On the other hand, the land crabs are at an immense distance from these simple forms. The record of the Crustacean familytree is, in fact, a fairly complete E .Ps one - the lower primitive members s: of the group are still represented c' by living forms in great abundance.
The strange nobody-crabs or Pycnogonids occupy a place on the ascending half of the arc below the Eurypterines and Limulus.
When living near the coast foxes will, however, visit the shore at low water in search of crabs and whelks; and the old story of the fox and the grapes seems to be founded upon a partiality on the part of the creature for that fruit.
They include oysters, crabs of great size, and a small mussel, found in enormous numbers.
In consequence of the breaking away of the lower part of "Cleopatra's Needles" when removed to Alexandria and re-erected, the Roman engineers supported the angles on bronze crabs, one of which with three reproductions now supports the angles of the obelisk on the Thames Embankment.

Crabs are next in value and are caught chiefly along the East Shore and in Anne Arundel and Calvert counties on the West Shore.
The great catches are herring, cod and ling, but lobsters and crabs are also exported in large quantities.
The annual value of the shell-fish (lobsters, crabs, oysters, mussels, clams, periwinkles, cockles, shrimps) is about £73,000.
Next in importance were the catches of menhaden, shad, clams, squeteague and alewives; while minor catches were made of crabs, croaker, bluefish, butterfish, catfish, perch and spotted and striped bass.
The French authors argue that from the macruran lobsters (Nephropsidae) anciently diverged two lines: one leading through the Dromiidea to the genuine Brachyura; or crabs, the other independently to the Anomura proper, which may conveniently be named and classed as Macrura anomala.
- For the present, as of old, the true Brachyura are divided into four tribes: Cyclometopa, with arched front as in the common eatable crab; Catometopa, with front bent down as in the land-crabs and the little oyster-crab; Oxyrhyncha, with sharpened beak-like front as in the various spider-crabs; Oxystomata, including the Raninida, and named not from the character of the front but from that of the buccal frame which is usually narrowed forwards.
New light, however, has been thrown upon the "intellectual" capacity of Crustacea by the proof that the spider-crabs deliberately use changes of raiment to harmonize with their surroundings, donning and doffing various natural objects as we do our manufactured clothes.
A curious effect of parasitism, well illustrated in crabs, though not confined to them, has been expounded by Professor Giard, namely, that it tends to obliterate the secondary sexual characters.
The most abyssal of all crabs yet known is Ethusina abyssicola, Smith, or what is perhaps only a variety of it, E.
They agree with the true crabs in not having appendages (uropods) to the sixth segment of the pleon, the atrophy being complete in the Homolidae and Homolodromiidae, whereas in the Dromiidae and Dynomenidae a pair of small plates appear to be vestiges of these organs.
Bouvier (1896) has shown that Palaeinachus longipes, Woodward, from the Forest Marble of Wiltshire, is in close relationship, not to the oxyrhynch Inachidae, but to the genera Homolodromia and Dicranodromia of the Homolodromiidae, and that the Jurassic crabs in general, of the family Prosoponidae (Meyer), are Dromiidea.
- The Macrura anomala, or Anomura in restricted sense, are popularly known through the hermit-crabs alone.
They do not feed on fish, like true otters, but on clams, mussels, sea-urchins and crabs; and the female brings forth but a single young one at a time, apparently at any season of the year.
They include a jelly-fish, molluscs, prawns, crabs, &c., and were at first considered to form an isolated group found in no other of the African lakes; but this supposition has been proved to be erroneous.
The general practice for many years past among naturalists has been to restrict the terms "Insecta" and "insect" to the class of Arthropods with three pairs of legs in the adult condition: bees, flies, moths, bugs, grasshoppers, springtails are "insects," but not spiders, centipedes nor crabs, far less earthworms, and still less slugs, starfishes or coral polyps.

Shell-fish and crabs were taken, and seals knocked on the head with clubs, but neither fish-hook nor fishing-net was known, and indeed swimming fish were taboo as food.
Those frequenting the coast feed on dead fish, crabs and an occasional stranded whale, though they are also a danger to the sheep and cattle kraal.
Among shell-fish, crabs and oysters are taken principally off the east coast; the oyster beds in the shallow water off the north Kent and Essex coasts, as at Whitstable and Colchester, being famous.
CRUSTACEA, a very large division of the animal kingdom, comprising the familiar crabs, lobsters, crayfish, shrimps and prawns, the sandhoppers and woodlice, the strangely modified barnacles and the minute water-fleas.
A terrestrial habitat is less common, but the widely-distributed land Isopoda or woodlice and the land-crabs of tropical regions have solved the problem of adaptation to a subaerial life.
Lobsters and crabs are caught in Cardigan Bay, and oysters are found at various points of the Pembrokeshire coast.
