"HYAS AND STENORHYNCHA Marine Crustacea" "Four centimetres long... these spider crabs take their garb from their surroundings." "Each dresses to taste." "Seaweed on the tip of the nose is undoubtedly striking." "A ravishing ball gown..." "A simple sports outfit." "They are often difficult to distinguish from their environment." "The Stenorhynchus is graceful, with long legs and long claws." "A Stenorhynchus arrayed in seaweed." "The seaweed is attached to spines evenly distributed on the shell." "Here the Stenorhynchus melts into its natural surroundings." "Stenorhyncha arrayed in sponge." "Note the small mandibles." "The third pair of legs are for greeting." "The claws for confrontation..." "Enlarging the Stenorhynchus... conjures a near relation with legs two metres long and a habitat in far-off seas." "The Hyas is clumsy, with short legs and, usually, large claws." "Seen from below, the creature is identifiable." "Hyas covered in seaweed." "But from above, it looks simply like a clump of seaweed out walking." "This one is more quietly dressed." "Vertical seaweed stripes, the latest fashion." "Hyas covered in sponges." "Going to grotesque lengths..." "He is taken into custody." "The mandibles remain visible." "Praying Buddha." "An invitation to the waltz, behind which lurk dark designs." "Like all crustacea..." "They are arm-wrestling enthusiasts." "They're sometimes found in the vicinity of a worm the Spirograph, which inhabits a tube... and extrudes or retracts, spirally, its respiratory plume." "The worm is 15 centimetres long, its plume 4 centimetres in diameter." "In the centre of the plume is the mouth." "Here we can see the branchia of the plume increasingly enlarged." "An extreme enlargement shows the vibratile cilia... one thousandth of a millimetre long, covering the branchia." "They circulate the water, sending food particles to the worm's mouth." "The Japanese warrior." "Hyas and Stenorhyncha sometimes nibble the Spirograph's branchia." "A Stenorhynchus flees, rubbing its eye." "The caress of the Spirograph." "A Loie Fuller ballet." "Following a classical spiral retraction comes the firework display." "Subtitling TITRA FILM Paris"
