Today, pet.net will introduce the physiological characteristics of rabbit.

①Ears: The ears of rabbits can rotate freely, hear very small sounds, and the blood vessels are very dense. Because the sweat glands on the outside of the rabbit's body are not developed, the heat is dissipated from the body through the blood vessels on the ears.

②Eyes: The eyes are located on both sides of the face, so the visual field is close to 300 degrees, but rabbits are nocturnal animals and have poor ability to see things during the day.

③ Nose and beard: The nose of a rabbit is always moving, which is one of the characteristics. Since the nose is very sensitive to smells, it can distinguish very subtle smells. Because it is a nocturnal animal, the beard plays a role in detecting objects around it.

④ Mouth: The mouth that has been chewing is connected from the upper lip to the nostrils, which is very suitable for chewing with the front teeth. There are sweat glands under the chin that secrete body odor, so I find rabbits often rub their necks against objects around them to demarcate their territory.

⑤ Teeth: The upper incisors are double-layered, with two sharper front teeth and two smaller rear ones, with a total of 28 teeth. The upper and lower incisors grow throughout their lives, so rabbits keep gnawing to adjust the length of the teeth.

⑥ Hair: The soft hair on the whole body has a thermal insulation effect, which can reduce the penetration of water.

⑦Forelimbs: The forelimbs are shorter than the hindlimbs and are very suitable for activities on flat ground and up and down slopes. There are 5 toes, and the nails are very sharp, suitable for digging holes.

⑧ Hind limbs: The hind limbs are longer and stronger than the front limbs, and can jump very high. There are 4 toes, and the soles of the feet are not padded, but covered with hair.

⑨Anus: There are also sweat glands near the anus, which can secrete a unique smell and leave their own traces. Using this smell, you can distinguish each other's age and gender.

⑩ Tail: The tail is covered with soft fur. The color inside the tail is generally red or light. When it encounters danger, it will stand up and reveal a red warning color to inform the same kind.
