Siamese Crocodile
This species is the most understudied crocodile of the family. Few information is known about its history and life cycle especially in regards to its reproduction cycle.
Known Facts to Date:
-
In the wild there are about 250 adult species left. Many human impacts have resulted in the species losing a large amount of its habitat and numbers in the wild. A most notable cause would to the war conflicts residing around Vietnam, Laos, and Cambodia. No only causing human fatalities the war impacted the Siamese ecosystem through land mines to aerial bombardment.
-
Like lost Crocodilia, a Siamese Crocodiles daily intake consists of fish and snakes, but also crabs, insects, birds and small mammals. Meaningful consumption of humans by this species has not been documented or recorded.
-
Females build mound nests by means of gathering plant debri and mixing it with mud, apart form that not much is known. However, in captivity during April to May the species lay 20 - 50 eggs. Once they hatch the female then introduced the to the water.
Human Impact on Siamese Crocodile
Siamese Crocodiles are listed as ‘Critically Endangered’ on the IUCN Red List of Threatened Species and are currently one of the most under-studied species that was reported as “Extinct in the wild” in the year 1992. National Geographic's resident herpetologist Dr. Brady Barr, was filming in Cambodia when she coincidentally caught one on camera, this siting led to further exploration, which then confirmed that small numbers where still alive in the wild.
As human we play a large role in their struggle for survival. Once found throughout Southeast Asia, today it mainly occurs in Cambodia where there are no more than 5,000 individuals. One must understand that the increase of human population in their range has caused an increase in human disturbance within their environment. The disruption is caused by habitat degradation and the need to build more homes which has forced the species out of their natural habitat. Another form of habitat degradation is the proposed hydroelectric power dams that are scheduled to be built. This contraption will cause wetland loss and alter natural flooding and dry seasons causing the need for a dramatic adaptation to that change. Lastly, the implementation of such dams may be the reason for a loss of at least half of the species remaining population and a large amount of aquatic life in the years to come. Hydroelectric power dams have been know to be very detrimental causing many fatalities due to aquatic life being sucked into turbine blades. Reservoir water is usually more stagnant than normal river water. As a result, the reservoir will have higher than normal amounts of sediments and nutrients, which can cultivate an excess of algae and other aquatic weeds. These weeds can crowd out other river animal and plant-life, and they must be controlled through manual harvesting or by introducing fish that eat these plants. In addition, water is lost through evaporation in dammed reservoirs at a much higher rate than in flowing rivers (www.ucsusa.org). The species has also been taken into alligator farms (which now house an estimated 700,000 in captivity) here they, breed and are raised for the purpose producing alligator meat and leather products.
