Animal business

Description

'Give me this, I will give you that'. This universal definition of trade finds an equivalent in nature in a phenomenon call 'mutualism'. Shaped by evolution, it describes all long or short term exchanges and cooperation between animals to survive. It turns the traditional host-parasite relationship in a beneficial alliance for both partners. To describe mutualism this fascinating and well-documented episode travels from the cold ocean depths to the heat of summer corn fields where unexpected couples have formed: manta rays and remoras or osea cucumbers and shrimps for better or for worst.
