There were several elephants in this spot near the road. We watched in amazement.
Ears and eyes
African bush elephant with ears spread in a threat or attentive position; note the visible blood vessels Elephant ear flaps, or pinnae, are 1–2 mm (0.039–0.079 in) thick in the middle with a thinner tip and supported by a thicker base. They contain numerous blood vessels called capillaries. Warm blood flows into the capillaries, releasing excess heat into the environment. This effect is increased by flapping the ears back and forth. Larger ear surfaces contain more capillaries, and more heat can be released. Of all the elephants, African bush elephants live in the hottest climates and have the largest ear flaps.The ossicles are adapted for hearing low frequencies, being most sensitive at 1 kHz.
Lacking a lacrimal apparatus (tear duct), the eye relies on the harderian gland in the orbit to keep it moist. A durable nictitating membrane shields the globe. The animal's field of vision is compromised by the location and limited mobility of the eyes. Elephants are dichromats and they can see well in dim light but not in bright light.
An amazing experience!
