"Skeleton Shrimp and Spider Crabs" "Skeleton shrimp are classified among crustaceans." "They are thread-like, about one centimetre long." "This passing shrimp shows the size of a skeleton shrimp." "They are mostly found among algae." "With the hooks on their legs they can cling to anything." "Ship wreckers on a raft." "A tiny starfish is given a rough time by furious skeleton shrimp." "They are real acrobats among the algae." "The head with its appendages." "The head carries big and small antennae." "In front of the mouth, there are two legs for chewing." "The hook on the leg." "Two small breathing appendages are fixed on each side of the body." "Bending in three is a typical posture of the skeleton shrimp." "The first pair of legs, on the hind part of the body, carries venomous hooks." "These venomous legs are very big among males." "Circulation in the legs and the body." "Notice the one way arrival and departure of blood cells." "The heart stretches along the skeleton shrimp's back." "The intestine is agitated by the movement of the cardiac blood vessels." "They can swim by fits of the whole body... or by sliding on the sand." "We're going to follow a running skeleton shrimp." "Here is a skeleton shrimp cleaning one of its legs." "They never stop curtsying." "At a given moment, two lamellae appear under the female's abdomen." "The eggs go down through these lamellae and are stirred by the incessant movement of the lamellae." "She hasn't lost her agility." "This movement of the lamellae bathes the eggs in constantly renewed water." "The skeleton shrimp's soliloquy." "An egg, shortly before hatching." "We can see the baby's movement, rolled up in the egg." "The small skeleton shrimp come out by sliding between the lamellae." "The baby skeleton shrimp already has the adult shape." "The lamellae, after the children have left." "Sincerely yours." "Spider crabs are related to crustaceans." "(However they present certain characteristics proper to spiders.)" "Like the skeleton shrimp, they can be found among algae." "They have a tiny body which forks out in very long legs." "The body measures 5 millimetres and the legs 25 millimetres." "The head and its chelicerae" "(horns at the front of the head)." "We shall see certain organs pulsate." "Like all the organs, they fork out in the legs." "The body is in fact too small to contain the organs." "In a leg." "The legs have hooks;" "this enables the spider crab to live in the same habitat as the skeleton shrimp." "With this magnification, the hook seems to be quite far." "The spider crabs swim with all their legs and walk like spiders." "The underwater landing of a spider crab." "The eggs are shaped inside the female's legs." "The organs which shape the eggs, are ramified in the legs, like all the organs." "Once the eggs are laid, they gather around two hooks on the male's abdomen." "These make him look as if he were carrying two life buoys." "When ready, all the little spider crabs hatch at the same time." "The baby spider crab calls to mind a charming human parasite." "A farmer cultivating the land, seen from behind." "The baby spider crab is very different from the adult." "As it grows, the body remains small, the legs stretch out, and the organs are forced to ramify into the legs." "Once freed of the eggs, the carrier hooks are very visible." ""La Danse macabre""
