Giraffe and acacia

Browsing giraffes are a common sight on any safari as they love the tender leaves and twigs of acacia trees. Since a giraffe eats up to 34 kilograms every day in order to sustain its bulk, acacias have developed clever defence mechanisms to avoid being stripped completely. Apart from their big thorns – that can be negotiated by the giraffe’s flexible upper lip and prehensile tongue – acacias charge their leaves with alkaloids, chemical compounds that bind with tannins, rendering the leaves indigestible. As soon as an acacia starts this chemical defence it warns other trees in the vicinity, forcing the giraffe to browse upwind in order to continue his love affair with these thorny trees.
