Monday 29 May; Bank holiday Runswick bulletin.

Weather: misty, drizzly, slight breeze not a good beach day.

Tides: low water 1335 (0.8m), high water 19.42 (5.6m).

Natural history of Runswick Bay of the day:

This blobule is a ctenophore or comb jelly or sea gooseberry. While not clear on this pic, it has rows of hair like cells called cilia that run vertically along its body that beat the water to propel the creature along. They are washing up in large numbers on the beach night now and are harmless to handle but die and decompose very quickly if kept out of water for any length of time.
