Which form of locomotion do the fastest terrestrial snakes use?

	Climbing
	Lateral undulation
	Concertina
	Rectilinear crawling
	Sidewinding
Please select an option Incorrect Arboreal snakes use several modes of locomotion on trees depending on species and bark texture. They do not move fastest on branches however. WikiVet Article: Snake Locomotion. Correct! Lateral undulation is the type of locomotion usually associated with snakes i.e. side to side wriggling. The fastest terrestrial snakes use this method of locomotion WikiVet Article: Snake Locomotion. Incorrect This is common in burrowing snakes and can be seen when a snake crawls through a tube. It is common in arboreal and fossorial snakes, and requires the most energy. WikiVet Article: Snake Locomotion. Incorrect This is the slowest type of locomotion. The edges of the scales act as anchor points and the muscles then pull the body up to that point. This is often used by large snakes. WikiVet Article: Snake Locomotion. Incorrect This is similar to concertina locomotion but the angle of movement is at 45 degrees to the direction that the snake is pointing. WikiVet Article: Snake Locomotion.

Which is the preferred optimum temperature zone for Garter snakes?

	14 - 22°C
	21 - 32°C
	25 - 32°C
	25 - 34°C
	28 - 34°C
Please select an option Incorrect Snakes are ectothermic vertebrates that regulate body temperature by behavioural and physiological processes. Optimum functioning of metabolic processes, including digestion, growth, healing, reproduction and immune system is reliant on temperature. Wikivet Article: POTZ. Correct! Garter snakes require a daytime temperature of about 25° to 30°C falling at night to 24° 26°C. A temperature drop for up to three months between November and February stimulates reproduction. WikiVet Article: Garter snake. Incorrect This is the POTZ for a common kingsnake or corn/rat snake. WikiVet Article: Kingsnake and Corn snake. Incorrect This is the POTZ for a Burmese python WikiVet Article: Burmese python. Incorrect This is the POTZ for the Boa constrictor WikiVet Article: Boa constrictor.
