A Purple sea snail with egg capsules washed ashore after a sea storm. As a pelagic dwelling mollusc, it hangs upside down from a raft of mucous-coated bubbles. Preys on jelly fish, crustaceans and zooplankton. A single float can carry 250 to 400 egg capsules of varying ages. Each capsule can contain 75 to 7500 embryos per capsule. The young will be born as fully formed snails.
Nature on the Edge 
Incredible, Liz! I have never seen anything like it and wouldn’t have had a clue what was dangling from the snail had I seen it by myself.
Isn’t that ingenious, an incubation nursery suspended from a bubble raft? Nature has so many neat tricks up her sleeve.
This is very interesting.
Thanks for the comment Anne. Interestingly the same storm washed up blue bottles and velella, both prey items and free floating on the surface of the open ocean….
