The low fishing pressure around Ereikoussa means grouper here are conspicuously larger and less wary than on mainland dive sites. Large males hold territories over the deeper reef sections below 15 metres, emerging to investigate divers with a boldness rarely seen in fished areas. Their territorial behaviour and tolerance of divers makes them the de facto ambassadors for the site's protected character.
