I found this on the beach at Nopolo last evening, along with another segment perhaps twelve long total. Appears to be a marine egg case of some kind?
The crescent shaped side was about 1.75” flattish individual segments were connected with a short segment of same membranous material. Kinda like
a spinal cord in total appearance.
Google has ruled out shark, ray, octopus, and I’ve tried to work through fishes, but that’s a big topic and it’s a big big thing for a fish.
Nope, not a jelly fish.
Anyone have an ID for me?

It's a Whelk egg sac, aka mermaid's necklace. DK had a resurrected post with a similar picture recently. David K - 7-25-2019 at 08:34 AM
