A: Herpetology.

In addition to the living reptiles, there are many diverse groups that are now extinct, in some cases due to what?
A: Mass extinction events.


Modern non-bird reptiles inhabit all the continents except what?
A: Antarctica.

Reptiles are tetrapod vertebrates, creatures that either have four limbs or, like snakes, are what?
A: Descended from four-limbed ancestors.

A: The steaming swamps of the late Carboniferous period, when the first reptiles evolved from advanced

As in all animals, reptilian muscle action produces what?
A: Heat.


In large reptiles, like leatherback turtles, the low surface-to-volume ratio allows this metabolically produced heat to do what?

A crocodile needs from a tenth to a fifth of the food necessary for a lion of the same weight and can live how long without eating?
A: Half a year.

Lower food requirements and adaptive metabolisms allow reptiles to dominate the animal life in what type of regions?

Most extant reptiles are carnivores with what feeding strategy?
A: A sit-and-wait.

All reptiles breathe using what?
A: Lungs.


Aquatic turtles have developed what?
A: More permeable skin, and some species have modified their cloaca to increase the area for gas exchange.

Most reptiles lack a secondary palate, meaning that they must do what?
A: Hold their breath while swallowing.

Crocodilians have evolved a bony secondary palate that allows them to continue breathing while what?

Compared with frogs, birds, and mammals, reptiles are less what?
A: Vocal.

Sound production is usually limited to what?
A: Hissing, which is produced merely by forcing air though a partly closed glottis and is not considered to be a true vocalization.

The ability to vocalize exists in crocodilians, some lizards and turtles; and typically involves what?
A: Vibrating fold-like structures in the larynx or glottis.

Some geckos and turtles possess true vocal cords, which have what?
A: Elastin-rich connective tissue.

Unlike humans and other animals, snakes do not possess what?
A: An outer ear, a middle ear, and a tympanum but have an inner ear structure with cochleas directly connected to their jawbone.


They are able to feel the vibrations generated from the sound waves in their jaw as they do what?
A: Move on the ground.

This is done by the use of mechanoreceptors, sensory nerves that run where?
A: Along the body of snakes directing the vibrations along the spinal nerves to the brain.

Snakes have a sensitive auditory perception and can tell what?
A: Which direction sound being made is coming from so that they can sense the presence of prey or predator.

Reptilian skin is covered in a horny epidermis, making it watertight and enabling reptiles to live on what?
A: Dry land, in contrast to amphibians.

Compared to mammalian skin, that of reptiles is rather thin and lacks the thick dermal layer that does what?
A: Produces leather in mammals.


Exposed parts of reptiles are protected by what?
A: Scales or scutes, sometimes with a bony base (osteoderms), forming armor.

 In lepidosaurians, such as lizards and snakes, the whole skin is covered in what?
A: Overlapping epidermal scales.

The scales found in turtles and crocodiles are of dermal, rather than epidermal, origin and are properly termed what?
A: Scutes.

In turtles, the body is hidden inside a hard shell composed of what?
A: Fused scutes.

Lacking a thick dermis, reptilian leather is not what?
A: As strong as mammalian leather.


It is used in leather-wares for what?
A: Decorative purposes for shoes, belts and handbags, particularly crocodile skin.

Reptiles shed their skin through a process called what?
A: Ecdysis which occurs continuously throughout their lifetime.

 In particular, younger reptiles tend to shed once every how often?
A:  5–6 weeks while adults shed 3–4 times a year.

Younger reptiles shed more because of what?
A: Their rapid growth rate.

The process of ecdysis involves forming what?
A: A new layer of skin under the old one.

 Proteolytic enzymes and lymphatic fluid is secreted where?
A: Between the old and new layers of skin.

Consequently, this lifts the old skin from the new one allowing what?
A: Shedding to occur.

 Snakes will shed from the head to the tail while lizards shed how?
A: In a "patchy pattern".
