Lobster claw leg.

Congenital split foot (lobster claw) and triphalangeal thumb.

Electromyographic analysis of goal-directed grasping behavior in the American lobster.

Animals spontaneously initiate goal-directed behavior including foraging action based on their appetitive motivation. The American lobster Homarus americanus exhibits grasping behavior with its crusher claw as feeding behavior that can be initiated after appropriate operant conditioning. In order to quantitatively characterize the goal-directed grasping behavior with a time resolution fine enou...

Spectrophotometric Studies of Penetration of Dyes

Spectrophotometric measurements show that the non-medullated nerve of a lobster claw is capable of absorbing methylene blue, azure B, or acid fuchsin dissolved in sea water but this does not necessarily imply that the dyes penetrate into the interior of the nerve.

Studies of Nerve Proteins. Isolation and Physicochemical Characterization of a Protein from Lobster Nerve

1. A procedure is described by which several protein constituents may be obtained from extracts of lobster claw nerves. One of these fractions, designated fraction A, representing 10 per cent of the total non-dialyzable material of the extracts, has been obtained in relatively (85 per cent) pure form. 2. This component has been characterized with respect to its physicochemical properties, parti...

Myofibrillar gene expression in differentiating lobster claw muscles.

Lobster claw muscles undergo a process of fiber switching during development, where isomorphic muscles containing a mixture of both fast and slow fibers, become specialized into predominantly fast, or exclusively slow, muscles. Although this process has been described using histochemical methods, we lack an understanding of the shifts in gene expression that take place. In this study, we used s...
