Reptile Facts Friday- Australia Edition

It’s Reptile Facts Friday!

We’re starting a new blog series here at the Reptile Zoo where we take 3 of our awesome animals and tell you a fun fact about them! This week, we’re highlighting our favorite Australian Lizards and their awesome defense systems!

Let’s start with one of the most charismatic reptiles out there, the bearded dragon! Beardies, as they’re called by enthusiasts, have one of the most obvious defense mechanisms of the lizard world. These little dudes are covered in big spikes all along their neck, cheek, and sides. Smaller spikes stand out from their legs, tail, and head.

Anything that wants to eat a bearded dragon has to think twice, as these guys are like the puffer fish of the lizard world. When feeling threatened, these guys will poof themselves up to almost double their usual body width. That lovely beard of spikes will inflate and turn black, and they will open their mouths and hiss. The overall effect is rather impressive, as you can see.

Our next Aussie is slightly more subtle but no less awesome. The blue tongued skink gets its name from its main form of defense! These cool lizards have a tongue that is, you guessed it, blue!

When feeling threatened, the skink will puff itself up, hiss, and show off its bright blue tongue. Bright colors in the animal kingdom generally mean that the animal with them is poisonous. While the blue tongued skink doesn’t actually have poison or venom, their attacker will usually fall for the trick and leave them alone.

If that display doesn’t work, their hard thick scales can protect them from bites. They’re capable of running surprisingly fast for their tiny legs, and can drop their tails at will to distract a predator. Most of the time their snake-like appearance is enough to make anybody think twice about touching them.

The last and possibly most bizarre Australian lizard is the Frill-Necked Lizard, or Frilled Dragon. These little guys get their name from the large flap of extra skin attached to their jawline. The frill is usually kept close to the body and out of the way to prevent damage, giving them a slightly wrinkly appearance.

When threatened, the lizard opens their mouth and extends their frill, showing off the bright colored spots usually hidden in the folds of skin. This rapid increase in perceived size is enough to frighten any predator, but the lizard doesn’t stop there. They will hiss, stand on their hind legs using their tail for balance, and even chase after their attackers to make good and sure they don’t get messed with.

So there you have it! Three Australian lizards with three awesome defenses! That’s all for Reptile Facts Friday this week!

When I first got married I worked in the city; planning for dinner wouldn't start until I was getting off the bus at 6:30 at night. If you know that this personalized gift is expensive you will need to start saving early. It holds not even 2 ounces of water, but is useful for steaming an outfit in the morning.

Interims of the actual structure and parts and such of a paintball gun, there are 4 major and one ultra major part of the gun. But the main difference between cheap paintball guns and expensive ones is that the latter are just made to last longer. A cheap paintball gun is built using durable material which provides good quality.

The primary disadvantage of this system is its all round high quality. "Making coffee," these days, has been reduced to simply setting a timer and pushing a button. Then we heard about the Keurig Coffee maker from a friend.

Just don’t get carried away with supplies, you should only have enough that you can carry without getting tired while walking. Perhaps the phrase could mean something like a far distance. Natural history specimens are used for school loan services, and provide a range of specimens for identification in biology examinations at all levels.

This fencing needs to be properly installed and should not leave gaps under the fence or at the sides. The idea is that instead of climbing up on a ladder, the blower hoses out the leaves, then you just rake them up (or not, depending on how dirty your gutters were). t have to wear shirts or shoes, and you get to play with explosives.

Carl tells Rick about what Carol is doing, and Rick seems to care less. All that they did was use their mind to gain muscle. You can't however always predict who, what, where, when, and why a specific target will be chosen.

Cook a meal by simply adding some cooked meat or vegetables and seasoning to your rice. (You may have to have to alter the seasonings again also. If you have a bamboo mat, use it to make sure the roll has equal pressure applied on it and is packed tightly.

Marketing: Use notebook skin, for your marketing purpose. AMD's new Fusion APUs are the first new netbook processors to hit since Atom, and they could change the entire netbook market. However, most people (including myself) peg their best uses as gaming and business.
