Nautilus pompilius Life History and Demographics at the Osprey Reef Seamount, Coral Sea, Australia
Nautiloids are the subject of speculation as to their threatened status arising from the impacts of targeted fishing for the ornamental shell market. Life history knowledge is essential to understand the susceptibility of this group to overfishing and to the instigation of management frameworks. This study provides a comprehensive insight into the life of Nautilus in the wild. At Osprey Reef fr...
متن کاملMemory of visual and topographical features suggests spatial learning in nautilus (Nautilus pompilius L.).
Previous studies demonstrate that soft-bodied (coleoid) cephalopods are adept at learning and remembering features of their environment, but little is known about their primitive relative, nautilus. Nautilus makes nightly migrations from deep to shallow water along coral reef slopes, covering large areas of varied substrate. Memory of its surroundings may be advantageous, but the nautilus brain...
متن کاملVentilation and Oxygen Uptake by Nautilus
The shell of Nautilus prevents the mantle from playing any part in creating the ventilatory stream. This is generated instead by movements of the collar and funnel folds which fuse to form flaps (the 'wings'), overlapping below and joined to the head above. The gills lie horizontally, dividing the space enclosed by the wings into three cavities, two lateral and prebranchial, on either side of t...
متن کاملNautilus - The Environment for Training and Testing
The paper describes an experimental web-based environment for teaching and testing. The application named Nautilus has been developed using Virtual Reality Modeling Language (VRML) and Java language with two special libraries: DILEWA and Vrmlworld. Although the resulting system is intended for low-level virtual reality systems without any specialized hardware support it is powerful enough to ac...
