursts of speed so it can quickly approach any selected victim. It also has massive jaws and fearsome teeth that can inflict fatal injuries in a split second.

Grunion

On some Californian beaches there is a spectacle like no other during nights of a full moon. Millions of fish launch themselves ashore in an apparent mass suicide attempt.

Although for a fish to launch itself onto a beach may seem like a life-threatening action, it is in fact simply a spawning technique. It is used by one or two fish species, including the grunion and the capelin. Many of these fish die during these dangerous onshore excursions, but it is all in the

Gouramis

It appears amazing that a fish can suffocate. Yet this is absolutely what happens in some species, for example gouramis, if they are averted from surfacing customarily to take in a swallow of atmosphere.

Gouramis have developed to exist in waters that can end up being particularly level in oxygen. Under such conditions, most fish could sooner or later gag to passing. In gouramis, however, some of the gills have developed into special organs that are very efficient at absorbing oxygen directly from the

Guppy

Also once known as the “millions fish,” because of the large numbers in which it was found in the wild,  the guppy has been thrilling fishkeepers for  around a hundred years.

This species was initially named the millions fish, but the name guppy is utilized for the most part today. This is in respect of the Reverend Lechmere Guppy who uncovered this fish in Trinidad in the 1860s—granted that it had as a matter of fact been depicted a few years previous by the

Graywhale

Gray whales are long-distance travelers, feeding in the far north and breeding in the tropics. Every year gray whales migrate more than 12,000 miles. Because they nearly always travel in sight of land, these whales are easy to watch.

Gray whales are a fairly common sight along the  west coast of North America. In spring and fall, thousands of people travel there every year to see gray whales pass by on their long migrations. However, fifty years ago,these huge mammals were almost extinct. They had been hunted for hundreds of years for meat  and oil. The gray whale population had fallen to just a few thousand
