Bubble snails

We’ve learned lots from the GoPro camera under the water with Nik and Marin in kayaks among the eel grass. We decided ( after google and my books) that the curly cue things are bubble snail egg cases ( up to 500 eggs each) but the snails lurk lower under water, the shells usually too small for the body. Google them if you are interested.
A good day for Oskar who got Zoey to help finish his shoes, made cookies and then a raft that floated.
