Next time you are kayaking in Elkhorn Slough take a look around the launch area. There is a vast diversity of life clinging to the docks and hiding in the mudflats. The bright orange species is a colonial tunicate. In their larval stage tunicates sport around with a primitive spinal cord which places them into phylum chordata, the same category that humans and all animals with backbones belong to. Our naturalist at www.bluewaterventures.org  love to share their knowledge of what lives above and below. Be sure to fire those questions our way on your next kayaking tour with us.
