19 A UST 1960 FLIGHT NATURAL SURVIVAL <EF»> S£/?/£S 77 BLOWS ITS OWN RUBBER DINGHY Generally sea-snails, being strictly non-swimmers,live on the shore or close-in on the bed of the sea, where life demands the minimum of effort, lanthinaJanthina, on the other hand, suffering the adversity of thin shell protection — and even that meagrecovering attractively coloured a deep violet-blue — seeks better odds for survival far out in sub-tropical seas. There it drifts safely attached to its own personal liferaft, nibbling occasionally at thepolyps of the Velella jellyfish, which is its staple diet, lanthina provides its own buoyancy chambers,blowing bubbles from a mucus not unlike rubber solution, which hardens on contact with the water. Thebubbles are tough and difficult to puncture and will remain intact long after the snail is dead. They arejoined to form a raft, which also serves as a floating pram, with eggs attached to the underside. The realisation that creatures other than we humans use inflatable liferafts may be somewhat surprising. What is not surprising, however, is the pre-eminence of R.F.D. as pioneers of inflatable safety equipment for air/sea survival. Today the development of better and better R.F.D. liferafts continually sets new standards of safety aboard the world's aircraft — both civil and military.
