The secretion of chitinases in the digestive tract of most fish species indicate that fishes must play an important role in the recycling of chitin carbon and nitrogen. Some fish species are equipped with B-1,3 glucanases (or laminarinases) generally secreted by their own intestinal mucosa, and are thus able to take part in the biodegradation of B-1,3 glucans such as laminarin, leucosin, paramylon, etc. On the contrary, fishes seem to be entirely unable to digest cellulose and thus can hardly play any role in the biogeochemical cycling of this important organic compound.

The interest of the chemical composition of molluscan shells in phylogenetical considerations is illustrated by the case of Neopilina. Chemical analyses of organic matrix of the different shell layers of Neopilina galatheae rovealed the presence of chitin in nacrous and prism layers. Chitin is lacking in periostracum. The proportion of chitin is low (about 3.3 % of shell decalcified weight). Both microstructural and chemical caracteristics are in favor of a closest relationship of Monoplacophora with primitive Conchifera rather than with Amphineura. [less ▲]

Despite the appearances, the Thaliacean fauna of the Red Sea (as well as the fauna of the Persian Gulf) is of an indo-pacific origin. Only a few worldwide scattered species are common with the eastern Mediterranean. Owing to the severe environmental conditions (heat and mostly high salinity) and the presence of sills, the fauna of the Red Sea and especially those of the Gulf of Suez and of the Persian Gulf, are poorer than the fauna of the Indian Ocean proper and of the Gulf of Aden.

The structure and the composition of the cuticule of the Tardigrada Macrobiotus sp. and Milnesium tardigradum are studied. The cuticle is always made of two distinct layers extending to the stomodeum. By the two species, the cuticle contents, besides chitin, acid mucopolysaccharides and protids. These facts are arguments to bring nearer Tardigrades and Arthropods. [less ▲]

Whereas the jaws of the axial proboscis of Perinereis cultrifera and Sthenelaïs boa (Nereidae and Aphroditidae) are completely destroyed by hot alcali, the two-paired systems of maxillar pieces of certain species of Eunicidae are build up of proteins, mineral salts and chitin. The quantity of chitin is relatively low and amounts approximately 0,13 % of the total dry weight. [less ▲]

A method has been improved in order to estimate the flexiral rigidity and the Young's Modulus of the elytrae of 35 species of Coleoptera. The data of flexiral rigidity obtained in the case of genera belonging to the so called "Malacodermata" (in the meaning of Latreille) and of Pyrochroa are comprised between 20 and 200 mg.mm2, whereas those of other Coleoptera are considerably higher (between 1,700 and 357,000 mg.mm2). However, the values of the Young's Modulus are nearly always comprised between 500 and 1.300 kg/mm2. This observation confirms the opinion rigidity differences between "Malacodermata" (with soft integuments) and "hard" Coleoptera, only rely upon the relative thickness of the integument. Quite different is the case of Malachius bipustulatus, in which the very low Young's Modulus value indicate a peculiar constitution of the elytra. [less ▲]

1. The anatomical structure of the stomach in the didactyl sloth Choloepus hoffmanni Peters - Mammal of the sub-order of Xenarthra, family of Bradipodidae - conforms to the descripttion of that of Choloepus didactylus. 2. The histological features of the various paunches of the stomach in Choloepus hoffmanni are similar to those already described in Bradypus cuculliger, a tridactyl sloth. 3. The cardial paunches and the "fundus" of the stomach in the sloth are homologous to the rumen of Ruminants although the "fundus" secretes mucus. The glandular prepyloric paunch in the sloth is homologous to the abomasum. The reticulum has no anatomical counterpart in the sloth. The reabsorption of the water content of the stomach, which in Ruminants occurs mainly in the psalterium is performed by the prepyloric muscular paunch in the sloth. 4. Microscopical observations on stomach contents of the sloth showed the presence of a rich microbial population. No ciliates have been observed. 5. The bacteria hydrolyse cellulose into sugars. 6. Reducing sugars are in turn transformed into short chain volatile fatty acids, 370-950 uM/10 ml, an amount similar to that found in the rumen of the Sheep and Setonix brachyurus, a macropod Marsupial. 7. These fatty acids are reabsorbed by the gastric mucosa and transferred to the gastric venous blood as found in Ruminants and in a herbivorous macropod Setonix brachyurus. 8. The evolutionary convergence of this ruminant-like digestion is discussed. [less ▲]

The analysis of three samples of Graptolites extracted from calcareous stones from Silurian and Ordovician sediments shows the persistence of scleroproteins. The amino acids composition of these fossil proteins has been identified : the samples so far studied exhibited a very similar amino acid pattern. Other analyses indicate the absence of chitin in the samples studied. The chemical composition of Graptolite skeletal formations was compared with that of recent organisms and used as an argument in a discussion of the systematic affinities of Graptolites. [less ▲]
