Sorry, I didn't make myself

Sorry, I didn't make myself clear. I know what a notochord is, I was just using it for descriptive purposes hence the ref to a pikaia. This is the first time I've ever studied invertebrates. Just wanted to give as much detail as possible to help the identification.

Thanks
