Physiognomy : Camelus dromedarius
Camels have broad, flat, leathery pads with two toes on each foot which distribute the camels weight, preventing the foot from sinking into the sand. They walk at around 5 kmh and can gallop at 20 kmh.
Camels are adapted to hot, arid conditions. They do not pant and can raise their body temperature as high as 40.5°C to avoid perspiring and losing fluid. Their ears are lined with fur and their eyes have a double row of long curly eyelashes to protect against desert sand.
