What species of Passerine bird is this?

	Swallow (Hirundo rustica)
	House Martin (Delichon urbica)
	Pied Wagtail (Motacilla alba)
	Swift (Apus apus)
	Starling (Sturnus vulgaris)
Please select an option Incorrect! This species is called a House Martin, with its pure white underparts as well as a white rump and short forked tail. Although they belong to the same family, swallows have distinctive red throats and long tail streamers. They are extremely agile in flight and spend most of their time on the wing. WikiVet Article: Lizard Eye. Correct! This species is called a House Martin, with its pure white underparts as well as a white rump and short forked tail. The bird's mud nest is usually sited below the eaves of buildings. They are summer migrants and spend their winters in Africa. Although still numerous and widespread, recent moderate declines earn them a place on the Amber List. WikiVet Article: Lizard Eye. Incorrect. This species is called a House Martin, with its pure white underparts as well as a white rump and short forked tail. Pied Wagtails also have a black and white plumage, but they possess a black beak, have long slender legs, with long hindclaws and a long-rectangular tail that they characteristically are frequently “wagging”. WikiVet Article: Lizard Eye. Incorrect. This species is called a House Martin, with its pure white underparts as well as a white rump and short forked tail. Swifts are larger birds with a dark underside, long, scythe-like wings and a short, forked tail. Like the House Martins and Swallows, it is also a Summer migrant and spends its winters in Africa. WikiVet Article: Lizard Eye. Incorrect. This species is called a House Martin, with its pure white underparts as well as a white rump and short forked tail. Starlings are bigger birds with long legs and although its adult plumage may seem black in the distance, it is actually very glossy with a sheen of purples and greens. Unlike swifts, swallows and house-martins they walk and run confidently on the ground. WikiVet Article: Lizard Eye.

Injecting lizards with nephrotoxic drugs could potentially result in increased renal toxicity because...?

	lizards have a three chambered heart.
	the venous return from the tail and hindlimbs isn't filtered through the kidneys.
	reptiles are extremely sensitive to nephrotoxic drugs.
	the venous return from the tail and hindlimbs isn't filtered through the liver.
	of the renal portal system
Please select an option Incorrect! Lizards do indeed have a three chambered heart; however this does not explain the increased renal toxicity. The reason is that reptiles have a renal portal system where venous return from the tail and hindlimbs may be filtered through the kidneys to bathe the renal tubules. Therefore the injection of drugs that are cleared via tubular excretion into the caudal half of the body could result in lower than anticipated serum concentration because of their excretion in the urine before entering the systemic circulation. WikiVet Article: Lizard Cardiovascular System Incorrect! Reptiles have a renal portal system where venous return from the tail and hindlimbs may be filtered through the kidneys to bathe the renal tubules.

WikiVet Article: Lizard Cardiovascular System Correct! Reptiles have a renal portal system where venous return from the tail and hindlimbs may be filtered through the kidneys to bathe the renal tubules. Venous return may also be filtered through the liver. Therefore the injection of drugs that are cleared via tubular excretion into the caudal half of the body could result in lower than anticipated serum concentration because of their excretion in the urine before entering the systemic circulation.WikiVet Article: Lizard Cardiovascular System

What anatomical characteristic is specific to lizards capable of autotomy?

	They have a horizontal fracture plane through the body.
	They lack part of the neural arch of the tail vertebrae.
	They have a vertical fracture plane through the body.
	They have a single occiptal condyle.
	They have ribs on tail and cervical vertebrae.
Please select an option Incorrect! Lizards that are capable of autotomy have a vertical fracture plane through the body and part of the neural arch of the tail vertebrae. WikiVet Article: Lizard Musculoskeletal System. Incorrect! Lizards that are capable of autotomy have a vertical fracture plane through the body and part of the neural arch of the tail vertebrae. WikiVet Article: Lizard Musculoskeletal System. Correct! Lizards that are capable of autotomy have a vertical fracture plane through the body and part of the neural arch of the tail vertebrae. WikiVet Article: Lizard Musculoskeletal System. Incorrect! Like other reptiles, lizards have a single occiptal condyle. This characteristic isn't specific to lizards capabale of autotomy. WikiVet Article: Lizard Musculoskeletal System. Incorrect! Ribs are present on all vertebrae except tail and cervical vertebrae. WikiVet Article: Lizard Musculoskeletal System.

In lizards, what is the proctodeum?

	The part of the cloaca which collects urinary wastage.
	The final chamber of the cloaca, prior to elimination.
	The part of the cloaca which collects faeces.
	The equivalent of a caecum in mammals.
	The name given to the transverse cloacal slit.
Please select an option Incorrect! The ureodeum is the part of the cloaca which collects urinary wastage. WikiVet Article: Lizard Gastrointestinal System Correct! The proctodeum is the final chamber of the cloaca, prior to elimination. WikiVet Article: Lizard Gastrointestinal System Incorrect! The coprodeum is the part of cloaca which collects faeces. WikiVet Article: Lizard Gastrointestinal System Incorrect! A caecum is present in many lizard species. WikiVet Article: Lizard Gastrointestinal System Incorrect! The vent is the external opening of the cloaca. The proctodeum is the final chamber of the cloaca, prior to elimination. WikiVet Article: Lizard Gastrointestinal System
