Morelet’s Crocodile - Crocodylus moreletii.
In: Crocodiles.Status Survey and Conservation Action Plan: 79-83.
Third Edition, ed. by S.C. Manolis and C. Stevenson. Crocodile Specialist Group: Darwin
Aus dem Inhalt:
Morelet’s crocodile is a medium-sized species (males to 4.5 m) occurring in the Atlantic lowlands of the Gulf of Mexico (Mexico) and the Yucatan Peninsula (Mexico, Belize and Guatemala). Knowledge of this species has increased rapidly over the past two decades, and recently a great deal of research has been conducted on its distribution and status in Mexico and Belize, nesting ecology, diet and foraging ecology, morphometrics, population ecology and ecotoxicology.

Australian Freshwater Crocodile - Crocodylus johnstoni.
In: Crocodiles.Status Survey and Conservation Action Plan: 66-70.
Third Edition, ed. by S.C. Manolis and C. Stevenson. Crocodile Specialist Group: Darwin.
Aus dem Inhalt:
The Australian Freshwater Crocodile was formally described as Crocodylus johnsoni intended to name the species after Mr. Robert Johnstone, but mispelt the name as “Johnson”. Cogger et al. (1983) reviewed the nomenclature and reinstated the name Crocodylus johnstoni, which is the name most commonly applied in the scientific and general literature, and in Australian State/Territory and Federal legislation. This correction was unnoticed by some (King and Burke 1989), so “Crocodylus johnsoni” still appears in some contexts (CITES and IUCN).

Gharial - Gavialis gangeticus.
In: Crocodiles.Status Survey and Conservation Action Plan: 139-143.
Third Edition, ed. by S.C. Manolis and C. Stevenson. Crocodile Specialist Group: Darwin.
Aus dem Inhalt:
Historically, G. gangeticus was found in the northern part of the Indian subcontinent, in the Indus (Pakistan), Ganges (India and Nepal), Mahanadi (India) and Brahmaputra (Bangladesh, India and Bhutan) River systems. The presence of the species in the Irrawaddy River system in Myanmar has also been reported. The Gharial is typically a resident of fl owing rivers with deep pools that have high sand banks and good fi sh stocks. Exposed sand banks are used for nesting. Although the function of the ‘ghara’ is not well understood, it is apparently used as a visual sex indicator, as a sound resonator, or for bubbling or other associated sexual behaviours.

Slender-snouted Crocodile - Crocodylus cataphractus.
In: Crocodiles.Status Survey and Conservation Action Plan: 54-58.
Third Edition, ed. by S.C. Manolis and C. Stevenson. Crocodile Specialist Group: Darwin.
Aus dem Inhalt:
Historically, C. cataphractus was widely distributed throughout West and Central Africa, but recent surveys suggest that its distribution has changed as a result of local extirpations. While relatively little is known about the ecology of the species, it appears to prefer forested rivers and other densely vegetated bodies of water (i.e. reservoirs and freshwater lagoons), but has also been found in sparsely vegetated, gallery habitats within savannah woodland.

Siamese Crocodile - Crocodylus siamensis.
In: Crocodiles.Status Survey and Conservation Action Plan: 120-126.
Third Edition, ed. by S.C. Manolis and C. Stevenson. Crocodile Specialist Group: Darwin.
Aus dem Inhalt:
Crocodylus siamensis is one of the world’s most endangered crocodilians. In 1992 it was reported as virtually extinct in the wild and in 1996 it was accorded IUCN Red List status of ‘Critically Endangered’. Since 1996, new status assessments have resulted in the discovery of wild populations and information on its global distribution and ecology, although it remains one of the least known of crocodilians.The Siamese crocodile occurs in a wide range of freshwater habitats, including slow-moving rivers and streams, lakes, seasonal oxbow lakes, marshes and swamplands. During the wet season, individuals disperse across fl ooded landscapes. The use of burrows excavated into the banks of rivers or lakes has been reported, with up to fi ve individuals utilizing a single burrow at one time. Generally preferring lowland elevations, the species has been recorded up to 600 m.

Cuban Crocodile - Crocodylus rhombifer.
In: Crocodiles.Status Survey and Conservation Action Plan: 114-118.
Third Edition, ed. by S.C. Manolis and C. Stevenson. Crocodile Specialist Group: Darwin.
Aus dem Inhalt:
The Cuban crocodile has the smallest known distribution of any extant crocodilian, and is currently restricted to Zapata Swamp (mainland Cuba) and Lanier Swamp (Isla de la Juventud). In the recent past the species was more widely distributed on the main island of Cuba. Skeletal material shows that this species was present on the Cayman Islands. The Cuban crocodile population of Zapata Swamp is restricted to a small area of approximately 300 km², on the southwestern portion of the peninsula, where the species is sympatric with the American crocodile (Crocodylus acutus). Lanier Swamp is a small wetland of approximately 100 km², situated on a west-east axis, across the central portion of Isla de la Juventud. Several hundred C. rhombifer have been released in Lanier Swamp since 1994, as part of an ongoing restocking program.

Saltwater Crocodile - Crocodylus porosus
In: Crocodiles.Status Survey and Conservation Action Plan: 93-113.
Third Edition, ed. by S.C. Manolis and C. Stevenson. Crocodile Specialist Group: Darwin.
Aus dem Inhalt:
Crocodylus porosus is considered the largest of the living crocodilians, with reported lengths of up to 6-7 m. Although accounting for far less human fatalities than the Nile crocodile, C. porosus preys on people when given the opportunity. It is one of the most widely distributed of all crocodilians, ranging from southern India and Sri Lanka, throughout southeast Asia, east through the Philippines to Micronesia, and down through Indonesia, Papua New Guinea and the Solomon Islands to northern Australia.

Best Practices: In the 21st Century, Taxonomic Decisions in Herpetology are Acceptable Only When Supported by a Body of Evidence and Published via Peer-Review.
Herpetological Review, 2013, 44(1), 8–23.
Einleitung:
Taxonomy, the scientific process by which natural groups are identified, described, named, and classified is an exciting research pursuit, not only because it makes an ndispensable contribution to biodiversity science but, at a more basic level, because it satisfies the human enjoyment of discovery. However, taxonomy has been an area of biological science in which errors, ethical transgressions, and clashes of egos have been particularly vicious and public, harkening back to the earliest days of the binomial system of nomenclature when Linnaeus (1737) named what he considered an insignificant weed (genus Siegesbeckia) after Johann Georg Siegesbeck, a contemporary and very vocal critic.

Black Caiman - Melanosuchus niger.
In: Crocodiles.Status Survey and Conservation Action Plan: 29-39.
Third Edition, ed. by S.C. Manolis and C. Stevenson. Crocodile Specialist Group: Darwin
Aus dem Inhalt:
The Black caiman is the largest member of the Alligatoridae, with adult males surpassing 4-5 m in length. The species is widely distributed throughout the Amazon River basin, but populations are also known from areas outside the Amazon; the Rupununi and upper Essequibo River drainages in Guyana, the Kaw and Approuague region of French Guiana, and the lower Oiapoque River (Amapá, Brazil/French Guiana border), with populations at Pointe Behague (French Guiana) and Cabo Orange (Brazil).
Today, M. niger is common throughout much of the Brazilian Amazon, and there are no reports of populations being locally endangered in the last 15-20 years. In 2007, the population was transferred to CITES Appendix II (Brazil 2007), a move that will facilitate managed commercial use.
