Same individual as seen on 4 July 2022, up in shallow water and moving across the reef. On image shows a very small part of its trail, which I followed for about 50m.

That's absolutely amazing!!! Your observations would be the world's first record of T. melanostoma egg. Thank you for sharing @susanprior (FYI- Glycymeris is my ex username).

Tagging other mollusc people as well:

Thanks @invertebratist . That explains why your other name wouldn't tag!
I had a feeling they might be. I searched high and low for something else but with no luck. I was so upset the morning I found them gone. When I mentioned to someone what had happened and what I'd been observing this person said 'never mind, there'll be more!'
Some people just don't get it! Hahahaha.

Wow! This is an awesome story @susanprior - I had never seen live T. malanostoma before - let aline the egg capsules. I have a feeling that these were able to make it into the ocean in due time ;)

I love the blog too btw.

@sultana Thanks for the nice comments. I'm hoping they made it too. The conditions were so bad in the last couple of days trying to photograph them (because I was only snorkelling) that I couldn't get a decent shot. But some of the capsules look to me like they may have emptied but maybe I am just being hopeful.
