How Smart Are You With Animals?

The answer is "Eye" because an ostrich's eye is bigger than its brain. Ostriches have the largest eyes of any land animal, measuring about 2 inches in diameter. In contrast, an ostrich's brain is relatively small, weighing only a few grams. This is a unique characteristic of ostriches and is necessary for their survival in their natural habitat.

Sharks do not have bones in their bodies. Instead, they have a cartilaginous skeleton which is made up of flexible cartilage rather than hard bones. Therefore, the correct answer is "None" as there are no bones in a shark's body.

Cats have 32 muscles in each ear. These muscles allow cats to move their ears independently, enabling them to accurately locate sounds and detect prey or potential threats. The large number of muscles in their ears gives cats exceptional hearing abilities and helps them to be highly alert and responsive to their environment.

Snails have the ability to enter a state of torpor, which is similar to hibernation. During this time, their metabolic rate decreases significantly, allowing them to conserve energy. This torpor state can last for several years, during which the snail remains inactive and does not require food or water. Therefore, the correct answer is "Three years."

Cockroaches have an open circulatory system, which means they do not rely on their heads to pump blood. They have small openings called spiracles on their body segments that allow them to breathe. Therefore, even without a head, a cockroach can still breathe and survive for a few weeks. However, without a head, they are unable to eat or drink, so they eventually die due to dehydration or starvation.

Chickens are not known for their flying abilities, as they have short wings and heavy bodies. However, in rare cases, chickens can manage to fly for short distances. The longest recorded flight of a chicken is 13 seconds, which is longer than the other given options. This suggests that while chickens are not natural fliers, they can still achieve brief moments of flight under certain circumstances.

A mole can dig a tunnel of approximately 90 meters in one night. Moles are known for their exceptional digging abilities, with strong front limbs and sharp claws. They can tunnel through soil at an impressive speed, creating intricate networks of underground passages. While the exact distance a mole can dig in one night may vary depending on factors such as soil type and mole species, 90 meters is a reasonable estimate based on their typical capabilities.

Donkeys have eyes positioned on the sides of their head, allowing them to have a wide field of vision. This enables them to see all four of their feet at once.

Hedgehogs have a relatively high heart rate compared to other animals. The average heart rate for a hedgehog is around 300 beats per minute. This is due to their small size and fast metabolism, which requires a higher heart rate to pump oxygen and nutrients throughout their bodies efficiently.

Slugs do not have noses in the traditional sense. They have sensory organs called tentacles, which they use to detect their environment. Slugs typically have two pairs of tentacles, with the upper pair being longer and used for sensing light and movement, while the lower pair is used for detecting chemicals in their surroundings. Therefore, the correct answer is 4, as slugs have four tentacles in total.
