Natural Predators - (FRR)
When having a look at the natural predators of reptiles one must regard this document as work in progress. Never the less it seems popular with what I would assume are school going kids looking for information on home work projects. So we had better do some more work on it and fast. This is what we have found to date.
Predation Snakes on other reptiles
There are a number of natural predators that prey on reptiles, and includes certain reptiles that will prey on other reptiles, such as :-
Cape Cobra, Cape Wolf Snake,
African Rock Python will predate on small Crocodiles and Monitors
Boomslang - Agamas, geckoes, chameleons
Twig or Vine snake - lizards frogs, snakes
Spotted Harlequin Snake - snakes, legless lizards, burrowing skinks
Coral snake - lizards
Shield nose snake - amphibians, lizards and other snakes
In addition we have mongoose, badgers, secretary birds, other raptors, wild dogs, leopards, to mention a few that have been known to attack a reptile if presented with the opportunity.
And then there is also the impact of domestic pets such as cats and dogs that will attack and kill more harmless reptiles.
Inbalance in nature
Caused by humans who protect one species, which results in an imbalance in the natural state. This could increase a predatory species that preys on a protected species such as Badgers and wild dogs on reptiles.
Predation on Turtles and Tortoises by a "Subsidized Predator"
Reptiles in game parks
The high concentration of animals in a relatively small area, increases the risk of predation.

Threats to Marine Turtles
The natural predation of turtle hatchlings is mainly caused by birds and adult Turtle are often taken by Tiger Sharks or attacked on the beach in some parts of the world by Pumas and other large predators. Man, however, is the biggest problem. Here is some more reading that we have found to date.

Extract : Threats to the marine turtle are on the rise which has drastic impact on their survival rate. Scientists believe that the presence of marine turtles in the marine ecosystem indicates the health of the sea. Threats to marine turtles are not just from natural predators like sharks and natural demographic changes but also from predators on land – humans and animals & birds alike.

Extract : The problem of hatchlings being eaten by dogs is compounded when the hatchlings are disorientated at night by beach-front lighting.
Of Turtles and Things - Mexican Meanderings
Extract : Not all the world heeded the message simultaneously, nor reacted with the same gusto. Demand for sea turtle eggs, oil, meat and shell was difficult to placate. The creatures were easy to find and kill, and offered no danger to the hunter. The international fishing industry still accounts for a large annual number of turtle kills through entrapment and drowning in nets. Turtle excluding devices (TEDs) for fishing nets are costly, and the industry objects strenuously to this added outlay. Ongoing pollution of the seas includes untold quantities of plastic bags, which to turtle eyes seem to bear an uncanny resemblance to a staple of their diet, the jelly-fish. Ingested, the plastic blocks the digestive tract, causing starvation.
