ABSTRACT Previous investigations with Ligia oceanica and prepupae of Drosophila melanogaster (Ellenby, 1951, 1953) have suggested that it may be possible to predict the level of oxygen consumption more precisely from a measurement of surface area (Drosophila) or body length (Ligia) than from body weight, in spite of the greater accuracy of the latter measurement. The point is now examined more closely ...

Descended from marine ancestors, Ligia oceanica , like other members of the sub-order (Oniscoidea or “slaters”) to which it belongs, has adopted a terrestrial mode of life. The other Oniscoidea have spread inland, invading regions far from the sea. Ligia, known as the sea-slater, is confined to the coastal fringe, and may possibly form a link between marine isopods and ...

1. Ligia is a nocturnal animal inhabiting crevices in rocks above high-tide level. It is omnivorous though Fucus spp. form the main article of diet. 2. Immersion experiments were carried out in which the animals were subjected to a gradual transition from salt to fresh water. None survived this treatment for more than one month. It was noticed that the reduction in salinity was accompanied by an increase in the rate of beat of the pleopods. 3. Animals were subjected to sudden and gradual changes ...
