Specifically it is a knobbed whelk. Channel whelk egg casing are smooth around the edges.
If you have a knife you can slice a segment, which will reveal tiny whelk no bigger than a pin head. If there is a tiny hole in the segment the whelk have already hatched out.
Typically these are found washed up on beaches, dried out and non viable.

From Wikipedia:
Reproduction[edit]
Whelk egg case
Mating and egg laying occur during the spring and fall migration. Internally fertilized eggs are surrounded by a transparent mass of albumen, a gel-like material, and are laid in protective flat, rounded egg capsules joined to form a paper-like chain of egg cases, commonly called a "Mermaid's Necklace". On average each capsule contains 0-99 eggs, with most strings having 40-160 capsules. After laying their egg cases, female knobbed whelk will bury one end of the egg case into the substrate, thus providing an anchor for the developing fertilized eggs and preventing the string of egg cases from washing ashore where it would dehydrate. Fertilized eggs develop in the capsules. Young emerge with a shell approximately 2–4 mm in length.
Young are preyed upon by crustaceans, horseshoe crabs, and fish, primarily drum species. Adult whelks are eaten by loggerhead sea turtles.

Whelk egg case probably from the Knobbed Whelk. WE have found them on the SW Florida beaches just about every time we have visited. Made for a great research project for the kids when we first started finding them. Hard to believe that a seashell starts from an egg case.

I have never seen a sea snake skeleton, but I have seen a whole “school” of sea snakes in the South China Sea, and we kept our distance - most are VERY poisonous.
