Which snake doesn't have to have a mate to lay eggs?
Correct Answer
D. Flower pot snake
Explanation
The flower pot snake, also known as the Brahminy blind snake, is a unique species that can reproduce through a process called parthenogenesis. This means females can produce fertile eggs without mating, resulting in offspring that are genetically identical to the mother. This adaptation allows them to colonize new areas effectively, even when males are scarce.
2.
Which snake is the longest?
Correct Answer
B. Reticulated python
Explanation
The reticulated python is the longest snake in the world. It can grow up to 30 feet in length, making it longer than the green anaconda and king cobra. Therefore, the correct answer is reticulated python.
3.
Which snake can sense light with its tail?
Correct Answer
B. Olive sea snake
Explanation
The olive sea snake is the correct answer because it has a specialized organ called the "photoreceptive tubercles" located on its tail. These tubercles contain light-sensitive cells that allow the snake to perceive and respond to changes in light levels. This adaptation helps the olive sea snake navigate and hunt effectively in its marine environment.
4.
Which of these snakes is non-venomous?
Correct Answer
C. Python
Explanation
The python is a non-venomous snake. Unlike the cottonmouth, taipan, and black mamba, which are all venomous snakes, the python kills its prey by constriction rather than injecting venom. Therefore, the python is the correct answer as the non-venomous snake in this question.
5.
What do snakes not have?
Correct Answer
B. Eyelids
Explanation
Snakes do not have eyelids. Unlike humans and many other animals, snakes do not have movable eyelids to protect their eyes. Instead, they have a transparent scale called a spectacle or brille that covers and protects their eyes. This scale does not blink or close like eyelids do, allowing snakes to keep their eyes open at all times, even when they are sleeping or shedding their skin. This adaptation helps snakes to detect movement and potential threats in their environment.
6.
Which of these snakes does not lay eggs?
Correct Answer
A. Gaboon viper
Explanation
The Gaboon viper is ovoviviparous, meaning it gives birth to live young that develop inside eggs retained within the mother's body. This reproductive strategy is advantageous in cooler climates or unpredictable environments as it allows the mother to regulate the temperature and development of her offspring, increasing their chances of survival. In contrast, timber rattlesnakes and ball pythons lay eggs externally and rely on suitable environmental conditions for incubation.
7.
What do snakes smell with?
Correct Answer
A. Tongue
Explanation
Snakes use their tongues to smell. They have a specialized organ called the Jacobson's organ located on the roof of their mouth, which allows them to pick up scent particles in the air. When a snake flicks its tongue out, it collects these particles, and then inserts its tongue into the Jacobson's organ to analyze the scents. This helps snakes to locate prey, navigate their environment, and communicate with other snakes. Therefore, the correct answer is "Tongue".
8.
Which snake has the longest fangs?
Correct Answer
D. Gaboon viper
Explanation
The Gaboon viper has the longest fangs among the given options. These venomous snakes are known for their exceptionally long fangs, which can reach up to two inches in length. The length of their fangs allows them to deliver a deep bite and inject a substantial amount of venom into their prey or potential threats. This makes the Gaboon viper one of the most dangerous snakes in Africa.
