Question 1

Another name for mandibular bone degeneration is _____.&#10;A)red chops&#10;B)snap and gulp&#10;C)soft jowl&#10;D)rubber jaw

Accepted Answer

Mandibular bone degeneration is commonly referred to as "rubber jaw."

Question 2

Chytridiomycosis is _____.&#10;A)caused by consuming too many mealworms&#10;B)a fungal skin disease&#10;C)a bacterial infection of the GI tract&#10;D)caused by inadequate UV lighting

Accepted Answer

Chytridiomycosis is a fungal disease that affects amphibians, causing skin thickening and eventually death. It is caused by the chytrid fungus.

Question 3

Poison dart frogs _____.&#10;A)should never be kept in captivity&#10;B)lose their bright colors when kept in captivity&#10;C)can be detoxified by soaking them in a base solution&#10;D)derive toxins from feeding on ants that eat toxic plants

Accepted Answer

Poison dart frogs do not produce their own toxins, but instead, they accumulate toxins by feeding on ants that ingest poisonous plants. In captivity, they can still maintain their bright colors if properly cared for, and they do not need to be detoxified as they will not produce toxins without access to their natural diet.

Question 4

All amphibians are poikilotherms; that is, they are totally dependent on to regulate body temperature and metabolic activity.&#10;A)a proper diet&#10;B)adequate oxygen&#10;C)other amphibians&#10;D)their environment

Accepted Answer

Amphibians are dependent on their environment to regulate their body temperature and metabolic activity. They cannot regulate their own temperature like endothermic animals (e.g. mammals and birds) can. Therefore, the external temperature and availability of heat sources (e.g. sunlight) in their environment directly affect their bodily functions.

Question 5

Anesthesia in amphibians is similar to anesthesia.&#10;A)fish&#10;B)reptile&#10;C)rodent&#10;D)small mammal

Accepted Answer

Amphibians and fish share similar physiological characteristics, making their anesthesia protocols more comparable than with reptiles, rodents, or small mammals.

Question 6

All adult amphibians eat _____.&#10;A)algae and water plants&#10;B)an omnivorous diet&#10;C)only live food&#10;D)carrion

Accepted Answer

Adult amphibians are carnivores and only eat live food such as insects, snails, and worms.

Question 7

Diurnal amphibians need _____.&#10;A)full spectrum lighting&#10;B)bulbs that produce black light&#10;C)bulbs that produce red light&#10;D)very little artificial light

Accepted Answer

Diurnal amphibians require full spectrum lighting to mimic natural sunlight and support their natural behaviors and health. Black light and red light are not suitable for providing the necessary light spectrum for diurnal amphibians, and very little or no artificial lighting may not provide enough light for their needs.

Question 8

Today, there are different species of amphibians.&#10;A)approximately 100,000&#10;B)more than 4,000&#10;C)no more than 200&#10;D)roughly 30,000

Accepted Answer

According to current estimates, there are more than 4,000 species of amphibians.

Question 9

Healthy amphibian skin is _____.&#10;A)shed regularly&#10;B)tacky and dark&#10;C)not shed&#10;D)shed in patches

Accepted Answer

Healthy amphibian skin sheds regularly to remove old skin cells and maintain its permeability for gas exchange and hydration. A tacky and dark appearance can sometimes indicate a fungal infection or other health issues, while not shedding or shedding in patches can be signs of underlying health problems.

Question 10

The humidity necessary for amphibians is _____.&#10;A)no less than 95 percent&#10;B)never greater than 80 percent&#10;C)usually 75 to 90 percent&#10;D)between 45 and 70 percent

Accepted Answer

Amphibians require a humid environment, but the humidity levels depend on the species of amphibian. Generally, the humidity necessary for amphibians is usually 75 to 90 percent. This allows them to maintain their water balance and keep their skin moist. Humidity levels that are too low or too high can lead to health problems for amphibians. Therefore, option C is the best choice.
