Whose ? egg case

This photo was taken last summer during our ongoing Posidonia research program in the Med, and I am still trying to find out what it is.

It was firmly attached to a Posidonia leaf and measured approx 1cm diameter by 1.5cm high. Looked like an egg case, but of what?

Any suggestions?

Looks like a very typical bobtail squid or cuttlefish egg, and judging by the fact it's on a seagrass blade it belongs to one of the smaller species.

Thanks Worm Girl.

I have seen many cuttlefish in the same area, but what does a bobtail squid look like? Do you happen to have a photo so that I can look out for them? Are they nocturnal?

Bobtails are adorable little squids with round bodies & stubby fins that tend to live buried in the sand during the day or among sheltering seagrass, corals, etc. They come out at night to feed & mate. I don't have a photo to post but a google image search produces about 200 photos of these charismatic cuties.
