It was so hard to get a good look at them but some of the rock pools had some kind of shrimp in them. I could just barely make them out, and definitely couldn’t get any pictures. Love seeing invertebrates!

Wow, I didn't know that! I move a lot around my country for my work and I make it an habit to snap pictures and post any interesting flora and fauna to iNaturalist. Many times I even post pics of common weeds and I found out they have some cool names and properties! In fact I learned about a lot of new herbs which I thought were just weed. I love iNaturalist, learned a lot from the community. Everybody should give it a try. What's normal or common for you might be a new discovery for someone else.
