Yesterday, we found tens of small spherical jelly balls on a beach on the East coast of Norfolk. They were on the waters edge being washed in form the sea. Some were about the size of a traditional marble and some a little bigger, in addition to being spherical they were also grooved from top to bottom looking like giant beads. They were clear through but with thin strands of white inside. We wondered hat they might be, do you have any idea?

Tricky without seeing them. The high winds of the last few days may have generated waves strong enough to dislodge a colony of Clavelina lepadiformis AKA the lightbulb sea squirt. These guys are more elongate than spherical, but when washed up they may collapse in on themselves slightly (there's a photo here

Moon jellyfish may also fit the description, but these will be more or less flat when washed up - take a look here and to see if any of these jellyfish fit the bill.

These could also be eggs, although I'm afraid I don't know what they could be of without at least an image. The guys at might be able to help if they have had other reports.

A very useful website, with a lot of support, is run by the Marine Biological Association.
You can submit photos, which make identifying organisms much easier, to the site and your reports help with research as well.

As a general point, could people please try to send us photos of any organism they want us to try and identify and where in the world the saw/found it.
