Q

What are the downsides of being an ectotherm?

A

More susceptible to stress
Suppressed immune system
Increased disease susceptibility
Relies on environment to maintain body temp
Larger the reptile=harder to heat up=loose heat faster

Q

What is Ecdysis?

A

Shed
New layer of epidermis skin
Lymph fluids diffuse between both layers
Enzymes create cleavage, splitting old skin
Soaking helps during shed to increase fluid for lymph production
Water can be absorbed from the cloaca
Snakes can shed in one peace

21
Q

Facts about amphibians?

A

Transitioned from aquatic fish to terrestrial animals
Completely separate from reptiles
Cold blooded
Ectotherms, hibernate, camo, everywhere but Antarctica
Must be near water, not salt
Too much sun and heat is lethal (desiccation)

22
Q

Metamorphosis?

A

All have this
Controlled by environment, DNA, hormones
Starts as aquatic eggs, dont have shells
Larvae have gills
Adults develope lungs
Some may never leave the larval stage

23
Q

Water (amphibians) ?

A

Adults breathe primarily through skin not lungs
Skin must stay moist
Use gloves, DI water, toxins

24
Q

Breathing (amphibians)?

A

Lungs poorly developed
No diaphragm or ribs, use mouth and throat to trap air
Nostrils used to remove CO2
Skin surface transmits O2 and CO2
AKA cutaneous respiration

25
Q

Eating (Amphibians)?

A

No teeth
Sticky tongue
Swallow prey whole
Some larvae are carnivorous
Most adults are carnivorous
Often need supplements
Over supplementation can be lethal

26
Q

Husbandry (amphibians)?

A

Mostly active during day, seasonal changes
Food size
Diff genders
Habitat style
Origin- captive/wild caught
Light
Humidity
Temp
Ventilation
Water quality
Proper cleaning

27
Q

Husbandry security (amphibians)?

A

Stress management
Visual, noise barriers
Escape prevention

28
Q

Temperate vs tropical vs desert

A

68-77
77-90
70-104

29
Q

Why do reptiles need POTZ?

A

Maintains metabolic activity, digestion, UVB utilization, reproduction

30
Q

Radiation?

A

Emission of energy in wave form (sunlight) (heat bulbs, SOME UVB bulbs)

31
Q

Conduction?

A

Heat directly transmitted (warm rocks) (heat pads, heat rocks)

32
Q

Convection?

A

Heat transferred through air or water (humidity) (environmental air)

33
Q

Thermogradient?

A

A range of temperatures or other factors an animals can choose within a cage, enclosure, or environment.

34
Q

What are the 3 types of light?

A

Heat
Visible light
UV
UVA
UVB
UVC

35
Q

UVA?

A

Visible to reptiles
Food
Behavioral choices
Stimulates endorphins/immune system

36
Q

UVB?

A

Synthesis of vitamin D3
Not visible
Cannot penetrate barriers
Oral over supplementations can be lethal
Can cause vitamin D toxicity from over oral supplementation
Calcifies organs
Fat soluble=harder to metabolize
MBD
Not enough

37
Q

When Calcium is involved….

A

So is phosphorus
Dietary Ca:P= 2:1
Proper feeding crucial
Gut load d=feeder animals

38
Q

UVC?

A

Not required and can be harmful
Used for sanitation purposes
Earths ozone layer filters this
Causes cancer and cataracts

39
Q

Snake handling?

A

Wash hand before
Don’t smell like food
Support entire body
A towel can be used for aggressive snakes
Never carry a constrictor around neck
Utilize one handler per 3-4 foot of snake
Use caution with giant constrictor
Venomous

40
Q

Tools for handling?

A

Snake hooks/tongs
Tubes
Snake bags
Buckets
Training classes
Shift cages for venomous snakes

41
Q

Handling lizards?

A

Wash hands before hand
Support all of body
Careful of tails
Use towel for aggressive
Never carry their mouth near your face
Crate train large lizards

42
Q

Tail autonomy?

A

Self amputation of tail
Iguanas, some geckos, some small skinks, tegus
Allow to escape
Disadvantage loss of energy reserves, huge demand to regrow
Regrowth is cartilage, new tail is NOT the same

43
Q

Handling crocs?

A

Few muscles to OPEN mouth
Secure head and jaws
Tail is powerful
Crate training is best

44
Q

Hearing?

A

Middle and inner ear only
Decent hearing
Tympanum=ear drum= lizards, frogs/toads, not snakes or salamanders
Crocs have external ear flaps

45
Q

Vision?

A

Snakes and SOME lizards have no eyelid
Have third eye= some lizards and amphibians
Poor eye muscles

46
Q

Taste?

A

Few taste buds
Some have no taste buds
Swallow prey whole

47
Q

Smell?

A

Excellent
Jacobsons organ
Chemoreceptor= senses heavier molecules like pheromones used for catching prey or mating
Very well developed in snakes

48
Q

Touch?

A

Crocs have ISO= integumentary sensory organ
Mechano receptors
Thermo receptors
Chemical receptors

49
Q

Sixth sense?

A

Electro-magnetic navigation
Sea turtles

50
Q

Enclosures need?

A

Proper UVB, heat, humidity, substrate, space
