The comparative morphology of pit organs in elasmobranchs.
The pit organs of elasmobranchs (sharks, skates and rays) are free neuromasts of the mechanosensory lateral line system. Pit organs, however, appear to have some structural differences from the free neuromasts of bony fishes and amphibians. In this study, the morphology of pit organs was investigated by scanning electron microscopy in six shark and three ray species. In each species, pit organs...

متن کاملBacterial diversity of bacteriomes and organs of reproductive, digestive and excretory systems in two cicada species (Hemiptera: Cicadidae)
Cicadas form intimate symbioses with bacteria to obtain nutrients that are scarce in the xylem fluid they feed on. The obligate symbionts in cicadas are purportedly confined to specialized bacteriomes, but knowledge of bacterial communities associated with cicadas is limited. Bacterial communities in the bacteriomes and organs of reproductive, digestive and excretory systems of two cicada speci...
متن کاملMicropuncture studies of formed-body secretion by the excretory organs of the crayfish, frog and stick insect.
In the course of investigations of the formation of urine by the antennal gland of the crayfish it was discovered that this process involved the secretion of formed bodies. The appearance and partial chemical analyses of the formed bodies of the crayfish are reported on elsewhere (Riegel, 1966). In the present report the lipid character of the walls of the formed bodies will be established, as ...
