Monday’s Macro: Purple Sea Snail (Janthina prolongata)

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.
