black caiman size
The impact of density/dependence on population dynamics and growth, as well as the net production rate at whatever density, are apparently unknown. Once common, it was hunted to near extinction primarily for its commercially valuable hide. The female then builds her nest - a mound of earth and plant matter, some 40 cm high and at least 1 m in diameter - on a site near water but not subject to flooding, often building over an earlier nest (31, 140). Other common names for this species include the musky caiman, the dwarf caiman, Cuvier's caiman, and the smooth-fronted caiman. [8] The female black caiman only breeds once every 2 to 3 years. Most adults grow to 120-200 cm, and weigh 7-40 kg. I think that Black Caiman are supposed come in one size but I found one that is huge. This species was classified as Endangered in the 1970s due to the high demand for its well-marked skin. Cuvier's dwarf caiman is a small crocodilian in the alligator family from northern and central South America. Most adult black caimans are 2.2 to 4.3 m (7 ft 3 in to 14 ft 1 in) in length, with a few old males growing larger than 5 m (16 ft 5 in). The black caiman shares its habitat with at least 3 other semi-amphibious animals considered apex predators and is usually able to co-exist with them by focusing on different prey and micro-habitats. Breeding occurs from May to August and 14–40 eggs are laid in July and August. However, specimens exceeding 6.1 m (20 ft) in length and weighing up to 1,089 kg (2,400 lb) have been recorded. A number of privately owned captive breeding establishments have recently been set up in Venezuela, providing a growing backlog of experience on the maintenance of this species in captivity. Mortality: Despite maternal care, there is nest depredation by coatis (140), Tegu lizards (148, 562) and other animals, and some nests are destroyed by flooding, trampling or human interference (egg collecting). They live in the Amazon River Basin, where they are one of the apex predators there. When group size per tank was increased from 15 to 35, mean growth dropped and individual variations increased. [11] [34] [35], Humans hunt black caimans for leather or meat. Commercial exploitation of adult caiman has had a very destructive impact on population due to the low capacity for recovery. The black caiman is structurally dissimilar to other caiman species, particularly in the shape of the skull. This has, in turn, led to increased agricultural and livestock losses. If someone else could check it out? [32] Scars on Amazon river dolphins suggest they may occasionally be attacked by black caimans. They'll typically bask upon open sandy banks. It is known from skull material found in the Brazilian and Peruvian Amazon, Colombian Villavieja Formation, Panamanian Culebra Formation and the Urumaco and Socorro Formations of northern Venezuela. The caiman’s status hasn’t been reassessed since 2000 when they were placed there. They have thick, scaly, heavily armoured skin. The mother will assist chirping, unhatched young to break out of the leathery eggs, by delicately breaking the eggs between her teeth. [11] [12] Sub-adult male specimens of around 2.5–3.4 m (8 ft 2 in–11 ft 2 in) will weigh roughly 95–100 kg (209–220 lb), around the same size as a mature female, but will quickly increase in bulk and weight. The morphology is quite different from other caimans but the bony ridge that occurs in other caimans is present. Spectacled caimans have now filled the niche of crocodilian predator of fish in many areas. [38]. [36] Most tales are poorly documented and unconfirmed but, given this species' formidable size, predation on humans can be fatal. The Black Caiman, Welcome To The Official Mark O'Shea Website, Central African slender-snouted crocodile (. The eggs hatch between 42 – 90 days after being laid. Then, the offspring stick close to their mom. [11][12] The black caiman broadly overlaps in size with the American alligator (Alligator mississippiensis), although it is on average larger at maturity.
[8], Compounding the conservation issues it faces, this species occasionally preys on humans. The Black Caiman is the largest living species of caiman, capable of reaching 16.5 feet long and reaching over a thousand pounds!
The black caiman (Melanosuchus niger) is a species of large crocodilian and, along with the American alligator, is one of the biggest extant members of the family Alligatoridae and order Crocodilia. This banding fades only gradually as the animal matures.
Reproduction: C. crocodilus takes at least six years to reach sexual maturity, corresponding to an approximate overall length of 114 cm (approximately 60 cm snout/vent) (242). Some feel that the findings should elevate the subspecies to full species status. [12] Unguarded clutches (when the mother goes off to hunt) are readily devoured by a wide array of animals, regularly including mammals such as South American coatis (Nasua nasua) or large rodents, egg-preying snakes and birds such as herons and vultures. Size helps the Black Caiman a lot, as its size can intimidate potential threats.
Its population in the Pantanal is about 10 million, and it is listed as least concern on the IUCN Red List. (2008). Although capable of living in saline environments, this species is rarely found in saltwater, but occasionally inhabits deltas and brackish lakes.

The total maximum length reported by Medem (377) was 240 cm for males and 173 cm for females, with maximum weights of 45 kg for males and 19 kg for females.
During the 65-84 day incubation period (various authors), the female guards the nest. 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. Products: Some indigenous people (Table 6) (and campesinos to a lesser extent) hunt caiman for its tasty but rather tough white meat, and they may sell it as salted and dried slabs (like fish).
