Invertebrate day

Overnight rain finally cleared by mid morning, but it remained overcast for most of the day. A light NE breeze.

South shore
I had a walk from the saltmarsh to Red Nab before the rain had completely cleared (Malcolm). There wasn't much to see!

No sign of any Rock Pipits

Now four Wheatears along foreshore. 3 males and a female.

It's "green jelly blob" time of year again. The difference this year is that they are high definition jelly blobs. These blobs are typically 15mm diameter, and are the egg sacs of ragworms.
Unfortunately, high definition jelly, just looks like jelly.
Although if you look closely you can make out some black specks

In the next three shots, the jelly blobs are in shallow pools

The light offshore winds so far this spring has been good for the ragworms
that produce these egg sacs. Many of the sacs are still secured where the worm
left them. Most of the ones that break free end up in the strand line. Although,
presumably a few will drift to other suitable locations. 

This sac has ruptured, if you open this shot and zoom in you can see the tiny
eggs with dark embryos. They look like microscopic frog spawn. Presumably
the eggs will now be prone to predation, but surely some will mature.
