Mystery eggcase
When I went diving earlier this year (beginning of May) me and my buddy found this egg case:
http://www.underwater.com.au/index.php/page/gallery/node_id/787.html
It was about 6 - 8 cm in diameter and looked sandy (we didn't touch it), but later when I found a similar thing on the beach it actually felt rubbery and was quite flexible and strong. Location: Julian Rocks, Byron Bay. Depth: 10 meters.
Who could tell me what creature constructed this (probably a mollusc of some kind)?
Thanks,
Wandy

- I see them all the time. All up and down the east coast.
I think it could be excrement out of the back end of a mollusc rather than an egg case.
Just a thought.
Some are quite small a few centimetres across and some up to say 10cms.

- Hmmm....it looks a bit too organised to be some excrement
Anyway, I have been in contact with someone from the Southern Cross Uni who confirmed it was an egg case, probably from some species of moon snail (Naticidae).
Thanks!

What is our Coral Sea?
- The Coral Sea is a tropical marine jewel, which lies east of the Great Barrier Reef Marine Park. It is one of the last places on Earth where large marine animals can still be found in great numbers.
