There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.

Black caiman (Melanosuchus niger)
The black caiman has dark-coloured, scaly skin. The skin coloration helps with camouflage during its nocturnal hunts, but may also help absorb heat (see thermoregulation). The lower jaw has grey banding (brown in older animals), and pale yellow or white bands are present across the flanks of the body, although these are much more prominent in juveniles. This banding fades only gradually as the animal matures. The bony ridge extending from above the eyes down the snout, as seen in other caiman, is present. The eyes are large, as befits its largely nocturnal activity, and brown in colour.The black caiman is one of the largest extant reptiles. It is the largest predator in the Amazon basin it is the largest member of the family Alligatoridae. Most adult black caimans are 2.8 to 4.26 metres (9.2–14 ft) in length, with a few old males growing larger than 5 m (16 ft) and exceeding a weight of 400 kg (880 lb). The black caiman broadly overlaps in size with the American alligator (Alligator mississippiensis), although it is on average larger at maturity. In some areas (such as the Araguaia River) this species is consistently reported at 4 to 5 metres (13–16 ft) in length, much larger than the alligator (which rarely even reaches 4 meters).
Larger specimens can virtually take any South American terrestrial or riparian vertebrate unfortunate enough to encounter them. Large prey can include other species of caiman, deer, peccaries, tapirs, anacondas, giant otters, and domestic animals including pigs, cattle, horses and dogs.

The false gharial (Tomistoma schlegelii )
The false gharial has one of the slimmest snouts of any living crocodilian, perhaps comparable to the slender-snouted crocodile and the freshwater crocodile in the extent of slenderness, only that of the gharial is noticeably more slim. The false gharial is a large crocodilian. Three mature males kept in captivity measured 3.6 to 3.9 m (11 ft 10 in to 12 ft 10 in) and weighed 190 to 210 kg (420 to 460 lb), while a female measured 3.27 m (10 ft 9 in) and weighed 93 kg (205 lb). Females have been recorded at lengths of up to 4 m (13 ft 1 in) and males have been confirmed at lengths of up to 5 m (16 ft 5 in). The false gharial has the losgest skull of any extant crocodilian, undoubtedly aided by the great length of the slender snout. Out of the eight longest crocodilian skulls from existing species that could be found in museums around the world, six of these belonged to false gharials. The longest crocodilian skull belonging to an extant species was of this species and measured 84 cm (33 in) in length, with a mandibular length of 104 cm (41 in). Most of the owners of these enormous skulls surprisingly had no measured (or even ancedotedly claimed) total measurements, but based on the known skull-to-total length ratio for the species, they would measure approximately 5.5 to 6.1 m (18 ft 1 in to 20 ft 0 in) in length.
False gharials are native to Peninsular Malaysia, Sarawak, and Indonesia (Sumatra, and Borneo), but were extirpated in Singapore and Thailand.
The false gharial was thought to have a diet of only fish and very small vertebrates. But more recent evidence and observation indicate that it has a generalist diet despite its narrow snout. In addition to fish and smaller aquatic animals, mature adults prey on larger vertebrates, including proboscis monkeys, long-tailed macaques, deer, water birds, and reptiles.

Cuvier's dwarf caiman (Paleosuchus palpebrosus)

Is most commonly found in the wetlands of Brazil, French Guiana, Surinam, Guyana, and Venezuela. Widespread throughout the Orinoco and Amazon basins, P. palpebrosus inhabit areas extending from Colombia, Venezuela, and the Guianas south to Sao Paulo and the upper Rio Paraguay in southern Brazil and west to the Rio Pastaza in Ecuador. (Grenard, 1991)
This species can be found near rivers and inundated savanna areas including the Orinoco and Amazon rivers, as well as those in eastern Paraguay. This species prefers clean, clear, fast-moving streams or rivers in forested areas containing waterfalls and rapids. Paleosuchus palpebrosus mostly inhabit fordable freshwater, avoiding salty, briny waters.
This species is the smallest of the alligator family. Males grow to about 1.3-1.5 meters, while the females grow to 1.2 meters. They can reach a mass of about 6-7 kg.

Paleosuchus trigonatus - Schneider's smooth-fronted caiman
Paleosuchus trigonatus is found in both the Amazon and Orinoco river basins, within the forested regions surrounding shallow streams. Their range covers a wide area in South America, from Peru in the west to French Guiana in the east (Ross,1989; Britton, 2001).
This species is found in and around cool, fast-flowing forest streams and rivers, often near waterfalls or rapids. It seems to prefer cooler water than other crocodilians (Ross, 1989; Alderton, 1991; Britton, 2001).
Paleosuchus trigonatus is the second smallest species of crocodilian in the world. Males of this species will grow to a length ranging from 1.7 to 2.3m, while females generally peak at 1.4 meters.
P. trigonatus and it’s relative, P. palpebrosus are born with brown eyes, as opposed to other crocodilians, which have yellow eyes. Both species also lack a ridge nestled between the eyes that is more typical in the related genera Caiman and Melanosuchus, hence the common name "smooth-fronted" caimans.

The Cuban crocodile (Crocodylus rhombifer)
It is a small species of crocodile found only in Cuba. Typical length is 2.1–2.3 m (6.9–7.5 ft) and typical weight 70–80 kg (150–180 lb). Large males can reach as much as 3.5 m (11 ft) in length and weigh more than 215 kg (474 lb). Despite its modest size, it is a highly aggressive animal, and potentially dangerous to humans.
Today, the Cuban crocodile can only be found in Cuba's Zapata Swamp and the Isle of Youth, and it is highly endangered. It formerly ranged elsewhere in the Caribbean. Fossils of this species have been found in the Cayman Islands and the Bahamas.
The Cuban crocodile appears to favor freshwater habitat such as swamps, marshes, and rivers and rarely swims in saltwater.
Diet and Hunting: small fish, arthropods, and crustaceans make up the diet of young Cuban crocodiles. Adults of the species feed mostly upon small mammals, fish, and turtles. They have blunt rear teeth, which aid in crushing the shells of their turtle prey. Cuban crocodiles also demonstrate the jumping feeding technique seen in other crocodilians such as the American alligator. By thrusting with their powerful tails, they can leap from the water and snatch small animals from overhanging branches.

The gharial (Gavialis gangeticus)
The gharial also known as the gavial, and the fish-eating crocodile, is a crocodilian of the family Gavialidae, native to the northern part of the Indian Subcontinent. The global wild gharial population is estimated at fewer than 235 individuals, which are threatened by loss of riverine habitat, depletion of fish resources, and entanglement in fishing nets. As the population has declined drastically in the past 70 years, the gharial is listed as Critically Endangered on the IUCN Red List.
The gharial is one of the longest of all living crocodilians, measuring up to 6.25 m (20.5 ft), though this is an extreme upper limit, as the average adult gharial is only 3.5 to 4.5 m (11 to 15 ft) in length. With 110 sharp, interdigitated teeth in its long, thin snout, it is well adapted to catching fish, its main diet. The male gharial has a distinctive boss at the end of the snout, which resembles an earthenware pot known in Hindi as ghara. The gharial's common name is derived from this similarity.

The gharial (Gavialis gangeticus)
Distribution: Its distribution is now limited to only 2% of its former range.
In Nepal, small populations are present and slowly recovering in tributaries of the Ganges, such as the Narayani-Rapti river system in Chitwan National Park and the Karnali-Babai river system in Bardia National Park.
In India, small populations are present and increasing in the rivers of the National Chambal Sanctuary, Katarniaghat Wildlife Sanctuary, and Son River Sanctuary. Another small population exists in the rainforest biome of Mahanadi in Satkosia Gorge Sanctuary, Odisha, where they apparently do not breed.[16] In 2008, a population of about 100 individuals was recorded in Corbett Tiger Reserve. In 2010, several individuals were recorded in the Gandaki River downstream the Triveni barrage west of Valmiki Tiger Reserve and adjacent to Sohagi Barwa Wildlife Sanctuary.
