In an attempt to remove all of the seaweed from the water because it was bothering Ruby (an attempt of the girls and a woman down the way, not Marla or I who understood the futility of the request), the girls discovered, in the holdfast of kelp, brittle stars. Brittle stars are in the same phylum of starfish (echinodermata) but have long flexible arms which help them move quickly. It was an exciting day at the beach. Brittle stars are incredible.
Over 70% of the earth's surface is covered with water, but only 5% has been explored. You can't help but wonder what is out there, but when surfing alone it is best not to wonder such things.
