Description

Barnacles and slow moving species, like this humpback whale have developed a symbiotic relationship, known as commensalism. In this case only the barnacles benefit from this relationship, without any biological cost to the whale. Attaching to the whale gives the barnacles a safe place stay, an endless supply of food and a free ride. Humpback whales migrate from cold Southern ocean waters to warmer waters along the South African coast line to calve and rest. They remain there until their calves are independent and strong enough to cope in colder waters. This image captures a playful, inquisitive young male, who decided to race our research vessel, putting up an impressive jumps and tail show.
