What Do You Know About The Hedgehog?

Explanation
There are 16 species of hedgehogs.

Explanation
Hedgehogs typically have a lifespan of 3-5 years. This means that on average, hedgehogs can live for up to 5 years, but some may only live for 3 years. Factors such as diet, habitat, and overall health can influence the lifespan of a hedgehog. It is important for hedgehog owners to provide proper care and nutrition to ensure their pet's longevity.

Explanation
During hibernation, hedgehogs experience a significant drop in their body temperature to conserve energy. This decrease in body temperature helps them enter a state of torpor, where their metabolic rate slows down, and they become inactive. A body temperature of 2°C is extremely low but allows hedgehogs to survive the winter months with minimal energy expenditure. At this temperature, their heart rate and breathing slow down, and they rely on stored fat reserves to sustain themselves until warmer temperatures return.

Explanation
Hedgehogs have a normal temperature range of 30-35°C. This temperature range is suitable for their physiological processes and overall well-being. It is important to maintain this temperature range in their habitat to ensure their comfort and health. Temperatures outside of this range can lead to stress, illness, or even death in hedgehogs.

Explanation
Hedgehogs primarily feed on insects. They have a diverse diet that includes beetles, caterpillars, slugs, snails, and other small invertebrates. Insects provide hedgehogs with necessary nutrients and protein for their growth and survival. While hedgehogs may also consume other food items like fruits, vegetables, and small vertebrates, insects are their major source of sustenance.

Explanation
The exoskeleton of hedgehogs is made up of spines. These spines are modified hairs that are stiff and sharp, providing protection for the hedgehog's body. The spines are attached to the hedgehog's skin and can be raised or lowered depending on the hedgehog's need for defense. The spines act as a barrier against predators, helping to keep the hedgehog safe from harm.

Explanation
Hedgehogs have a poor sense of eyesight. While they have excellent hearing and smell, their eyesight is not as developed. Hedgehogs primarily rely on their other senses to navigate their surroundings and find food. Their eyesight is generally considered to be weak, and they are more active during the night when their other senses are more effective.

Explanation
Hedgehogs have about 5000 spines. These spines are actually modified hairs that cover their backs and sides, providing protection against predators. The spines are hollow and made of keratin, the same material found in human hair and nails. When a hedgehog feels threatened, it rolls into a tight ball, causing the spines to stick out in all directions, making it difficult for predators to attack. The large number of spines ensures that the hedgehog is well protected and can effectively defend itself.

Explanation
The Arctic fox is not a predator of hedgehogs. While ferrets, owls, and mongooses are known to prey on hedgehogs, the Arctic fox does not typically feed on them. This could be due to the fact that hedgehogs are not native to the Arctic region where the foxes reside, or because hedgehogs may not be a suitable prey for the Arctic fox's hunting strategy or diet.

Explanation
Baby hedgehogs typically open their eyes around 2-3 weeks after birth. This is an important developmental milestone for them as it allows them to explore their surroundings and become more independent. Therefore, the correct answer is 3 weeks.
