That Reptile Blog – Reptile, Amphibian and Exotic Pet Care and Information

 In Part 1 of this article I introduced Hagen’s new Smart Plants, an exciting line of realistic artificial plants (Bromeliads and Scindapsis) that contain small water-holding pools at their bases.  When properly positioned in a terrarium, they provide naturalistic sites into which female Poison Frogs can deposit their tadpoles.  Today we’ll see how other amphibians and reptiles can make use of this new and much-needed innovation.

Arboreal Reptiles

In the wild, most highly arboreal snakes and lizards find all the water they need without ever setting foot or belly on the ground.  Captives, especially high-strung or wild caught individuals, may be stressed if forced to do so.   Read More »

Tortoises are among the most popular of reptile pets, and many folks now realize the importance of a proper diet, UVA and UVB light, and heat.  Yet many well-meaning tortoise enthusiasts continue to provide their pets with grossly inappropriate accommodations – a situation that is fueled by those pet store employees who recommend glass aquariums to first-time owners.

A recent article in the journal IRCF Reptiles and Amphibians (V17, 1) provides evidence that the African Rock Python (Northern African Python, Python sebae), may have established a breeding population in southern Florida.  The huge constrictors are adapted to take small antelopes and other large animals, and have been killed and consumed people in their native habitat.

Florida’s Introduced Constrictors

At least 45 species of non-native reptiles and amphibians have established breeding populations in Florida; many others have been observed but are not known to be reproducing.  Among these are 2 of the world’s largest snakes, the Burmese Python and the Boa Constrictor.  Other large constrictors, including the Green Anaconda, Yellow Anaconda and White-Lipped Python, have been found at large in Florida.

Anacondas and others Established?

Given the extent of Florida’s wetlands and other densely-vegetated habitats, it is not unlikely that reproduction of other species has occurred unseen.  Anacondas, being aquatic, are especially difficult to find.  Years ago, I was told by a reliable source that an entire litter of Green Anacondas escaped from a roadside zoo near Florida City in the early 1970’s…nothing would surprise me at this point!

Northern African Python Study

The article mentioned above looked at Northern African Python sightings and captures in south Florida from 2002-2009.  In that period, 7 individuals were found in a small (less than 10 square miles) area in Dade County.  Among the captured snakes was an 15.5 foot-long adult female with eggs forming in the oviduct, reproductively active males, and several young-of-the-year.  The ages and sexes of these snakes, and their proximity to one another, suggests a breeding population.

Also notable is the fact that the capture sites were less than 1 mile from the border of the Everglades, an immense habitat that could easily hide other African Rock Pythons.

Recent meals – a Domestic Turkey and a Boat-tailed Grackle – were recovered from 2 of the snakes.

Python Hybrids

The African Rock Pythons were found in an area that abuts or overlaps with the range of Florida’s introduced Burmese Pythons.  The 2 species will mate with one another in captivity; the fertility of the resulting hybrids, and their possible affect on south Florida ecosystems, bears further study.

Many interesting amphibian and reptile field research reports are published in professional journals such as Copeia, Herpetologica and Herpetological Review, and are not available on the internet.  Unfortunately, such journals are usually quite expensive (if well-worth the price).  From time to time I’ll provide summaries of interesting articles that I come across.  Today’s report is drawn from Autumn, 2010 publications and covers 2 unusual feeding records.  The observations were made in Florida and, as might be expected, both predator and prey (Cuban Treefrog, Spectacled Caiman, Walking Catfish) were non native species!

Hello, Frank Indiviglio here.  Please see Part 1 of this article to read about the conservation of the Marsh Crocodile (Crocodylus palustris) and to see what it’s like to work with them in captivity. 

Natural History

Marsh Crocodiles are aptly named – despite being powerful swimmers, they favor the calm, plant-choked waters of swamps and marshes over swift-moving rivers (the species name, “palustris”, is a reference to their habitat).

Their range extends from Bangladesh, Nepal and Pakistan through India and Sri Lanka.  Read More »
