We were lucky to find any starfish at all. The population up and down the Pacific coast came close to being wiped out in 2013. A rather nasty virus that melted these attractive creatures from the inside killed millions. Legs would fall off and go crawling away. It sounded like the plot to a Grade B horror flick. Fortunately, evolution came to the rescue. A small portion of the population seemed immune to the virus. Maybe some of the legs got lucky. They came back with a vengeance. We did find a few that were obviously dead. I touched one. It was mushy. Melting.
Here are some fun facts:
- These rather amazing five-legged creatures have seawater for blood. It serves the same purpose, delivering nutrients to cells.
- Starfish can regenerate an arm lost to a predator. But what if the arm loses its starfish? It can regenerate a new starfish, an exact replica. Pretty cool, huh.
- They have very small mouths but like large, tasty morsels, like mussels. Not a problem. They have big stomachs. They send them out through their mouths and wrap them around what they want to eat. They digest their dinner and then suck the nutrients back into their mouths, along with the wandering stomachs.
- They move around on tiny little feet that are found on their arms. They fill these little feet with water and mimic walking. They travel slowly, at least I have never seen one move quickly.
- The feet also serve another purpose; they work as suction cups. The starfish will wrap itself around a closed mussel, attach their little feet, and pull the shells apart. Not an easy task.
- One more thing about their arms, each one comes with eyes. Not eyes like you and I have but photo receptors that allow them to distinguish between light and dark and move around in search of food, or to avoid becoming food.

As you read this post, Peggy and I are on our way to Pt. Reyes National Seashore north of San Francisco. When she asked what I wanted to do for my birthday week, it popped up. The National Sea Shore is one of my all-time favorite places and I have been escaping there for 50 years. So, beyond responding to comments, I will be taking a break from blogging and reading blogs this coming week. Translate: Vacation! I’ll be back to work on March 8. See you then. –Curt
