Snakes Flashcards
Who has vestigial pelvis
Boids
Snakes ears
No external ear but has an inner ear
Attuned to low frequency sounds and vibration
Labial pits
Heat sensing organ on upper and lower lip
Act like thermal cameras more than feeling
Vomeronasal organ
Flick their tongue and used for chemosensation
Normal ecdysis
Shedding of skins every 3-4 months as adults
Growing exerts pressure on cells and causes the skin to crack open from front to back
Eyelids
Dont have eyelid and have a translucent scale over cornea
Common causes of spectacle dysecdysis
Lack of humidity-> rigidity to shed skin and becomes brittle and not detach in a single flexible piece
Lack of hydration-> prevents adequate lymph volume to fully hydrate epidermal tissue from between the tissue layers
Lack of furniture edge to rub against
Treatment of spectacle dysecdysis
Correct husbandry issues
Correct dehydration
Soak in water or hydrogel and remove spectacle (if husbandry not an issue)
Snake mites
Survive in environment for a long time and hatch in 2 days that live in substrate
Protonymphs are the most aggressive
Clinical signs of mites
Dyscedysis
Excessive bathing
Erratic body movements
Eye discharge/crusting
Black spots on scales and around eyes
Weakness, lethargy from anemia
Diagnosis of mites
See them on the snake is definitive usually around eye margins, around the cloaca, and under ventral scales
Treatment of mites
Isolate and aggressive decontamination of environment
Dilute iodine with mechanical removal
Ivermectin SQ
Pre-ovulatory stasis
Failure to ovulate
Hormonal insufficiency, metabolic deficiency, infundibulum damage or defect
Post ovulatory stasis
Hormonal insufficiency
Ca deficiency
Salpinx inertia
Obstructive disease
Infectious injury to repro tract
Most common in snakes
Clinical signs of ovulatory stasis
-Straining to pass eggs
-Malaise, lethargy
-Reduced appetite
-Flaccid body position if severe
-Caudal coelomic swelling
-Cloacal discharge
-History of normal egg schedule not accomplished
