Cuttle fish come into torbay each year to breed and have had the pleasure of studying them in

shallow water.
A 2 hour dive in 5 to 10m (pending tides).... we took a deck chair each, set it up underwater, placed weights (rocks) on the legs and settled back for

some great observations.

1 from above, one cuttle (male) was communicating with a female alongside to its left. the whole left side of the male was a colour

show, but the right side was completly white and static.... apparently it is the males way of chatting up the fermale without letting others to the outward side know

what it is up to.

2 after several weeks of being in the same place, two cuttles were getting use to us and would come up and look into our face masks...... you

really have to experience it to know what words to use to describe it..... I wasnt sure who was studying who.

3 other patterns made, were when a large edible

crab disturbed one, whilst it was buried in the sand. It rose up, turned to face the crab and turned on a 'zebracrossing' pattern, which moved along the back to the

front and down their tenticles, giving the visual impression that they were 'flicking' something towards the crab.

got a lot to learn from the wet world.....

appreciated the experience............................. and we wern't charged for the deckchairs!

Great story. I would say they have an intelligence that is above most critters in the sea.

Especially when it comes to bouyancy! Many a badvis shore dive is due to who went in before (in our local club anyway Wink )

The sea is often called Inner-Space.... so these are the little aliens. Their inteligence seems very apparent.... but i

guess it is the shape and size of the eyes that make it look that way.
thanks for story, they are great, i could watch em for hours and come out a prune.. i wouldnt

mind Very Happy
