This octopus was out in the open in shallow water when encountered:
No, the octopus was holding both my hands, it’s two front tentacles each side on my hands. When I pulled gently to release myself, it changed colour rapidly back to a darker colour and then jetted away. It was much smaller than me, but seemed very curious - tasting me to see if potential prey?amazing as usual @Tom Hlavac! What prompted the face-full of ink; was it a bit too much tugging?
