1.
What type of environment is most suitable for centipedes?
Correct Answer
B. Moist environment
Explanation
Centipedes are arthropods that require a moist environment to survive. They have a thin exoskeleton that is prone to drying out, so they thrive in areas with high humidity and moisture. This type of environment provides the necessary conditions for centipedes to find shelter, hunt for prey, and reproduce effectively. A moist environment also helps them to regulate their body temperature and prevent dehydration. Therefore, a moist environment is the most suitable for centipedes to thrive.
2.
Which of these is not a specie of centipedes?
Correct Answer
C. Centruroides exilicauda
Explanation
Centruroides exilicauda is not a species of centipede. Scutigera coleoptrata, Scolopendra gigantea, and Scolopendra subspinipes are all known species of centipedes. However, Centruroides exilicauda is actually a species of scorpion, not a centipede.
3.
What do giant centipedes prey on?
Correct Answer
D. All of these
Explanation
Giant centipedes are known to be voracious predators and have a wide-ranging diet. They are capable of preying on small rodents, such as mice and rats, due to their size and venomous bite. They also feed on roaches, which are a common food source for them. Additionally, although less common, there have been instances where giant centipedes have been observed capturing and feeding on bats. Therefore, the correct answer is that giant centipedes prey on all of these creatures.
4.
Which of these creatures prey on centipedes?
Correct Answer
D. All of these
Explanation
All of these creatures prey on centipedes. Snakes are known to feed on centipedes as part of their diet. Mongooses are also known to prey on centipedes, as they are skilled hunters and can catch and consume them. Salamanders, although not as commonly known for preying on centipedes, have been observed to feed on them as well. Therefore, all of these creatures can be considered predators of centipedes.
5.
Which is the largest centipede in the world?
Correct Answer
A. Amazonian giant centipede (Scolopendra gigantea)
Explanation
The Amazonian giant centipede (Scolopendra gigantea) is the largest centipede in the world. It can reach lengths of up to 12 inches and has a venomous bite. This centipede is found in the rainforests of South America and is known for its aggressive behavior and ability to prey on a variety of animals, including mice and bats. Its large size and potent venom make it a formidable predator in its habitat.
6.
Centipedes inject venom into their prey through their:
Correct Answer
C. Fangs
Explanation
Centipedes inject venom into their prey through their fangs. These fangs are specialized appendages located in the front of their head. When a centipede catches its prey, it uses its fangs to deliver venom, which helps to immobilize or kill the prey. The venom also aids in breaking down the prey's tissues, making it easier for the centipede to consume.
7.
How do centipedes obtain oxygen?
Correct Answer
D. Through holes in their bodies
Explanation
Centipedes obtain oxygen through holes in their bodies. Unlike insects, centipedes do not have specialized respiratory organs such as lungs or tracheae. Instead, they have small openings called spiracles along the sides of their body segments. These spiracles allow air to enter and diffuse oxygen into their tissues. This method of respiration is known as "diffusion respiration" and is common among many arthropods that lack dedicated respiratory structures.
8.
Which of these abilities do centipedes have?
Correct Answer
B. Centipedes can regrow their limbs.
Explanation
Centipedes have the ability to regrow their limbs. This is a unique characteristic of centipedes, as most other creatures cannot regenerate lost body parts. This ability allows centipedes to recover from injuries and continue their normal activities. It is an important adaptation that helps them survive in their environment and maintain their locomotion and hunting abilities.
9.
Centipedes can be found in
Correct Answer
D. All of the above
Explanation
Centipedes can be found in forests, savannahs, and deserts. They are adaptable creatures that can survive in various habitats. Forests provide them with a moist environment and plenty of leaf litter for hiding and hunting. Savannahs offer open grasslands where they can easily move and hunt for prey. In deserts, centipedes have adapted to the arid conditions by burrowing into the sand and seeking shelter during the day. Therefore, the correct answer is "All of the above" as centipedes can be found in all of these habitats.
10.
What do centipedes use to locate their prey?
Correct Answer
A. Antennae
Explanation
Centipedes use their antennae to locate their prey. These long, segmented appendages are highly sensitive to touch and can detect vibrations in the environment. By waving their antennae in the air, centipedes can pick up on the movements and presence of potential prey nearby. This allows them to accurately locate and capture their food. Fangs, tongue, and abdomen do not play a role in prey location for centipedes.
