And then the Lord withdrew His finger, and there were fibres and delicate root-like filaments adhering to the finger, and they were the nerve-threads of the filaments. And there was a gaping hole after the finger, which was God's finger, and a wound in my brain in the track of His finger.
That, however, detracts nothing from the marvel of their history and relationship. They send root-like organs deep into the mud, where they coil about some shell and there cling fast. Then the stem grows tall and slender, and upon the summit blooms or is developed the animal-flower.
Soon they block up the gland-tube, then begin to push out in the form of finger-or root-like columns of cells into the surrounding tissues. These columns appear to have the curious power of either turning their natural digestive ferments against the surrounding tissues, or secreting new ferments for the purpose, closely resembling pepsin, and thus literally eating their way into them.
Then it commences to undergo remarkable changes and finally becomes a mere sac-like organ with a number of long slender root-like processes penetrating and taking nourishment from the body of the unfortunate crab-host. The worms furnish many well-known examples of parasites, whole groups of them being especially adapted to parasitic life.
Rhizopoda means "root-footed," and the name is applied to these animals because most of them move about by means of root-like processes known as pseudopodia or "false feet." This is by far the largest class and contains thousands of forms, mostly living in salt water but there are many fresh-water species.
Clinging to the rough and root-like algae that fringed the ever-moist walls, John Rex crept round the projection of the gallery, and passed at once from dimness to daylight. There was a broad loop-hole in the side of the honey-combed and wave-perforated cliff.
"The rhizocephalous crustaceans do not feed like other animals by their mouths, for they are destitute of an alimentary canal, but they live by absorbing through root-like processes the juices of the animals on which they are parasitic."
Thomson as "elegant vases or cups, with branching root-like bases, or groups of regularly or irregularly spreading tubes delicately fretted on the surface with an impressed network like the finest lace"; and he adds, "When we compare such recent forms as Aphrocallistes, Iphiteon, Holtenia, and Askonema, with certain series of the chalk Ventriculites, there cannot be the slightest doubt that they belong to the same family in some cases to very nearly allied genera."
It penetrates into the crab in its larval stage, and passes entirely into the crab's body, where it develops a system of branching root-like processes. When mature the body of the Sacculina containing its generative organs forms a projection at the base of the abdomen of the crab on its ventral surface, and after this is formed the crab does not moult.
=Fibres of Clothing.= Microscopically, wool fibres are coarse, curly, and striated transversely; cotton fibres appear as flattened bands twisted into spirals; linen fibres are round, jointed at frequent intervals, with small root-like filaments; silk fibres are solid, continuous, and highly glistening. Signs and Symptoms. There are usually three stages: 1.
