My bearded dragon has rattlesnake toxins in its venom.

After spending a day researching Dr. Bryan Grieg Fry's work on reptile venoms I am beginning to have some realisation of the impact it will have on our understanding of reptile evolution, reptile venom and even the reptile trade.

Books will have to be rewritten and basically our biology trees for reptiles redrawn. Whilst we have know this for some two years, the more recent work on lizard venoms has highlighted the changes even further.

These venoms also offer some interesting medical opportunities.

I had an email today from someone who had photographed his cage making efforts and made a fake wall. While the cage is not finished, it looks good and he informs me that he intends to make some more reptile cages using my reptile cage plans. You can see some of his handiwork with homemade reptile cages here.

Should Reptile Keeping be Restricted to Native Animals?

This article is also published in the free newsletter (sign up here).

A recent email from a colleague in South Africa (to read what is happening with legislation to restrict the ownership of reptiles, click here) prompted me to consider this issue in a little more depth. I live in Australia, a country with quite stringent restrictions and regulations on the keeping of reptiles in many states. You must be licensed to keep reptiles in my state, although the licensing is not tracked excessively and is readily available to anyone over the age of 10. And you can only keep native reptiles.

In many ways the licensing has benefits for the keepers. Reptiles can only purchased from other licensed breeders or keepers. In theory the illegal trade, both endangered and common, is reduced, although I would not be naïve enough to suggest it is eliminated. There is plenty of evidence to suggest that it is thriving, at least at the international level.

These regulations have come about through a variety of reasons but I believe primarily for two reasons:

• the environmental and economic damage caused by the introduction of invasive and alien species and the resulting high rate of extinction of endemic animals. These introduced animals include cane toads, foxes, cats, rabbits, dogs, pigs, goats, water buffalo, horses, Indian mynas, starlings, sparrows, pacific sea star and crown of thorns star. All have had significant impacts on native fauna and flora – 19 species of small mammals have become extinct from cats, foxes and dogs in the last 100 years;
• the high level of endemism among Australian animals due to their isolation, together with threats from settlement and land practices has endangered the survival of a large number of them. This has resulted in Australia passing wide-ranging federal and state legislation protecting both endangered and secure species (although there is still is much more to be done) in an effort to reduce the alarming extinction or endangerment rate.

All of the introduced animals were released in significant numbers (only 24 in the case of rabbits but that is still significant – they breed like rabbits), either to eliminate pests, for hunting, as pets or accidentally. As a result, most have been able to breed extensively and compete with the local fauna for food and habitat (Australia has the only known population of feral wild camels in the world). In many cases they destroy the local animals by preying on them, eg foxes, dogs and cats, some kill through ingestion, such as cane toads and others just compete to the point where there is no available food, such as rabbits in the early part of last century and crown of thorns stars more recently.

So what are the advantages and disadvantages of restricting ownership of reptiles to only native species?

Allowing only the keeping of native reptiles has allowed some degree of management of the trade and reduces significantly the number of wild caught animals. There is reduced demand for them and keepers can generally only get access through other licensed keepers or breeders. This should allow native populations to stabilise and grow. The extensive ball python trade had an impact on the ball python population in Africa, although this has been reduced in some parts such as Ghana with the creation of an export trade based on farm raised animals and regulated trading and capture and the increasing number available through breeders. Some parts of Africa are still not regulated and will probably see population crashes unless the trade is managed.

It also reduces the possibility of diseases being imported and spreading from wild caught animals from other countries. Many of the animals that are wild caught have parasites or diseases that can have a potentially devastating impact on native reptiles. The importation and sale of reptiles not properly quarantined, licensed or bred aggravates these risks. Likewise, illegal imports threaten local populations.

Another advantage is educating and enabling people to better appreciate their country’s native reptiles. Creating interest in reptiles unique to their country and their habitats should benefit the animals. Land clearance practices have led to the destruction or modification of large areas of native habitats in Australia. Australians also have a habit of killing snakes as there are, uniquely, more venomous than non-venomous snakes in Australia. Educating people about these animals, their role in the environment and the need to preserve them is vital to their long term viability in the wild.

Not allowing the keeping of alien or exotic reptiles reduces the possibility of these species escaping into the wild and causing damage to an already fragile eco-system. It is sound argument on the surface but any escapes would need to be in significant numbers to have any impact and would in fact have to be almost deliberate or from a large collection. For example a red-tailed boa escaping in Melbourne would not survive long in winter. Similarly, one escaping in Sydney would be hardly likely to meet another that perhaps escaped in Brisbane. Releasing several breeding pairs into the tropical rainforests of northern Queensland, however, would have vastly different effects. That would be a deliberate act of environmental vandalism. These acts do not need to be deliberate. The Red-eared Slider Turtle is cause for concern in parts of the world such as Malaysia where it is beginning to push native turtles from their habitat.

On the other hand, not having access to alien or exotic reptiles has its own implications.

Australia has not allowed native animals to be sold overseas for many years. This has led to issues of genetic diversity in some of the less available reptiles kept by overseas owners in the US, UK, Asia, South Africa and Europe. Some of these animals do not live as long and do not develop as well as they should. Allowing the sale of some animals, even in reduced numbers, would improve the genetic diversity and perhaps even improve the chances of the survival of some species through breeding efforts, such as has occurred already in Australia. It would, I believe, produce benefits for the animals and reptile owners around the world if it was managed in a sustainable and controlled way. It may even reduce the price of animals and relieve some of the illegal trade pressure.

It has created quite a flourishing illegal trade due to the scarcity and consequent high price that these animals command. The animals in turn suffer dreadfully. They are drugged and placed in suitcases, strapped to bodies and stuffed in all manner of containers with little or no ventilation in many cases. The death rate is often very high, but the price realised at the end justifies the high mortality. (there are many cases of people caught smuggling out of the country).

Allowing the keeping of alien or exotic reptiles also has some other advantages.

Our appreciation of exotic animals benefits by having access to them. Of course it should be managed so that wild caught animals are not traded excessively or to the point of being endangered and the available animals are free from disease and healthy. While international agreements are already in existence, these need to be adequately policed and monitored.

I personally don’t have an issue with people requiring a license to keep reptiles. The licensing should not be onerous, should be inexpensive, open to everyone and easy to get. It is really about making a statement. When you choose to keep certain types of reptiles it comes with a responsibility to both you and the animal. Having the licence means you understand that responsibility. As an example the license I have tells me what sort of animals I need a license for and what I don’t (not all require one). I also have to keep records of the animals I purchase, sell or those that die. It’s not a big deal and easy to do.

While this may be contentious I think it reinforces the idea that these animals do need special care and should be looked after in a responsible manner. There is a thriving trade in iguanas in the US but the numbers that die within a very short time of purchase is significant to the point of being unacceptable. Owners need to understand that an animal like that comes with a significant responsibility and has specific dietary and habitat requirements.

As one person wrote to me, expressing it better than I ever could:

“the S. Africa legislation taking place about "invasive" species …. puts a real damper on everyone's fun and hands-on education activities. I love the freedoms we experience here in the U.S. I can have virtually anything that I find of interest and can therefore learn about them and educate others about them. Without the ability to have first hand experience with these animals I doubt I would pursue these interests to the extent that I currently do and that would make for a very boring life - not to mention what a disservice it would be to the understanding and conservation of these animals with fewer people getting to experience how amazing the animals are.”

Overly strict regimes and regulations make it difficult for keen herpetologists and herp owners to legally keep and manage their collections, or in fact own any exotic reptile. While there is a need to manage our reptilian resources and provide the best outcomes for the animals concerned, both locally and internationally, this is not always achieved by draconian measures that take no account of responsible and experienced herp owners. Working cooperatively with the herp community to ensure realistic and enforceable laws and frameworks will produce a much more practical and achievable outcome that provides benefits and solutions for all stake holders.

Roaches on the march

"You lied"

These were the words that greeted me two days ago.

"You lied about the roaches!!!"

I didn't lie. I just didn't reveal the whole truth. I tried the roaches and "she who must be obeyed" found out. They are bloody fast. They are hard to dish out. And they escape. Occasionally. And they get found. Sometimes. In other parts of the house.

So I was in trouble.

But, and this is the real deal, they last for ages in dark postage tubes without food and water, you can manage to dish them out in small amounts into the lizard cage and the bearded dragon loves them.

I'm very impressed with these beasties. I sometimes dish out too many but you get so many for your money that a little over here and a little under there doesn't matter. And I don't have to do a damn thing to keep them. They're almost indestructible. Quite amazing really.

But, and this is the big drawback, the missus don't like 'em.

I can sort of understand her view. As a kid I was always taught that roaches were bad. Bad roaches, bad.

Well I'm a little older and a little more tranquil on the subject. They are just an insect. A very hardy insect, but, nonetheless, just an insect. So what's the fuss? I can't figure it out, but there is definitely a fuss.

So I'll just have to wear it down and convince her that the roaches are better reptile food because:
1. They are cheaper
2. They can be slowed down (gotta get my act into gear but need fridge permission)
3. They are yummy ( to bearded dragons anyway)
4. They last for a very, very long time with out food and water in a cardboard tube (unlike crickets - no need to replace the carrot)
5. They are easy to breed
6. They keep on growing for 360+ days

I think I might have to write an article on them for the newsletter as I now regard them as a viable alternative food source. I still use plenty of vegies, and in fact I am rather lucky because I have a number of dandelions growing in the front yard amongst the garden plants. I just chop the leaves up, add some celery leaves, a dash of spinach, maybe some lettuce, a bit of bok choi or whatever the green leaves of anything else such as broccoli leaves or cauliflower leaves.
