Elephant, the largest terrestrial mammal, is a fascinating creature. Its size is enough to scare most animals away. But do you know what this  pachyderm is scared of? It’s mice. Well the fear has more to do with the element of surprise than mouse itself. This tiny creature nibbles at the mammoth’s feet or climbs up into its trunk, bringing great discomfort to elephant. Elephant’s tusks are modified incisors that grow throughout its life span. The animal uses its tusk to dig for salt, water and roots, to debark trees, to clear a path and fight. A fusion of its nose and upper lip, trunk is its most important limb. Using trunk an elephant can suck up to 14 litres of water at a time and blow it straight into its mouth!
