We are grey hairs, living on a sail boat. Since being stuck in Bonaire, Dutch Caribbean, at the beginning of Covid, diving has become a big part of life, in a variety of places, often out of the way. Currently in Fiji.

I like taking photos of things I notice underwater and working out what they are. I've only recently discovered iNaturalist and am delighted to find such a range of people, amateurs and professionals, who share a passion for "groblets" as my other half calls them.

A special thanks to the identifiers who do such a great job, with such great patience!
