All animal rights activists may rest assured; we do not intend to fit valves from our factory to elephants in the future. Elephants do not need them anyway.
Their trunk is a multifunctional organ: for feeling, gripping, breathing, smelling and fighting. The trunk is also used as a suction and pressure pump thus allowing the elephant to drink 200 litres of water in 5 minutes. The trunk can also be used to spread dirt and dust over the skin. No matter whether it's regulating or controlling, water or highly viscous media, the elephant and nieruf can cope it.
