Few gelatinous animals can match the strangeness of this pelagic snail Sporting a muscular ventral fin it swims upside down in search of planktonic prey such as salps doliolids copepods euphausids and chaetognaths The conspicuous terminal mouth houses a radula used for feeding second photo With its developed eyes Carinaria actively swims while hunting gelatinous fare Escape or changes in direction are accomplished with rapid flexion of the body A thin laterally compressed conical remnant of the gastropod shell covers the visceral mass The body is mostly transparent with some red or bluish pigmentation along the fin margins Tubercles decorate the surface of the body in larger individuals which may reach astounding lengths approaching 50 cm although no more than about 13 cm is typical
