The proteolytic activity of the gastropod egg
Experimental Cell Research, 1957Abstract Two proteolytic enzymes, cathepsin III and leucine aminopeptidase, have been identified in the gastropod egg. The activity of cathepsin III was followed throughout the period of embryonic development.

Locomotion: The Cost of Gastropod Crawling
Science, 1980The power of locomotion of a terrestrial slug rises linearly with crawling speed. The metabolic cost of movement is 904 joules per kilogram per meter, considerably more than that reported for other forms of locomotion. This high cost is primarily attributable to the production of the pedal mucus by which the slug adheres to the substratum.

Microarchitecture and Deposition of Gastropod Nacre
Science, 1970The microarchitecture of gastropod nacre reveals deposition of aragonite in the form of crystal stacks and differs markedly from the characteristic microstructure of pelecypod nacre. The structure permits direct observation of both organic and mineral phases of deposition on a growth surface topography that is ideal for the study of processes of ...
