The buoyancy of ammonoids is one of the most controversial issues of ammonoid paleobiology. This chapter gives a short historical review about attempts made to clarify the potential function of the cephalopod chambered shell (phragmocone) and ammonoid life habits either as benthic crawler or as free swimmers in the water column.

Journal of Semantics, 2000
The chief characteristic of presuppositio ns is that they tend to take wide scope, yet most theories of presupposition, the author's not excepted, fail to provide an explanation of this fact. Recently, however, it has been suggested that a principled explanation can be given in terms of informativeness: the idea is that presuppositions simply prefer ...

There is a curious, intuitive fascination about buoyancy at great depths in the ocean. It was reported of ancient mariners that they feared burial at sea because they thought that the weighted body would only sink so far and no further. In some confused way, they thought the depths prevented the body sinking further, so it would drift with the currents.

The Physics Teacher, 2010
One of the most dramatic demonstrations of the Archimedes principle is the simple fact that battleships float. I estimate the depth of a battleship in seawater as an example in my physics classes. I use the battleship Arizona as an exemplar of a class of U.S. battleships used during World War II. The Arizona was 608 ft (185.3 m) long and 97 ft 1 in (29.

Buoyancy Regulation in Insects
PhysiologyMultiple insect lineages have successfully reinvaded the aquatic environment, evolving to complete either part or all of their life cycle submerged in water. Although these insects vary in their reliance on atmospheric oxygen, with many having the ability to extract dissolved oxygen directly from the water, all retain an internal air-filled ...

Since the pioneering efforts of Eric Denton and John Gilpin-Brown (1966), much has been learned about the buoyancy system of the chambered Nautilus. It seems timely, therefore, to evaluate critically what is known and not known about the buoyancy system of Nautilus, rather than merely to restate what has gone before. In particular, we will discuss what
