They are believed to have been the main reason for the likely extirpation of the Cuban crocodile (Crocodylus rhombifer) from the Isla de la Juventud, Cuba. [11][19] Clutch size is 22 on average, but can range from 14 to 40. It is very light, yellowish-white with dark blotching. the Caiman crocodilus apaporiensis Medem, 1955 (called in English Rio Apaporis caiman), present in south-eastern Colombia. Breeding occurs from May to August and 14–40 eggs are laid in July and August. > crocodilus means "a crocodile" (Latin) > "Spectacled" refers to the intra-orbital (between the eyes) bridge of bone that lends a bespectacled appearance SUBSPECIES: Formerly C. sclerops. The believed-extinct Rio Apaporis caiman (Caiman crocodilus apaporiensis) has been rediscovered by Forrest Galante, wildlife biologist and host of Animal Planet’s EXTINCT OR ALIVE, and team, making history once again. A similar program released over 15,000 juveniles into wetlands from 2005 to 2009. Eggs are laid in July and August; the species very rarely nests in the winter, as the temperature is too low for the eggs. [15], The spectacled caiman can move rapidly when threatened, but is usually immobile, resting on shores or partly in water. © 2020 Discovery or its subsidiaries and affiliates. It has been confirmed to live in Brazil, Colombia, Costa Rica, Ecuador, El Salvador, French Guiana, Guatemala, Guyana, Honduras, Mexico, Nicaragua, Panama, Peru, Suriname, Trinidad and Tobago, and Venezuela, and may also be extant in Belize and Bolivia. [27], Magnusson, W.E. It is brownish-, greenish-, or yellowish-gray colored and has a spectacle-like ridge between its eyes, which is where its common name come from. [9] However, populations are not doing well in other countries, such as Peru. Its skin was often exported from South America and utilized primarily for leather; at least 6 million skins were exported from Colombia from 1996 to 2015. [1] About four million spectacled caimans are found in Venezuela and surveys have shown that it is expected to increase. Apaporiensis Caiman (Colombia): The genetic divergence between Caiman c. crocodilus and C. c. apaporiensis was found to be very low based on the mitochondrial genome, so there is no significant differentiation that supports the division of these two subspecies. [1] It has since been redescribed several times, including as Caiman sclerops by Schneider in 1801. Looking for a fun, educational, and zero-waste DIY project? [11], Usually hunting at night,[11] the diet of the spectacled caiman varies seasonally. They're planting 20 million trees, but they're on a deadline. [1] The subspecies C. c. crocodilus is on Appendix II of CITES,[3] C. c. apaporiensis Appendix I,[26] and C. c. fuscus Appendix II. Analysis of the samples, confirmed that the caiman Galante and team discovered are, in fact, the Rio Apaporis caiman. [9][18], The spectacled caiman uses nine different vocalizations and 13 visual displays to communicate with individuals of its species. [25] The spectacled caiman lives in parts of the Amazon rainforest that the black caiman was extirpated from. [10] The body mass of most adults is between 7 and 40 kg (15 and 88 lb), with males typically being considerably heavier than females. It is very light, yellowish-white with dark blotching. Males are known to communicate by moving their tail to a certain position, such as making it vertical or arched. The spectacled caiman (Caiman crocodilus), also known as the white caiman,[4] common caiman,[5] and speckled caiman,[6] is a crocodilian in the family Alligatoridae. Adult males can regularly reach 1.5 to 1.8 m (4.9 to 5.9 ft) while large mature ones grow to 2.0 to 2.5 m (6.6 to 8.2 ft), although relatively few get to the upper size. Species Caiman crocodilus Common caiman, Spectacled caiman. [13] The population in a single area can be determined the easiest by counting individuals in the dry season at night. [8] Throughout the 1970s and 1980s, the species was frequently traded, causing its population to decrease in some areas. Smaller specimens tend to eat more insects, while larger ones more frequently consume mammals and fish. Try creating a mini-garden using a convenient kitchen scrap: egg shells! See Galante and team make this massive discovery on EXTINCT OR ALIVE, airing on December 4 at 9P on Animal Planet or Animal Planet GO. However, harvesting of the skins of this caiman and others became very common in the 1950s, due to the declining stocks of crocodiles. Caiman crocodilus apaporiensis. [1], The spectacled caiman is a small to medium-sized crocodilian. Kingdom Animalia animals. [1], The spectacled caiman reaches sexual maturity from four to seven years old, at a length of 1.2 metres (3.9 ft) for females and 1.4 metres (4.6 ft) for males. [7], The spectacled caiman has four recognized subspecies:[5][8], The yacare caiman (Caiman yacare), while previously thought to be a subspecies of C. crocodilus, is now usually considered a separate species. and published a paper on it this year. NatureServe Explorer Species Reports -- NatureServe Explorer is a source for authoritative conservation information on more than 50,000 plants, animals and ecological communtities of the U.S and Canada. According to the Crocodilian Species List, it is probably a generalist species, being able to adapt to a variety of prey. [22] It is intolerant to cold climates, so its range is unlikely to expand to further north than Florida. Overall, the most common animals in this species' diet are crabs, fish, mammals, and snails. [12], The adult population of this crocodilian is estimated to be in the millions and stable. [1] It is reasonably resilient to hunting as well, as hunters usually focus on large males and the species reproduces at a small size. [19] Heat not only incubates the eggs, but also determines the sex of the developing caimans (temperature-dependent sex determination). [24], The spectacled caiman benefits from overhunting of competitive species which occupy the same home range, as this allows it to access resources normally lost to these other species. The smallest species is the Cuvier's dwarf caiman (Paleosuchus palpebrosus), which grows to 1.2 to 1.5 m (3.9 to 4.9 ft) long. Here's what you need to know to support their cause! “Finding not just one, but a thriving population of Rio Apaporis caiman, in an area that we we’re told was completely inaccessible to westerners—going against the odds and danger after years of research and planning—was a flurry of emotions, the strongest of which was massive excitement followed by sincere encouragement,” Galante said. [6] It is able to live in human-inhabited areas. [1], The spectacled caiman is listed as a species of least concern on the IUCN Red List, due to its large range and population globally, following two assessments as threatened in 1986 and 1988. [11] They are yellow with black spots, a coloration which fades away as they grow older,[9] with a length of 20–23 centimetres (7.9–9.1 in). crocodilus. (KSR #43) Act The believed-extinct Rio Apaporis caiman (Caiman crocodilus apaporiensis) has been rediscovered by Forrest Galante, wildlife biologist and host of Animal Planet’s EXTINCT OR ALIVE, and team, making history once again. Believed-Extinct Rio Apaporis Caiman Rediscovered. Galante and his dedicated crew embarked on a journey into the heart of a drug-controlled jungle, through harsh and lawless lands in hope of finding the Rio Apaprois caiman. The most common form of conservation is the use of cropping, which consists of manually reducing the numbers of several wild and abundant species. With a unique elongated snout and light-yellow skin, this crocodilian looks unlike any other in the world.
