Recluzia shares 6 traits with epitoniids; Janthina has none. This details to Recluzia since the transitional form, which lends aid on the egg mass speculation. Using this approach, males would need to keep on with ladies to possess a raft. The evolution of autonomous float constructing by juvenile Janthina species removed the necessity of Conference a female in advance of metamorphosis.
The snail’s dependence with a raft of bubbles impacts its posture on the drinking water.
